Texto completoResumen
Istanbul is a megacity with a population of over 13 million. Due to experienced droughts and population growth in the city, interbasin water transfer from Melen Watershed was considered as the most feasible alternative to supply water that can compensate for water demand in the future. This decision changed the beneficial use of the Melen Watershed from irrigation water supply to drinking water supply and necessitated extensive pollution prevention measures to comply with the new water quality requirements. A Watershed Protection Action Plan was developed for the sustainable management of Melen Watershed. The action plan included measures concerning wastewater management, diffuse pollution management, solid waste management and water quality monitoring. In this paper, proposed protection actions in the plan are provided together with the activities realized so far. In addition, the changes made by the authorities during implementation of the plan are presented. The proposed Watershed Protection Action Plan as approved by the government is one of the first examples in Turkey, where watershed-based planning of water resources is implemented instead of administrative boundary-based management.

Abstract Listing of watershed management goals/targets is one of the integral parts of the management plan for a watershed. In this paper, we have listed 18 watershed management targets for which the Malaysian watersheds could possibly be managed in future. Based on the listed watershed management targets, the priority ranking of 18 targets is developed from the relative importance weights obtained from a survey conducted from 29 stakeholders. Three weighting methods (SWING, SMART, and SMARTER) were applied to elicit weights. We found that the SMART (Simple Multi-Attribute Rating Technique) weighting method was a favorable method for eliciting stable sets of weights for the watershed management targets. The SWING weighting method produces better weights than the SMARTER method. The listed watershed management targets will assist watershed managers and decision makers in decision making to use available resources (e.g. water quality, land-use, groundwater, and many other resources) in a more efficient and sustainable manner. The efficient utilization of all resources within a watershed will ultimately save watersheds (more specifically the urbanized watersheds) from further deterioration caused by unchecked infrastructure development activities

Texto completoResumen
The Town of Bluffton, South Carolina was a one square mile coastal village until it experienced exponential growth in the early 2000s, and today is approximately 54 square miles. Until this recent growth, few sources of possible impairments to water quality were recognized within the watershed, and even fewer within close proximity to the river itself. In 2007, the Town was told by the S.C. Department of Health and Environmental Control (SCDHEC) that fecal coliform levels in the May River headwaters were increasing and in 2009 the river received a shellfish harvesting classification down-grade. In response to this down-grade, the Town of Bluffton, with Beaufort County and stakeholders, committed to take action to restore shellfish harvesting in the river and to prevent further degradation to the river. Following the U.S. EPA (EPA) guidelines for developing watershed plans, Town staff worked for nearly a year with consultants, Beaufort County, topic experts and local residents to develop the May River Watershed Action Plan which was adopted by Town Council in November 2011.

Recent political envision has redesigned the administrative units of Nepal into federal states with the aim of decentralizing the power to ensure the process of rapid sustainable development. As a consequence, all the public service agencies need to restructure their delivery units for achieving goals targeted by the newly adopted administrative regime plan. With the aim of recommending the best watershed management models for this changing context, this paper aims to review existing watershed management models applied in different continents like European union, African union and the United States where they have already adopted this watershed management plans into their federal states or countries union successfully. Although they are geographically distinct and economically advanced, the major approach adopted is a river basin approach with the clear legislative framework. This approach is highly succeeded between interstate (or between member countries) because of political or interstate commitments for the common pool resource water. Clear policies and commitments between member countries or interstate greatly improved the function of this mechanism. With the light of those experiences in the field of watershed management plan adopted in federal or union countries, river based integrated management plan balancing efforts between interstates seems best models in the world, and is also proposed for the new federal republic of Nepal.

Texto completoResumen
Flood risk analysis is the instrument by which floodplain and stormwater utility managers create strategic adaptation plans to reduce the likelihood of flood damages in their communities, but there is a need to develop a screening tool to analyze watersheds and identify areas that should be targeted and prioritized for mitigation measures. The authors developed a screening tool that combines readily available data on topography, groundwater, surface water, tidal information for coastal communities, soils, land use, and precipitation data. Using the outputs of the screening tool for various design storms, a means to identify and prioritize improvements to be funded with scarce capital funds was developed, which combines the likelihood of flooding from the screening tool with a consequence of flooding assessment based on land use and parcel size. This framework appears to be viable across cities that may be inundated with water due to sea-level rise, rainfall, runoff upstream, and other natural events. The framework was applied to two communities using the 1-day 100-year storm event: one in southeast Broward County with an existing capital plan and one inland community with no capital plan.

A major research plan entitled “Integrated research on the ecohydrological process of the Heihe River Basin” was launched by the National Natural Science Foundation of China in 2010. One of the key aims of this research plan is to establish a research platform that integrates observation, data management, and model simulation to foster twenty-first-century watershed science in China. Based on the diverse needs of interdisciplinary studies within this research plan, a program called the Heihe Watershed Allied Telemetry Experimental Research (HiWATER) was implemented. The overall objective of HiWATER is to improve the observability of hydrological and ecological processes, to build a world-class watershed observing system, and to enhance the applicability of remote sensing in integrated ecohydrological studies and water resource management at the basin scale. This paper introduces the background, scientific objectives, and experimental design of HiWATER. The instrumental setting and airborne mission plans are also outlined. The highlights are the use of a flux observing matrix and an eco-hydrological wireless sensor network to capture multiscale heterogeneities and to address complex problems, such as heterogeneity, scaling, uncertainty, and closing water cycle at the watershed scale. HiWATER was formally initialized in May 2012 and will last four years until 2015. Data will be made available to the scientific community via the Environmental and Ecological Science Data Center for West China. International scientists are welcome to participate in the field campaign and use the data in their analyses.

Four indices which include surface runoff, soil erosion, agricultural nutrient loss, human and animal feces were selected and method to evaluate risk of non-point source pollution in watershed was constructed based on GIS. As a case, non-point source pollution in Dayanghe was evaluated. Results showed that very high risk area of non-point source pollution accounted for 3.41% area of the watershed, mainly located in farmland with steep slope along upper valley of the watershed. High risk area of non-point source pollution was located in farmland and human settlement placecs, accounted for 16.40% area of the watershed. Areas with low risk of non-point source pollution was riverbeds, shrub and grassland in eastern and western hilly with steep slope. Areas with lower risk of non-point source pollution located in middle of the watershed and accounted for 60.55% area. GIS-based risk evaluation system of non-point source pollution can reflect real map of pollution in the Dayanghe watershed and give implication for protection plan.

Abstract Sewage treatment studies at the watershed scale, compared to case-by-case community projects, ensures the most cost-efficient investment of funds commensurate with environmental requirements to sustain growth. A three-year environmental assessment study for the town of New Tecumseth, Ontario, examined all nutrient inputs to the Nottawasaga River watershed. Other challenging watershed constraints were investigated, such as stream and river flow takings for irrigation and sediment transport, prior to the selection of the master sewage treatment plan. The findings from the field research and computer modelling were used to (1) place a realistic perspective on nutrient impacts, present and future, attributable to treated sewage effluent; (2) design a master plan that could be used as an opportunity in terms of reusing the effluent locally for agricultural irrigation; (3) provide a real-time assurance of the plan’s performance/compliance, based on the actual carrying capacity of the aquatic ecosystem; (4) stage the construction of the plan in a cost-effective and environmentally sound manner; and (5) recommend a water resources management strategy to control other nutrient and sediment load sources within the watershed. The recommended master sewage treatment plan and water resources management strategy can restore the Ministry of Environment and Energy provincial water quality objective concentration for total phosphorus within the river during 7Q20 flow conditions.

Planning of conservation measures for watershed management and development is the method of preparing and implementing plans in different projects to maintain and raise watershed management functions which otherwise affect the plants, animal and human communities inside watershed boundary. The geospatial technologies like remote sensing and GIS, GPS are useful for fast and cost effective study of different applications with accuracy in planning. It also gives a good quality perspective for understanding the problems and therefore useful for planners for better result for sustainable water resource development and management. The main focus of the study is to develop the land and water resource development plan and environmental management for groundwater recharge development using Geospatial technology in Patur watershed which is situated in Akola district of Maharashtra. In this study various types of thematic maps have been generated from satellite images using remote sensing and GIS technology. These thematic maps were prepared from different types of data sets like IRS- LISS-III multispectral images, SRTM data with 30 m resolution and Survey of India Toposheet. The thematic maps for GIS analysis were created by image processing of the raw data using geospatial technology. A particular importance is laid on the planning of conservation measures for land and water resources management plan mainly based on the land use/ land cover, geology, geomorphology and slope of the Patur watershed area. The planning conservation activity should be important for ecological development and management at the forest area in the Patur watershed. From the final output of these study different conservation measures/structures like recharge wells, farm ponds, CNB, gully plug, CCT and other soil and water conservation structures have been suggested for groundwater recharge development, environmental management and to control soil erosion from the watershed area with reference to remote sensing and GIS data compared with ground truth.

The Forest Watershed and Riparian Disturbance (FORWARD) project input into the Millar Western Forest Products Ltd. Detailed Forest Management Plan consists of three main components: 1) watershed and stream layer maps and associated datasets; 2) soil and wetland layer maps and associated datasets; and 3) a lookup table that permits planners to determine runoff coefficients (the variable selected for hydrological modelling) for functional first order watersheds, based upon various site factors and time since disturbance. The watershed and stream layer component includes a hydrological network, a Digital Elevation Model, and Strahler classified streams and watersheds for functional first and third order watersheds in the entire Millar Western Forest Management Agreement area. Relatively coarse mineral soils (which drain quickly) and wetlands (which retain water) were the key features that needed to be identified for the FORWARD modelling effort; therefore, the soil and wetland layers represent a combined soil texture and wetland coverage. The runoff coefficient lookup table integrates predictions of hydrologic impacts of harvest into planning. Key words: forest management, watershed, hydrology, stream, soils, wetlands, modelling

The use and management of land resource which are unsuitable with its land capability will cause physical, chemical and biological-damage to the land and will disturb its hydro-orological function. The damage of land resources in a watershed needs improvement to increase its land quality. Optimal land use management planning based on its land suitability and hydrological aspects become important and need to be applied. The objectives of the study were: 1) To analyze land use change at Cijalupang Watershed, 2) To evaluate SWAT capability to predict impact of land use change on the hydrologic characteritics of the watershed, and 3) To provide land use plan based on land quality and hydrologic characteritics of the watershed. The result showed that optimizing land use management by integrating GIS and SWAT model at the Cijalupang Watershed was capable to increase land quality of the watershed. This was shown by the improvement of its land use capability to create better hydrological condition by decreasing run off 2.1 % and increasing base flow and lateral flow 0.4% and 0.4% respectively.

Each watershed has an overall hydrologic function to capture, store and safely release water. How well a watershed is able to perform this overall function is dependent upon how well each geomorphic component landform is functioning within the watershed. Each geomorphic component landform within a watershed has a specific hydrologic function and ecological potential. Component landforms that commonly occur in a watershed include stream channels, floodplains, stream terraces, alluvial valley bottoms, alluvial fans, mountain slopes, and ridge tops. When a component landform within a watershed becomes ecologically altered or degraded, its ability to perform its natural hydrologic and geomorphic functions becomes impaired and the watershed or ecosystem is unable to function properly. Component landforms within a watershed are interrelated. For example, the condition of a stream channel is closely related to the condition of its floodplain. Water from upland slopes is transported over and through alluvial fans and bottoms. Therefore, each component landform needs to be considered in the planning process and in setting watershed goals. This paper presents a simple field approach to inventory, evaluate and plan watershed restoration based on geomorphic, hydrologic and ecological principles. Examples of successful use of the approach on several watersheds in Utah, USA are given.

The Quebec Water Policy was launched in November 2002 in support of reform of the water governance. One of the government commitments is to gradually implement watershed-based management for 33 major watercourses located primarily in the St. Lawrence plain. At the local and regional levels, watershed organizations are responsible for implementing integrated management, from a sustainable-development perspective, by preparing a master plan for water (MPW), which will include watercourses, lakes, wetlands and aquifers. These watershed organizations rely on public consultation, as well as local and regional expertise, on the responsibilities for water of the municipalities and regional county municipalities of the territory, as well as those of the ministries and other government agencies. They are also required to observe national priorities regarding protection, restoration, and development of water resources and to comply with relevant guidelines, directives, standards, regulations, and legislation. The role of watershed organizations is to act as planning and consultation tables. Government representatives are present, on the initial process, as the facilitator and for scientific and technical support. They do not have, at this moment, any voting or decisional rights. After two years, integrated water management mobilized water stakeholders on watersheds and they are on their way to initiating their first MPW.

A watershed-based plan was recently developed for Murrells Inlet, a moderately tidal, euhaline estuary located on the northern coast of South Carolina. One of the goals of this planning effort was to collate and analyze existing data to refine assessments of the sources of fecal coliform detected by SC DHEC’s shellfish monitoring program. Coastal Carolina University’s Waccamaw Watershed Academy (WWA) was engaged to lead this data analysis effort. The most important sources identified were urbanized wildlife and canines. Results from the data analyses were used to prioritize subwatersheds for remediation. This has led to proposed strategies that focus on interception and treatment of stormwater runoff as well as volume reduction, dredging of tidal creek sediments, and outreach education for pet waste control.

A study was taken in a 1566 ha watershed situated in the Capivara River basin, municipality of Botucatu, São Paulo State, Brazil. This environment is fragile and can be subjected to different forms of negative impacts, among them soil erosion by water. The main objective of the research was to develop a methodology for the assessment of soil erosion fragility at the various different watershed positions, using the geographic information system ILWIS version 3.3 for Windows. An impact model was created to generate the soil's erosion fragility plan, based on four indicators of fragility to water erosion: land use and cover, slope, percentage of soil fine sand and accumulated water flow. Thematic plans were generated in a geographic information system (GIS) environment. First, all the variables, except land use and cover, were described by continuous numerical plans in a raster structure.The land use and cover plan was also represented by numerical values associated with the weights attributed to each class, starting from a pairwise comparison matrix and using the analytical hierarchy process. A final field check was done to record evidence of erosive processes in the areas indicated as presenting the highest levels of fragility, i.e., sites with steep slopes, high percentage of soil fine sand, tendency to accumulate surface water flow, and sites of pastureland. The methodology used in the environmental problems diagnosis of the study area can be employed at places with similar relief, soil and climatic conditions.

Cipunagara is the largest watershed in Subang Regency with River Cipunagara as the mainstream. Previous works showed increased activities around Cipunagara watershed, especially in segment 3, leading to a decline in the water quality. The importance of this river increases due to the development plan of Sadawarna and Cilame Reservoirs, which are used for irrigation and other activities. This study aims to identify pollution sources and to analyze the capacity of Cipunagara River in relation to potential pollution load from the watershed for the next 5 years. The study focuses on livestock, which is one of the main sectors contributing to pollution. The main steps include segment selection, calculation of existing pollutant load and prediction within the next 5 years from livestock waste. The segment selection was based on the number of activities from several sectors, the spatial plan of the region, as well as the quality and quantity Cipunagara River. The calculation of existing pollutant load was based on actual pollutant and flow of the river, while the prediction of pollutant load relied on emission factor of each pollutant parameter. The results showed that pollution index in Cipunagara River was severe. The existing and the projected potential pollutant loads in segment 3 include 1,668.76 kg/day and 2,081.25 kg/day for BOD; 4,053.74 kg/day and 5,063.29 kg/day for COD; 8.72 kg/day and 13.34 kg/day for N-Total; and 1.75 kg/day and 2.16 kg/day for P-Total, respectively. These results can be used by the local governments to manage water quality of the river.

Kritisnya DAS Binanga Lumbua berkontribusi pada penurunan pendapatan perkapita Kabupaten Jeneponto. Ini juga menjadi salah satu alasan mengapa Kabupaten Jeneponto menjadi satu-satunya wilayah di Provinsi Sulawesi Selatan yang termasuk dalam kategori daerah tertinggal.Jika melihat kondisi fisik wilayah ini yang mempunyai topografi variatif dan tanah yang subur,semestinya wilayah ini memiliki nilai ekonomi yang potensial untuk pengembanganhutan,tanaman perkebunan,maupun pertanian tanaman pangan. Hasil penelitian sebelumnya adalah identifikasi kekeringan dengan menggunakan pendekatan hidrologis secara kualitatif dan kuantitatif.Kemudian, memberikan arahan pemanfaatan ruang yang berbasis pada upaya pencegahan bencana kekeringan. Sehingga dalam penelitian lanjutan ini, tujuan yang akan dicapai adalah merancang konsep one river one plan dalam penataan DAS Binanga Lumbua secara komperehensif untuk mewujudkan pembangunan yang berkelanjutan. Analisis yang digunakan adalah berupa analisis spasial dan deskriptif kualitatif.Hasil penelitian ini berupa pemetaan konsep penataan DAS yang berbentuk site plan. The criticality of the Binanga Lumbua watershed is that it contributes to the decline in the income per capita of Jeneponto Regency. This is also one of the reasons why Jeneponto Regency is the only area in South Sulawesi Province that is included in the category of underdeveloped areas. Looking at the physical condition of this area which has a varied topography and fertile soil, this area should have potential economic value for the development of forestry, plantation crops, and food crop agriculture. The results of previous research were the identification of drought using a hydrological approach both qualitatively and quantitatively. Then, provide directions for spatial use based on drought prevention efforts. So that in this follow-up research, the goal to be achieved is to design a 'one river one plan concept' in the comprehensive arrangement of the Binanga Lumbua watershed to realize sustainable development. The analysis used is in the form of qualitative descriptive and spatial analysis. The result of this research is a mapping of the watershed planning concept in the form of a site plan

Nowadays, electricity is a basic human need that must be available. Therefore, efforts to obtain electrical energy from renewable natural resources continue to be explored, especially water energy from watersheds and sub-watersheds. Aceh Province is a relatively widely available area of watersheds and sub-watersheds. This study aims to analyze and categorize the potential of electric power generated by the Lawe Sempali sub-watershed, Aceh province, as a source of hydroelectric power. The method used in this research is the study of literature and field studies. The rainfall analysis of the ten year return period plan was carried out with four approaches, namely (i) normal distribution method (ii) normal log distribution method, (iii) Gumbel distribution method, and (iv) Pearson III log distribution method. Discharge plans that occur are analyzed using the rational method. The categorization of the power capacity of hydroelectric power plants is based on the capacity that can be produced by the sub-watershed. The results of this study were to report that the Lawe Sempali Sub-watershed has the potential to be a source of hydroelectric power generation in the category of micro-hydro and or small-hydro power plants. The capacity of electric power generated with planned discharge in the shortest return period (2 years) is a minimum of 68.21 KW (head 2 m) and a maximum of 3.41 MW (head 100 m).

Abstract. The watershed based integrated approach is considered as a more efficient and appropriate approach for resource appraisal and implementation of various sustainable development measures. The present study intends to demonstrate the application of geospatial technologies in preparation of comprehensive as well as an operational framework under Indian conditions to evaluate land and water resources patterns through a case study of Andipatti watershed, located in Theni district in the State of Tamil Nadu (India). The study used widely acclaimed various empirical and quantitative models to characterise the watershed and to understand the spatial pattern of potential-utilisation levels of the watershed resources. The study used mostly remotely sensed data for understanding surface characteristics and location enabled in-situ data such as soil, rainfall and groundwater data for understanding the sub-surface characteristics of the study area. All these datasets were integrated in a GIS environment to asses soil productivity, soil erosion, surface runoff, groundwater potential, groundwater quality, crop-land suitability, groundwater suitability for agriculture, determination of potential-utilisation index and to draw land use planning strategies. Since the methodology developed in the study is mostly depends on remotely sensed data, only minimal efforts are required for any agencies to prepare a similar systematic sustainable agricultural development plan.

Batang Air Dingin Watershed is one of the watersheds in Padang City which is located at 00050’12,5” to 00050’22,5” South Latitude and 100023’35,85” to 100022’42,84” East Longitude has changed its function. Land in the area around the river flow results in greater surface runoff, which has the potential to cause erosion. Runoff that occurs in Batang Air Dingin Watershed area causes the river to shrink during the dry season causing the local residents’ wells to be drought, while in the rainy season the river discharge value used is obtained. Through the calculation of the hydrograps discharge using the HSS Nakayasu and HEC-HMS methods whose values are validated by the field flood discharge. Hydraulic modelling using HEC-RAS software with discharge from HSS Nakayasu method. The retention pond plan is based on the amount of runoff that cannot be accommodated by the original storage capacity of Batang Air Dingin Watershed during 100 year return period was 1212, 94 m3/second with large river storage capacity is 1205,317 m3/second. The debit that can be deducted by making a retention pond is 30,5%.

Gandaki province has the good potentiality of hydro-electricity generation with existing twenty-nine hydro-electricity projects. Since the Province is rich in water resources, analysis of watersheds needs to be done for management, planning and identification of water as well as natural resources. GIS offers integration of spatial and no spatial data to understand and analyze the watershed processes and helps in drawing a plan for integrated watershed development and management. The Digital Elevation Model (DEM) available on the NASA-Earth data has been taken as a primary data for morphometric analysis of watershed in Gandaki Province using QGIS. Delineation of watershed was conducted from a DEM by computing the flow direction and using it in the Watershed tool. Necessary fill sink correction was made before proceeding to delineation. A raster representing the direction of flow was created using Flow Direction tool to determine contributing area. Flow accumulation raster was created from flow direction raster using Flow Accumulation Tool. A point-based method has been used to delineate watershed for each selected point. The selected point may be an outlet, a gauge station or a dam. The annual rainfall data from ground meteorological stations has been used in QGIS to generate rainfall map for the study of rainfall pattern in the province and watersheds using IDW Interpolation method. The present research work provides some major morphometric watershed parameters like drainage area, flow length, slope, drainage density and rainfall patterns for watersheds in Gandaki Province. Furthermore, the parameters were compared among the watersheds in Kaski. The results of this study can be used as a reference for proposing infrastructures in those watersheds and it can also be used for making policy by local government authorities related to Energy, Water Resources, Irrigation, and Infrastructures.

Abstract The City of Toronto has development a Wet Weather Flow Management Master Plan incorporating a new philosophy in wet weather flow management where rainwater is recognized as a resource. Wet weather flows are to be managed on a watershed basis, and a hierarchical approach to wet weather flow management is to be used, starting with at source, followed by conveyance and finally end-of-pipe control measures. The study area extended across the City of Toronto, encompassing six major watersheds and the waterfront. The Plan development followed the planning principles of Ontario's Environmental Assessment Act and incorporated broad public and agency consultation. A series of 13 objectives was identified and grouped into four major categories: water quality, water quantity, natural areas and wildlife, and sewer system. An innovative approach was used which integrated hydrologic, hydraulic and water quality predictions from land-based, watershed and lake models, respectively, to assess the effectiveness of various strategies. The receiving water response indicated that source controls and conveyance controls were insufficient to achieve the receiving water objectives of the Plan. This was only possible through the implementation of a comprehensive set of measures consisting of: source controls, conveyance controls, end-of-pipe controls, basement flooding protection works, stream restoration works, shoreline management, enhanced municipal operations and an enhanced public education and community outreach program. Overall benefits expected through the Plan include: swimmable waterfront beaches, control of combined sewer overflows in compliance with legislative requirements, basement flooding protection, protection of the City's infrastructure from stream erosion, restoration of degraded local streams and aquatic habitat and the reduction of algal growth along the waterfront, and improved stream water quality in area watercourses. The cost of the Plan over the 25 years is estimated to be $1.047 billion with an additional $233 million in operational and maintenance costs.

Lake ecosystem balance is influenced by the interaction and interrelation of upstream and downstream processes of catchment. Environmental degradation upstream affects the trophic status of the lake, triggering the risk of environmental disasters. Integrated lake management is a form of governance to achieve sustainable development goals. This study aims to analyze the implementation of the Rawapening Lake management program plan spatially by considering the environmental risk conditions of the Rawapening catchment area. Semi-quantitative analysis is used to assess the level of disaster risk in Rawapening catchment area. The zoning results of environmental disaster risk areas are used as the basis for the implementation of the 2019 Rawapening lake management plan descriptively. The results showed that Rawapening catchment area has a very low, low, medium, high, and very high risk levels. Panjang Sub Watersheds, Galeh Sub Watersheds, Parat Sub Watersheds, Sraten Sub Watersheds have a high to very high risk level. The Rengas Sub Watershed, Torong Sub Watershed falls into the medium risk category. Low to very low risk levels are scattered in the Legi Sub Watershed, the Kedung Ringis Sub Watershed, and the Ringis Sub Watershed. The complexity of the problems in the agricultural, livestock, residential and industrial sectors is the main contributor to sediment and pollutants in the lake system. The integration of upstream and downstream processes is used as a consideration in conducting spatial planning for Rawapening Lake management to achieve management objectives

Transboundary water pollution is a long-standing problem in China, although the Chinese government has been committed to the protection of water resources. Due to the different interests of multilevel governments and the regionalization of management, there is still no unified plan to solve the transboundary water pollution in China. Watershed ecological compensation as a holistic plan to deal with transboundary water pollution is being promoted currently. Taking the South-to-North Water Transfer Project’ eastern route as an example, this paper firstly analyses stakeholders’ strategies and establishes a tripartite game model based on evolutionary game theory. Secondly, by introducing Cobb Douglas production function creatively, the supervision level of the central government is refined into supervisory attitude and supervisory skills. Thirdly, the numerical simulation is used to analyze the sensitivity of influencing factors. The results show that: (1) whether the central government supervises the local governments mainly depends on the benefits of water environment improvement and supervision costs; (2) the initial negotiation plan of the stakeholders has a significant impact on their optimum strategies; (3) the fines imposed by the central government on the local governments have a small impact on the stable state of the system; (4) the higher the eco-compensation fee, the lower their likelihood of cooperation; (5) the central government’s supervisory attitude and supervisory skills have significant effect on the sustainability of the optimum arrangement, even when willingness of upstream and downstream governments to cooperate is low; (6) the initial ecological benefits of downstream governments have no effect on the optimum strategy. Therefore, considering these insights is helpful to improve the watershed ecological compensation mechanism in order to solve transboundary water pollution and achieve the sustainability of water resources.

In this study soil hydro-physical properties such as soil texture, available water capacity, and organic carbon, along with existing land use and topography of a representative watershed of eastern India (Kadalipal watershed, 20.80–20.86°N and 85.54–86.50°E, Dhenkanal district, Orissa), were spatially mapped after collecting data from different sources (ground-truthing, profile survey, remote sensing satellite imagery). Since availability of water is confined to the south-west monsoon period (rainy season, June–September), eastern India is mainly mono-cropped, dominated by rice but second crops can be planned based on the soil hydro-physical properties, mainly water retention and available water of the soil profile utilising residual soil moisture. Keeping the existing land use as a base and considering the potential and prospects of soil hydro-physical properties in different topographies, in this investigation, an alternative land-use plan was developed in different parts of the watershed and tested in its rainfed rice area. Since direct measurement of available water capacity or soil water constants over a large area is time-consuming, pedo-transfer functions were also developed to predict soil water constants using easily measured parameters (e.g. cation exchange capacity, organic carbon, oven-dry bulk density, soil texture, calcium carbonate, etc.) of arable land of the watershed. Results of implementation revealed that the new cropping system was practical for increasing production, productivity, profitability, and sustainability of the rainfed rice area of the eastern India.

Crop yield depends on multiple factors, including climate conditions, soil characteristics, and available water. The objective of this study was to evaluate the impact of projected temperature and precipitation changes on crop yields in the Monocacy River Watershed in the Mid-Atlantic United States based on climate change scenarios. The Soil and Water Assessment Tool (SWAT) was applied to simulate watershed hydrology and crop yield. To evaluate the effect of future climate projections, four global climate models (GCMs) and three representative concentration pathways (RCP 4.5, 6, and 8.5) were used in the SWAT model. According to all GCMs and RCPs, a warmer climate with a wetter Autumn and Spring and a drier late Summer season is anticipated by mid and late century in this region. To evaluate future management strategies, water budget and crop yields were assessed for two scenarios: current rainfed and adaptive irrigated conditions. Irrigation would improve corn yields during mid-century across all scenarios. However, prolonged irrigation would have a negative impact due to nutrients runoff on both corn and soybean yields compared to rainfed condition. Decision tree analysis indicated that corn and soybean yields are most influenced by soil moisture, temperature, and precipitation as well as the water management practice used (i.e., rainfed or irrigated). The computed values from the SWAT modeling can be used as guidelines for water resource managers in this watershed to plan for projected water shortages and manage crop yields based on projected climate change conditions.

Purpose This paper aims to find the pattern of interaction of political actors in situations of tenurial conflict in the watershed through a review of cases of social conflicts of plantation villages around Siak watershed 2009-2014. Design/methodology/approach In harmony with the Research Master Plan (RIP) of Riau University, the socio-political of Riau Malay society and the fundamental scientific pattern of Riau university, the development of the resources of area and waters and Malay culture, since 2001, the writer has conducted a study related to the issues of natural resources policy, especially oil palm in the era of regional autonomy and decentralization. This is in line with the umbrella of research developed by the University of Riau namely studying various aspects of natural resources (especially oil palm) and human resources of Watershed (DAS). The writer's review is; first, the dynamics of politics in relation to the issue of oil palm plantation policy in Riau. This study shows that there are many central policies when implemented at the local level including watersheds clashing with local interests such as forests and land ownership. Second, the writer has also reviewed the policy issues and problems of oil palm plantations in Riau watershed in 2000. This study shows there are many issues and problems formulated differently by different people. Findings Mapping and strategy are examined through the study of political strategies on oil palm plantations and use them to answer the following two questions: what kind of political model which can be used to manage the watershed conflict since regional autonomy is implemented. Economic factors are influential in mapping and management strategies for the emergence of tenurial conflicts in the Siak River Rivershed 2009-2014. The tenurial conflict management model of Siak rivershed, which is considered relevant, is a conflict-based model of cooperation with a partnership pattern between local government, watershed civil society and plantation business actors. The change of agrarian structure is directed to the effort to open the space for the accesibility of society in decision-making. Originality/value Some of these studies have not reached the tenurial conflicts in the watershed areas, especially Siak watershed. In fact, about 80 per cent of Riau province region consists of watershed. This becomes the originality and gap of this study with previous studies. This research was conducted further as an effort to synergize Riau's development policy with Riau University's research in harmony with RIP that was created and aimed to find the pattern of interaction of political actors in situations of tenurial conflict in Watershed through a review of cases of social conflicts of plantation around Siak watershed in 2009-2014.

AbstractModels have been developed to simulate the long-term effects of weed treatments across a landscape to determine effective management strategies, but those models might not be suitable for evaluating short-term action plans of weed treatments that are specific in time and place. In this study, we developed a simulation model to build and evaluate 5-yr weed treatment plan options in terms of their cost and effectiveness in minimizing total infestation areas over the short-term planning horizon. In an iterative, interactive process, 5-yr treatment plan options are developed based on user-defined weed treatment preferences, and evaluated in terms of total projected infestation areas at the end of the planning horizon. The simulation model was applied to a study area of 24,867 ha (61,447 ac) located in the Salmon River watershed in Idaho. Eight treatment plan options were developed using two treatment priority strategies and four increasing budget levels, and compared for their effectiveness. The application results showed that regardless of budget levels, site priority strategies were more cost-effective than the species priority strategies in reducing total infestation areas over time. This simulation model can provide weed managers with a useful tool to evaluate short-term treatment options, and thus support informed decision-making for effective weed management. Although the availability and quality of input data may be a practical limitation of using the simulation model, more data would become available and improved as more invasive species monitoring programs are implemented.

Simulation of soil erosion is an important phenomenon in watershed management studies because of the dynamic nature of soil. The present study demonstrates the capabilities of remote sensing coupled with GIS to extract soil erosion vulnerabilities using RUSLE model. Therefore this study understands spatial distribution of soil erosion at a macro-watershed scale. The input parameters for RUSLE model include the rainfall and erosivity (R) derived using the TRMM satellite precipitation product for a long term implementing regression model. The soil erodibility (K) factor is estimated using available soil map, and the topographic factor (LS) from 12m ALOS PALSAR DEM. The management practice information was extracted from the land use / cover map based on 30m multi spectral LANDSAT-8 of three season datasets. The RUSLE model predicted very low, low, moderate, high and very high erosion in 84.8%, 7.9%, 4.4%, 2.3% and 0.7% of reviewed area, respectively. The results were validated with ground infromation and NDVI, being the main identifiers of soil erosion. As presence of high vegetation indicates higher strength to hold the soil particles together and prevent soil erosion, correlation coefficient was generated to find accuracy of the results with NDVI of the area. The strong positive correlation (0.5) provided scientific support that prediction of soil erosion by RUSLE can be effectively used for watershed management and combating action plan for soil erosion.

River basin planning in Bolivia is a relatively new endeavor that is primed for innovation and learning. One important learning opportunity relates to connecting watershed planning to processes within other planning units (e.g., municipalities) that have water management implications. A second opportunity relates to integrating watershed management, with a focus on land-based interventions, and water resources management, with a focus on the use and control of surface and groundwater resources. Bolivia’s River Basin Policy and its primary planning instrument, the River Basin Master Plan (PDC in Spanish), provide the relevant innovation and learning context. Official guidance related to PDC development lacks explicit instructions related to the use of analytical tools, the definition of spatially and temporally dis-aggregated indicators to evaluate specific watershed and water management interventions, and a description of the exact way stakeholders engage in the evaluation process. This paper describes an effort to adapt the tenets of a novel planning support practice, Robust Decision Support (RDS), to the official guidelines of PDC development. The work enabled stakeholders to discern positive and negative interactions among water management interventions related to overall system performance, hydrologic risk management, and ecosystem functions; use indicators across varying spatial and temporal reference frames; and identify management strategies to improve outcomes and mitigate cross-regional or inter-sectorial conflicts.

This study mapped the land use and land cover of the catchment area of the Peixe-Boi River watershed, in northeast Pará, in order to identify conflicts of land use in the permanent preservation areas, and to relate them to water quality. We used LISS-3 sensor imagery from the Resourcesat satellite with a spatial resolution of 23.5 m for supervised classification of land use and land cover based on 22 training samples. Water quality was determined based on 28 sampling points in drainage network. The relationship between human disturbance and water quality was analyzed based on observations of land use changes using satellite imagery and in situ collection of water samples. The results show that 46% of the permanent preservation areas have conflicted uses, especially with respect to urban squatters, exposed soil and, most notably, pasture, with over 84 % of the area in conflict. Critical levels of dissolved oxygen reaching 2.14 mg L-1 and pH of 5.12 were observed in some sampling points. These values are below the fresh water standards set by Resolution 357/05 of CONAMA. The poorest water quality may be related to irregular use and occupation of areas within the permanent preservation areas. There is therefore an urgent need to develop a plan for the sustainable use and occupation of catchment area land in the Peixe-Boi River watershed in order to restore the environment and improve water quality.

To enable conservation of degraded land requires Map of Conservation Activity Plan (CAP). The map is established based on a model developed by the then Ministry of Environment and Forestry. One step to analyze the CAP is land unit elimination (LUE) having area of < 1 cm2. This study aimed to determine the effect of LUE on the CAP at Air Bengkulu Watershed. Maps used for input to CAP are EHL (Erosion Hazard Level), Soil Depth, Slope, Population Pressure, and the Recommended Landuse, whereas to calculate EHL requires R, K, LS, C, and P Factors. CAP Map as a result without involving LUE is compared to the CAP Map with involving LUE. The research result showed that the LUE influences on the change of the recommended of the CAP up to 77.6% of the total area of the study, either in engineering recommended or in vegetatively recommended conservation, while the rest (22.4%) were unchanged.

Batu Hijau mine pit is known as one of the largest copper pit mine in Nusa Tenggara Barat, Indonesia. Similiar as other copper mine pits in Indonesia, This site also faces acid mine water (AMD) problem. Based on the mine management plan, the AMD generated from this pit is being collected into Santong ponds in the southwest of the pit located in the upstrean area if Sejorong watershed. By the next decade, Batu Hijau mine will be in the closure mine period and it is important to understand the probable movement of AMD under the Santong ponds whether the AMD leaked to groundwater or not. This research aims to develop a numerical model of groundwater flow and predict the movement of AMD by applying particle tracking method. Secondary and primary data of geology, hydrology, and hydrogeology. Also, groundwater pumpage discharge information was collected and analysed to develop hydrogeological conceptual model and the numerical model. The conceptual model of hydrogeological system in the research area is known to be built on unconfined aquifer system from a combination of weathered and fractured volcanic rocks in the upstream to middle part of watershed and majorly by alluvial and coastal deposits in the downstream area. The thickness of aquifer is vary between 20 to about 300 m and divide into 5 layers in the numerical model, with hydraulic conductivity ranges between 5 to 100 m/day and groundwater recharge is vary between 180 to 700 mm/year from downstream to upstream of watershed. Groundwater flow boundaries in the Sejorong watershed are mainly controlled by topographical feature as water divide boundaries and the existing of Sejorong parennial rivers in the middle of this watershed. Steady state particle tracking results from the numerical groundwater flow model show AMD from Santong ponds may migrate in groundwater only to a distance of about 500 m to the downstream and therefore it is unlikely that AMD seepages from Santong pond may contaminate water in the production wells

Rainfall analysis and slope, soil type and land use analysis are needed to determine the amount of discharge plan using the Rational Method that can influence the magnitude of power potential in each sub-section of the upstream part of the Krueng Aceh watershed. Rainfall needs to be calculated with statistical parameters to determine the distribution that can be used so that a rainfall plan can be obtained. Slope map overlay, soil type, and land use to obtain runoff coefficient (C). This study uses 10 years of rainfall data for the 2009-2018 period, as well as 2016 spatial data. The amount of the rainfall plan is obtained from the calculation of the distribution that meets the requirements in the study area, namely the Log Pearson III Distribution in a certain return period, the rainfall plan is obtained, the greater the value along with the increasing return period. The plan debit obtained from the calculation results using the Rational Method in a given return period varies the value of the discharge, the longer the return period used, the greater the maximum debit obtained. Potential Power generated from the theoretical calculation results in a certain return period is obtained the value of the power that is included in the classification of power plants that range from 5 kW-100 kW. The results based on the Likert Method show that the website containing the power potential of PLTMH in the upstream part of the Krueng Aceh watershed has been good and successful.

Erosion is a form of land degradation is very serious in Koloh Pasiran watershed. This condition perceived more severe by the fact that the understanding of the process of saving the natural resources of forest, soil and water have not received maximum attention. This is evidenced by the presence of illegal logging, forest fires around the area of the watershed during the dry season and flooding during every rainy season. Therefore, the research conducted with the aim to: 1) determine the level of erosion and soil and water conservation planning in the Koloh Pasiran watershed, 2) determine the land capability class in Koloh Pasiran watershed and 3) to plan land use capability classes based on erosion rate. Observations and sampling of soil samples for prediction of erosion, soil conservation and classification approach according, planning based on common land unit. This land unit maps obtained from the land use maps overlay by slope, soil and land use maps done by estimating the magnitude of the erosion equation USLE (Universal Soil Loss Equation) of Wischmeier and Smit (1978). Determine land capability class with land capability classification approach according Arsyad (1989). Land use planning and soil and water conservation in addition to using USLE equation also uses land capability classification according Arsyad (1989). The results show the level of erosion prediction calculation slight to very severe erosion. Mixture of garden soil with a 2% slope erosion rates relatively slight. Dry land with a slope of 2% classified as severe erosion and the shrub land with a slope of 2-3% erosion classified as severe to very severe. While in secondary forest land and primary forests with a slope of 2-25% relatively slight erosion. Land capability class in Koloh Pasiran watershed can be classified into class IV (3 units of land), class V (5 units of land), class VI (1 unit of land) and VIII (2 units of land). The limiting factors are: (e) the slopes are steep and severe erosion rate and (s) low water holding capacity. Direction of land use for high density mixed garden with bench terrace with good construction, dry with good bench terrace construction and given a booster plants around the lip of land, shrub land used for community forestry, agroporestry and natural forests, while for secondary forests and forest maintained primary sustainability

The goal of this research is identifying major sources of uncertainty of an environmentally-sustainable urban drainage infrastructure design, based on hydrologic analysis and life cycle assessment (LCA). The uncertainty analysis intends to characterize and compare relative roles of unreliability, incompleteness, technological difference, and spatial and temporal variation in life cycle impact assessment (LCIA) data, as well as natural variability in hydrologic data. Uncertainties are analyzed using a robust Monte Carlo simulation approach, performed by High Throughput Computing (HTC) and interpreted by Morse-Scale regression models. The uncertainty analysis platform is applied to a watershed-scale LCA of rainwater harvesting systems (RWH) to control combined sewer overflows (CSOs). To consider the watershed-scale implications, RWH is simulated to serve for both the water supply and CSO control in an urban watershed in Toledo, Ohio, USA. Results suggest that, among the studied parameters, rainfall depth (as a hydrologic parameter) caused more than 86% of the uncertainty, while only 7% of the uncertainty was caused by LCIA parameters. Such an emphasis on the necessity of robust hydrologic data and associated analyses increase the reliability of LCA-based urban water infrastructure design. In addition, results suggest that such a topology-inspired model is capable of rendering an optimal RWH system capacity as a function of annual rainfall depth. Specifically, if the system could capture 1/40th of annual rainfall depth in each event from rooftops, the RWH system would be optimal and, thus, lead to minimized life cycle impacts in terms of global warming potential (GWP) and aquatic eco-toxicity (ETW). This capture depth would be around 2.1 cm for Toledo (given an 85 cm/year rainfall and 200 m2 typical roof area), which could be achieved through an RWH system with 4.25 m3 capacity per household, assuming a uniform plan for the entire studied watershed. Capacities smaller than this suggested optimal value would likely result in loss of RWH potable water treatment savings and CSO control benefits, while capacities larger than the optimal would likely incur an excessive wastewater treatment burden and construction phase impacts of RWH systems.
