Abstract:

Based on the analysis of the current state of water resources and utilization characters, the optimizing and allocating model of water resources in Yinchuan plain is established by multi-objective planning methodology. Systematic viewpoint runs throughout the whole modeling process. Furthermore, by employing the established model, the proper allocation of the industrial and agricultural water, the ecological environment water and integrated development of surface water and groundwater are discussed. The more reasonable water utilization structure is suggested. The water resource for agriculture is decreasing, while the water resource for people life, industry and ecologic environment are increasing. This change of water utilization is correspond to economic and social development trend.

Abstract:

Watershed management increasingly requires ecohydraulic modeling and assessment within a regional context, rather than on a project-by-project basis. Such holistic modeling and assessment require evaluation capabilities across multiple temporal and spatial scales. Thus, modeling and assessment tools must be integrated in a scientifically and computationally effective infrastructure. The US Army Engineer Research and Development Center, in concert with the Hydrologic Engineering Center and its academic partners, including Brigham Young University, is establishing a comprehensive set of hydroinformatics modeling and assessment tools for ecohydraulic and water resources management applications, all linked based on a common data and information infrastructure. This paper presents the attributes of this information infrastructure and compares it with the analogous integration initiatives elsewhere.

Abstract:

Some management information databases (MIBS) have been developed in recent years to help the water resource managers with more effective and fast work. Yet few integrated models of water resources management can be observed so far. This paper discussed and designed the Integrated Water Resources Management Information Database (IWRMI-Database) for Changzhi City, Shanxi Province. In this database, the requirements of water-use statistics, water intake permission and levy on water resources were studied in detail, the data which play a decisive role in management were analyzed, and the concept and physical models of the database were built with the modeling tool, Sybase Power Designer, which greatly saved the development time.

Abstract:

Mathematical models have been developed for managing the water resources of the Ingulets River in accordance with the requirements of the EU Water Framework Directive on the establishment of cost-effective water use with ensuring good or excellent ecological river status. The structural and functional diagram of the system model includes the subsystems: water supply by the Dnipro-Ingulets canal; flushing the Ingulets River from the Karachunivske reservoir and displacing the saline prism into the Dnipro River; environmental safety when discharging pollution into the river Ingulets; water supply for irrigation in the Ingulets irrigation system, prevention of soil salinization. Integrated management is carried out by subsystems, by types of management and by a system of criteria. A system of economic and environmental criteria for evaluating integrated management by the basin principle has been developed. Simulation of scenarios based on operational management is carried out. Scenarios are optimized according to the Pareto principle. An example of evaluating the effectiveness of the proposed control system and its comparison with the existing regulations for flushing the Ingulets River is given.

Abstract. Integrated Water Resources Management (IWRM) recommends, among other things, that the management of water resources systems be carried out at the lowest appropriate level in order to increase the transparency, acceptability and efficiency of the decision-making process. Empowering water users and stakeholders transforms the decision-making process by enlarging the number of point of views that must be considered as well as the set of rules through which decisions are taken. This paper investigates the impact of different group decision-making approaches on the operating policies of a water resource. To achieve this, the water resource allocation problem is formulated as an optimization problem which seeks to maximize the aggregated satisfaction of various water users corresponding to different approaches to collective choice, namely the utilitarian and the egalitarian ones. The optimal operating policies are then used in simulation and compared. The concepts are illustrated with a multipurpose reservoir in Chile. The analysis of simulation results reveals that if this reservoir were to be managed by its water users, both approaches to collective choice would yield significantly different operating policies. The paper concludes that the transfer of management to water users must be carefully implemented if a reasonable trade-off between equity and efficiency is to be achieved.

Abstract:

Anthropogenic and natural disturbances to freshwater quantity and quality is a greater issue for society than ever before. To successfully restore water resources in impaired watersheds requires understanding the interactions between hydrology, climate, land use, water quality, ecology, social and economic pressures. Current understanding of these interactions is limited primarily by a lack of innovation, investment, and interdisciplinary collaboration. This Special Issue of Water includes 18 articles broadly addressing investigative areas related to experimental study designs and modeling (n = 8), freshwater pollutants of concern (n = 7), and human dimensions of water use and management (n = 3). Results demonstrate the immense, globally transferable value of the experimental watershed approach, the relevance and critical importance of current integrated studies of pollutants of concern, and the imperative to include human sociological and economic processes in water resources investigations. Study results encourage cooperation, trust and innovation, between watershed stakeholders to reach common goals to improve and sustain the resource. The publications in this Special Issue are substantial; however, managers remain insufficiently informed to make best water resource decisions amidst combined influences of land use change, rapid ongoing human population growth, and changing environmental conditions. There is thus, a persistent need for further advancements in integrated and interdisciplinary research to improve scientific understanding, management and future sustainability of water resources.

Abstract:

Urbanization and population growth increase the demand for freshwater abstraction, food production, rising thus the agricultural, economic, and productivity expectations. The need for improved water services, sustainable and resilient management under changing climate, are major drivers to set forth the redesigning of water planning. Water scarcity combined with the limited expansion of new infrastructure create competition among water uses and further stress the satisfactory coverage of the increasing needs. Integrated modeling is a way to simulate and address the above challenges, however, poor monitoring, incomplete databases, and complexity make its applications difficult. Questions such as what data to use, how to best exploit the (limited) available databases, what parameters to calculate, and how to satisfy both economic and environmental objectives, occur. This study presents a novel Decision Support System (DSS), combining hydrology, economics, engineering, and social aspects, aimed to participatory management, using simple concepts, and discussing assumptions for working with limited data, and useful parameters to estimate. Water availability and demand, water quality, profits, costs, and management scenario analysis, including nature-based solutions, are explored under climate change scenarios, and alternative policies are evaluated. The combination of the above and the useful modeling insights, under water- and data-scarcity conditions are novel elements, while the aim is to encourage integrated and sustainable water resources management through understandable and user-friendly DSSs.

Abstract:

Water shortages from intermittent public supplies are a major and expanding problem in the Hashemite Kingdom of Jordan. Yet individual users, utility managers, and government officials can improve access or cope with shortages in many ways. New supplies, more efficient use of existing resources, long-term investments to expand infrastructure and reduce leakage, and short-term measures to flexibly transfer, ration, or curtail some uses represent several different approaches for management. This paper reviews three separate systems analysis that use stochastic optimization with recourse. Analysis for individual residential users, the water utility serving 2.2 million residents in the capital Amman, and the entire kingdom comprising Amman and 11 other governorates identify complementary actions to be undertaken by individual users, utility managers, and government officials.

Abstract:

Research has largely been driven by the quest for innovation, new knowledge and improving the general wellbeing of the human race. Monumental challenges that plague humanity tend to, from time to time, shape research and take it to new heights, and one of such is the global water crisis [1,2]. To restate the obvious that water is the basis of life and the engine for social and economic growth, water resource engineering research attempts to address challenges related to: (i) how water of sufficient quantity and quality can be made available to meet various competing sectoral demands; (ii) how development and exploitation of the resource can be carried out in a sustainable manner so that its benefits extend to future generations; (iii) what adaptation and mitigating measures can be put in place to minimize the impacts of global climate change. This paper, therefore, presents trends in four areas of research in water resources engineering that focus on the paradigm shifts in water supply and sanitation, integrated modeling in order to give quantitative expression to integrated water resources management (IWRM), thereby achieving a more defined space for decision making, new and emerging cost-effective water treatment technologies, and research developments in adaptation measures to climate change.

Abstract:

Zhangweinan basin is a typical area where has the most serious water resource shortage and water environmental deterioration problems in north of China. To improve the increasingly deteriorated water eco-environment, studies on the integrated management of water resources and water environment in the basin were carried out with focus on the prevention and control of water pollution, and based on which, an integrated management platform on water environment was developed. This paper introduces the platform architecture and elaborates the construction process of the total pollutant load control model and pollution incident early warning model. This platform provides technical supports for weakening the total pollutant load in the basin, reducing the pollutant load flowing into the Bohai Sea, and increasing the eco-flow of river channel and flow into the Bohai Sea.

Abstract:

To maintain sustainability and availability of regional water resources, appropriate integrated water resource management (IWRM) should be based on an assessment of water resource background and responses to regional development and utilization policies. The study proposed an assessment method combining hydrological variation analysis with a system dynamics (SD) model to support IWRM in the Baiyangdian Region, Northern China. Integrated variation analysis and attributive analysis were used to identify variation time and causes of runoff. Then, based on the current water resource situation, an accessibility analysis examined the possibility of achieving a water resources supply and demand balance of social economic development and the ecological environment within individual internal management. Finally, an SD model simulated water resource response to development policies to predict future policy impacts. Results showed that 65.18% of the impact on runoff was from human activities. Sustainability goals were impossible through internal management, but with eco-migration policies and 1 × 108 m3 inter-basin transferred water, it could quickly be achieved, and water ecosystem function could also be recovered. Establishment of the Xiong’an New Area necessitated introduction of integrated cross-basin management to protect the Baiyangdian Region from degradation of its ecological function. Our study proposed a new method for comparation of internal and cross-basin IWRM.

Abstract:

Some of the world's most valuable aquatic ecosystems such as deltas, lagoons and estuaries are located in the coastal zone. However, the coastal zone and its aquatic ecosystems are in many places under environmental stress from human activities. About 50% of the human population lives within 200 km of the coastline, and the population density is increasing every day. In addition, the majority of urban centres are located in the coastal zone. It is commonly known that there are important linkages between the activities in the upstream river basins and the environment conditions in the downstream coastal zones. Changes in river flows, e.g. caused by irrigation, hydropower and water supply, have changed salinity in estuaries and lagoons. Land use changes, such as intensified agricultural activities and urban and industrial development, cause increasing loads of nutrients and a variety of chemicals resulting in considerable adverse impacts in the coastal zones. It is recognised that the solution to such problems calls for an integrated approach. Therefore, the terms Integrated Water Resources Management (IWRM) and Integrated Coastal Zone Management (ICZM) are increasingly in focus on the international agenda. Unfortunately, the concepts of IWRM and ICZM are mostly being developed independently from each other by separate management bodies using their own individual approaches and tools. The present paper describes how modelling tools can be used to link IWRM and ICZM. It draws a line from the traditional sectoral use of models for the Istanbul Master Planning and assessment of the water quality and ecological impact in the Bosphorus Strait and the Black Sea 10 years ago, to the most recent use of models in a Water Framework Directive (WFD) context for one of the selected Pilot River Basins in Denmark used for testing of the WFD Guidance Documents.

Abstract:

Hydro-economic modeling is the combination of economic principles and hydrological modeling to achieve a more integrated representation of water resource management. In the Murray–Darling Basin (MDB), hydro-economic modeling has been widely used to analyze and inform basin-wide water policy. A growing but uneven literature base has prompted this review of MDB hydro-economic studies published over the past three decades to identify innovations and avenues for advancement. We focus particularly on the treatment of uncertainty, which is inherent in all modeling. While consideration of uncertainty is increasing in prominence, our review indicates the robust treatment of epistemic and stochastic uncertainty have not been fully integrated in the hydro-economic modeling literature. When hydro-economic modeling results are used to inform policy, treatment of uncertainty has both technical and political implications. We conclude that the methodological rigor of MDB hydro-economic modeling can be vastly improved with greater attention to quantifying, reducing and communicating uncertainties inherent in the modeling of water resources.

Abstract:

The development of adequate modeling at the basin level to establish public policies has an important role in managing water resources. Hydro-economic models can measure the economic effects of structural and non-structural measures, land and water management, ecosystem services and development needs. Motivated by the need of improving water allocation using economic criteria, in this study, a Spatial Decision Support System (SDSS) with a hydro-economic optimization model (HEAL system) was developed and used for the identification and analysis of an optimal economic allocation of water resources in a case study: the sub-middle basin of the São Francisco River in Brazil. The developed SDSS (HEAL system) made the economically optimum allocation available to analyze water allocation conflicts and trade-offs. With the aim of providing a tool for integrated economic-hydrological modeling, not only for researchers but also for decision-makers and stakeholders, the HEAL system can support decision-making on the design of regulatory and economic management instruments in practice. The case study results showed, for example, that the marginal benefit function obtained for inter-basin water transfer, can contribute for supporting the design of water pricing and water transfer decisions, during periods of water scarcity, for the well-being in both basins.

Abstract:

This study presents an integrated modeling system for the evaluation of the quantity and quality of water resources of coastal agricultural watersheds. The modeling system consists of coupled and interrelated models, including (i) a surface hydrology model (UTHBAL), (ii) a groundwater hydrology model (MODFLOW), (iii) a crop growth/nitrate leaching model (REPIC, an R-ArcGIS-based EPIC model), (iv) a groundwater contaminant transport model (MT3DMS), and (v) a groundwater seawater intrusion model (SEAWAT). The efficacy of the modeling system to simulate the quantity and quality of water resources has been applied to the Almyros basin in Thessaly, Greece. It is a coastal agricultural basin with irrigated and intensified agriculture facing serious groundwater problems, such as groundwater depletion, nitrate pollution, and seawater intrusion. Irrigation demands were estimated for the main crops cultivated in the area, based on precipitation and temperature from regional weather stations. The models have been calibrated and validated against time-series of observed crop yields, groundwater table observations, and observed concentrations of nitrates and chlorides. The results indicate that the modeling system simulates the water resources quantity and quality with increased accuracy. The proposed modeling system could be used as a tool for the simulation of water resources management and climate change scenarios.

Abstract:

Integrated water resources management at the catchment scale, considering the full water cycle as manageable, is a primary approach to improve water use efficiency and promote sustainable water management solutions. To this purpose, advanced modelling tools are required to quantify the physical and economic effects of alternative land management options. This work presents an application of a spatially distributed physically based hydrological model to the Bonis experimental watershed located in the mountain area of Sila Greca (southern Italy). Different infiltration models were tested to better reproduce discharge observations at basin outlet. The model will be used for evaluating different land use/management scenarios, combined with climate change forcing, to quantify the effect of alternative management options on the land-water cycle. This work is part of the INNOMED project (Innovative Options for Integrated Water Resources Management in the Mediterranean) funded by ERA-NET COFUND WATERWORKS 2015 call.

Abstract:

In this paper the integration of water resources management with regard to reservoir management in an eco-hydrological model is described. The model was designed to simulate different reservoir management options, such as optimized hydropower production, irrigation intake from the reservoir or optimized provisioning downstream. The integrated model can be used to investigate the impacts of climate variability/change on discharge or to study possible adaptation strategies in terms of reservoir management. The study area, the Upper Niger Basin located in the West African Sahel, is characterized by a monsoon-type climate. Rainfall and discharge regime are subject to strong seasonality. Measured data from a reservoir are used to show that the reservoir model and the integrated management options can be used to simulate the regulation of this reservoir. The inflow into the reservoir and the discharge downstream of the reservoir are quite distinctive, which points out the importance of the inclusion of water resources management.

Abstract:

For integrated water management in river basins in Ukraine, there is no toolkit for system modeling and selection of management structure in river basins according to environmental and economic criteria, which corresponds to the creation of water management systems under conditions of sustainable development. Therefore, the urgent task is to develop a system model of integrated water management on the example of the Ingulets River basin. The purpose of the work is to create a system model of integrated water resources management in Ingulets River basin, which provides scenario modeling of technological solutions, their evaluation and optimization of economic criteria for efficient water use under environmental constraints and criteria for achieving a good or excellent ecological status of the river basin. The system model is used as a toolkit, the method of decomposition of the river basin into subsystems, analysis of subsystems and their composition into a holistic model of integrated management by the basin principle. Telecommunication methods are proposed to improve monitoring. A method of scenario analysis is proposed, which performs simulation modeling of prospective management scenarios at the first level of the hierarchy, and at the second level - options are evaluated according to the criteria of cost-effective water use with environmental objectives and regulatory restrictions. For simulation modeling, a system of balance difference equations for the dynamics of water masses, mixing and spreading of pollution in rivers and reservoirs is formalized. A system of combined control for the impulse method of river washing was developed. Multicriteria optimization of variants of the control structure is carried out on the Pareto principle. A system model has been developed for integrated water resources management in the Ingulets River basin that meets the requirements of the EU Water Framework Directive on the establishment of cost-effective water use while ensuring good or excellent ecological status of rivers. The structural and functional diagram of the system model includes the subsystems: the water supply subsystem of the Dnipro-Ingulets canal; a subsystem for flushing the Ingulets River from the Karachunivske reservoir and displacing the saline prism into the Dnipro River; subsystem of environmental safety when discharging pollution into the river Ingulets; subsystem of water supply for irrigation in the Ingulets irrigation system, prevention of soil salinization. A system of technological, economic and environmental criteria for evaluating integrated management by the basin principle has been developed. They include maintaining the water level in reservoirs, displacement of salt water prism and limitation on water quality, ensuring the ecological condition of the river, and the dynamics of water resources consumption. Technological criteria determine the maintenance of water levels in reservoirs. Cost-effective water use is estimated on the basis of the dynamics of water consumption for river washing and irrigation. The formalized integrated management system in the Ingulets River basin includes operational water resources management and structure management. Integrated management is carried out according to subsystems, types of management and a system of criteria. For operational management the balance differential equations of water exchange in reservoirs are formalized. A two-layer model of water masses dynamics, pollutants distribution and mixing when flushing rivers from reservoirs is used. Scenario analysis is offered to select the optimal structure of the management system. Simulation scenarios are being simulated. Scenario optimization is performed on the Pareto principle. An example of evaluating the effectiveness of the proposed system and its comparison with the existing regulations for Ingulets River flushing is given.

Abstract:

Changes in land use and land cover can have many drivers, including population growth, urbanization, agriculture, demand for food, evolution of socio-economic structure, policy regulations, and climate variability. The impacts of these changes on water resources range from changes in water availability (due to changes in losses of water to evapotranspiration and recharge) to degradation of water quality (increased erosion, salinity, chemical loadings, and pathogens). The impacts are manifested through complex hydro-bio-geo-climate characteristics, which underscore the need for integrated scientific approaches to understand the impacts of landscape change on water resources. Several techniques, such as field studies, long-term monitoring, remote sensing technologies, and advanced modeling studies have been contributing to better understanding the modes and mechanisms by which landscape changes impact water resources. Such research studies can help unlock the complex interconnected influences of landscape on water resources for quantity and quality at multiple spatial and temporal scales. In this Special Issue, we published a set of eight peer-reviewed articles elaborating on some of the specific topics of landscape changes and associated impacts on water resources.

Abstract:

Water in Nepal is a key strategic natural resource, which has the potential to lead the all round development and economic growth of the country. Integrated Water Resource Management (IWRM) is a holistic management approach, integrating land water interaction, socio economic groups, upstream downstream relations, indigenous knowledge, and institutions built up, along the temporal dimensions based on an agreed set of principles. It is a bottom-up decentralized approach for the management of water resources. IWRM is a challenge to conventional practices, attitudes and professional certainties. It confronts entrenched sectoral interest & requires that the water resources are managed holistically for the benefits of all.The broad objective of the multidisciplinary study was to assess the possibilities of Human Dimensions of water resource development and its management. Water resource accounting is done by the collection of water resources data through participatory group formation. Scientific data of hydro and metrological stations was also acquired. Hydrological modeling tools were also used. Feasibility of hydropower plant and potential of power production in the basin was readily estimated.Total daily discharge of the Durlung Watershed was estimated on an average of 157 Million Liters. Rivers of the watershed are turbulent, unsteady & flowing with very high current, which can be utilized by local people for low cost drinking water, tourism, irrigation & hydropower generation. Micro-hydropower production possibilities in Ratan and Deuta rivers have shown multidimensional positive impacts on socio-economic development of the region. Level of community partnership in IWRM and synchronization with the local, district & national level institutional framework for Basin Management was observed to be satisfactory. Participatory research was carried to identify water resource base with school & community partnership. Community motives, their difficulties and gaps in community level organization were identified. For capabilities of community to take over the responsibilities of IWRM concept, there is a lot more need of training and capacity building for now.

Abstract:

Increasing human demands for water, energy, food and materials, are expected to accentuate resource supply challenges over the coming decades. Experience suggests that long-term strategies for a single sector could yield both trade-offs and synergies for other sectors. Thus, long-term transition pathways for linked resource systems should be informed using nexus approaches. Global integrated assessment models can represent the synergies and trade-offs inherent in the exploitation of water, energy and land (WEL) resources, including the impacts of international trade and climate policies. In this study, we review the current state-of-the-science in global integrated assessment modeling with an emphasis on how models have incorporated integrated WEL solutions. A large-scale assessment of the relevant literature was performed using online databases and structured keyword search queries. The results point to the following main opportunities for future research and model development: (1) improving the temporal and spatial resolution of economic models for the energy and water sectors; (2) balancing energy and land requirements across sectors; (3) integrated representation of the role of distribution infrastructure in alleviating resource challenges; (4) modeling of solution impacts on downstream environmental quality; (5) improved representation of the implementation challenges stemming from regional financial and institutional capacity; (6) enabling dynamic multi-sectoral vulnerability and adaptation needs assessment; and (7) the development of fully-coupled assessment frameworks based on consistent, scalable, and regionally-transferable platforms. Improved database management and computational power are needed to address many of these modeling challenges at a global-scale.

Abstract:

Integrated Water Resource Management (IWRM) aims at finding practical and sustainable solutions to water resource issues. Research and practice have shown that innovative methods and tools are not sufficient to implement IWRM – the concept needs to also be integrated in prevailing management paradigms and institutions. Water governance science addresses this human dimension by focusing on the analysis of regulatory processes that influence the behavior of actors in water management systems. This paper proposes a new methodology for the integrated analysis of water resources management and governance systems in order to elicit and analyze case-specific management paradigms. It builds on the Management and Transition Framework (MTF) that allows for the examination of structures and processes underlying water management and governance. The new methodology presented in this paper combines participatory modeling and analysis of the governance system by using the MTF to investigate case-specific management paradigms. The linking of participatory modeling and research on complex management and governance systems allows for the transfer of knowledge between scientific, policy, engineering and local communities. In this way, the proposed methodology facilitates assessment and implementation of transformation processes towards IWRM that require also the adoption of adaptive management principles. A case study on flood management in the Tisza River Basin in Hungary is provided to illustrate the application of the proposed methodology.

Abstract. One of the innovative objectives in the EC project BRAHMATWINN was the development of a stakeholder oriented Integrated Water Resources Management System (IWRMS). The toolset integrates the findings of the project and presents it in a user friendly way for decision support in sustainable integrated water resources management (IWRM) in river basins. IWRMS is a framework, which integrates different types of basin information and which supports the development of IWRM options for climate change mitigation. It is based on the River Basin Information System (RBIS) data models and delivers a graphical user interface for stakeholders. A special interface was developed for the integration of the enhanced DANUBIA model input and the NetSyMod model with its Mulino decision support system (mulino mDss) component. The web based IWRMS contains and combines different types of data and methods to provide river basin data and information for decision support. IWRMS is based on a three tier software framework which uses (i) html/javascript at the client tier, (ii) PHP programming language to realize the application tier, and (iii) a postgresql/postgis database tier to manage and storage all data, except the DANUBIA modelling raw data, which are file based and registered in the database tier. All three tiers can reside on one or different computers and are adapted to the local hardware infrastructure. IWRMS as well as RBIS are based on Open Source Software (OSS) components and flexible and time saving access to that database is guaranteed by web-based interfaces for data visualization and retrieval. The IWRMS is accessible via the BRAHMATWINN homepage: http://www.brahmatwinn.uni-jena.de and a user manual for the RBIS is available for download as well.

Abstract:

Water is a key driver for socio-economic development, livelihoods and ecosystem integrity. This is reflected in the emergence of unified paradigms such as Integrated Water Resource Management (IWRM) and the weight accorded to it in the Sustainable Development Goals agenda. This paper interrogated the effectiveness of existing participatory planning and assessment models adapted from IWRM model on water quality and public health at community level. The analysis was built around public health ecology perspective and drew useful lessons from critique of basin wide integrated Modeling approaches and existing community participatory models envisaged under Water Users Associations (WUA) in South Africa. We extended the use of political ecology lenses to ecological public health through use of communication for development approaches, to argue that public health risk reduction and resilience building in community water projects require the use of innovative analytical and conceptual lenses that unbundle cognitive biases and failures, as well as, integrate and transform individual and collective agency. The study concludes that the inherent “passive participation” adapted from IWRM model fail to adequately address water quality and public health dimensions in its pillars. Since water quality has direct bearing on disaster risks in public health, building a coherent mitigatory vision requires the adoption of active participatory assessment and planning models that incorporate livelihoods, agency, social learning dynamics and resilience through recognition of communication for development approaches in community empowerment.

Abstract:

Groundwater quantity and quality degradation by agricultural practices is recorded as one of the most critical issues worldwide. This is explained by the fact that groundwater is an important component of the hydrological cycle, since it is a source of natural enrichment for rivers, lakes, and wetlands and constitutes the main source of potable water. The need of aquifers simulation, taking into account water resources components at watershed level, is imperative for the choice of appropriate restoration management practices. An integrated water resources modeling approach, using hydrological modeling tools, is presented for assessing the nitrate fate and transport on an over-exploited aquifer with intensive and extensive agricultural activity under various operational strategies and future climate change scenarios. The results indicate that climate change affects nitrates concentration in groundwater, which is likely to be increased due to the depletion of the groundwater table and the decrease of groundwater enrichment in the future water balance. Application of operational agricultural management practices with the construction and use of water storage infrastructure tend to compensate the groundwater resources degradation due to climate change impacts.

Abstract:

The purpose of this study is to compare the forecasting efficiency of two univariate time series models, the seasonal autoregressive integrated moving average (SARIMA) and the Holt-Winter’s triple exponential smoothing. A monthly electricity and water consumption data used was sourced from the South African Reserve Bank. This data was available for the period Q3 2008 to Q1 2016. Upon subjecting the data to the diagnostic tests of normality, heteroscedasticity and stationarity, parameters of the selected model were estimated using the maximum likelihood method. Although the two models were found to be good estimators and globally significant, Holt Winter’s triple exponential smoothing (HWTES) was selected as the best forecasting model based on the small forecast errors generated. The forecasts revealed that utility resources demand in South Africa are expected to be high for the period 2016 to 2017 and the trend extends to periods ahead. Using these findings, better strategies on the production and distribution of electricity and water can be formulated. Lives of people in South Africa could also be improved.

Abstract:

Abstract The water resources management in the developing countries calls for the adoption of the systems approach in accordance with the regulations of the Kyoto Protocol (1997) clean development mechanism. In this research, integrated modeling was carried out under multipurpose scenarios using six reservoir dams with a capacity of 10,500 MW (megawatt) to reduce the greenhouse gas productions. The simulation and development of the integrated water evaluation and planning (WEAP) model within a 50-year period, along with the development of the MODFLOW model in alluvial deposits that interacts with the river, allowed for the analysis of the integrated water resources management system of the Great Karun basin. Several scenarios were implemented following the calibration and validation of the linked integrated model. The components covered by these scenarios included the satisfaction of the in-basin and off-basin demands, the effect of the integrated consumption of water resources, and the effect of increased efficiency of irrigation networks with maximum clean hydroelectricity production and minimum aquifer level decline under drought-induced water shortage conditions. The second scenario, which generates 15,282 GWh (gigawatt-hour) of power, not only optimally meets the future and environmental demands as the best operating scenario but also minimizes the emission of the greenhouse gases in the basin.

Abstract:

Population growth, rapid urbanization, changing diets, and economic development are among the major driving factors of increased demand for water, food and land. In this study, an integrated model was developed for managing land-water-food nexus. A water footprint-based fuzzy fractional programming (WFFP) is developed for optimizing resource allocations toward sustainable food and water security under the agricultural, food, socioeconomic, and natural resource constraints. By calculating the blue and green water footprint of each crop, optimum food requirements were converted into optimal cropping options. The WFFP method can tackle ratio optimization problems associated with fuzzy information, in which fuzzy possibilistic programming is integrated into a linear fractional programming framework. The method is applied to a case study of the Three (Yangtze-Yellow-Lantsang) Rivers Headwaters Region of China. The results can provide the basis for water and agricultural policies formulation and land-water-food nexus management in the study region.

Abstract:

Ensuring future drinking water supply requires a tough management of groundwater resources. However, recent practice of economic resource control often does not involve aspects of the hydrogeochemical and geohydraulical groundwater system. In respect of analysing the available quantity and quality of future raw water, an effective resource management requires a full understanding of the hydrogeochemical and geohydraulical processes within the aquifer. For example, the knowledge of raw water quality development with time helps to work out strategies of water treatment as well as planning finance resources. On the other hand, the effectiveness of planned measurements reducing the infiltration of harmful substances such as nitrate can be checked and optimized by using hydrogeochemical modelling. Thus, within the framework of the InnoNet program funded by Federal Ministry of Economics and Technology, a network of research institutes and water suppliers work in close cooperation developing a planning and management tool particularly oriented on water management problems. The tool involves an innovative material flux model that calculates the hydrogeochemical processes under consideration of the dynamics in agricultural land use. The program integrated graphical data evaluation is aligned on the needs of water suppliers.
