Resumen

The efficiency of phsophogypsum as an amendment for controlling erosion on embankments was studied on a Typic Rhodoxeralf soil, with 48% slope and 10 and 1.5 m long plots, with western and northern aspects and a westerly dominant wind during rainstorms. Phosphogypsum reduced the runoff by 23%, and the erosion was 2-3 times less than on the control slope. The embarkment's aspect has no effect on the amounts of rainfall and runoff, but the erosion from the long plots with a western aspect compared with the long plots with a northern aspect was 1.4 and 2.5 times higher in the control and phosphog

Resumen

Highway runoff is a significant source of contaminants entering many freshwater systems. To provide information on effects of highway runoff on aquatic biota, runoff samples were collected from three sites representing different classes of highways with low, intermediate and high traffic intensities. Samples were analysed for chloride, trace metals and polycyclic aromatic hydrocarbons (PAHs). Runoff from a major multilane divided highway, with the highest traffic intensity, contained the highest levels of chloride (45–19,135 mg/L) and metals. Runoff solids from this highway contained the highe

Resumen

The purpose of this paper is to evaluate the differences between two design alternatives for the pavement edge along the superelevation runoff. The highway literature usually recommends to design the edge as a combination of straight lines, i.e., linear edge design and nonlinear change of superelevation. It is possible, however, to construct another method by which the superelevation increases linearly within the pavement along the runoff. This paper analyzes the two design alternatives and examines the differences between the two methods. It was shown that on a spiralled highway, a linear cha

Resumen

This study analyzed the long-term alterations in runoff regime, seasonality and variability in headwater montane basins in Central Europe in response to the manifestations of climate change. We tested the common hypotheses on climate change effects on surface runoff dynamics in the Central Europe region, assuming that (i) recent climate warming will result in shifts in the seasonality of runoff, (ii) the runoff balance will remain without significant changes and (iii) that higher variability in runoff can be expected. The analyses were done on eight montane catchments in four mid-latitude moun

Resumen

AbstractA low impact development (LID) is an alternative land development approach for managing stormwater that has been recommended instead of the traditional stormwater design. The main purpose of LID is to reduce the impact of development on water related problems through the use of stormwater management practices that infiltrate, evaporate, or harvest and use stormwater on the site where it falls. In recent years, more research has been carried out on the individual practice of LID such as bioretention, pervious pavements, rain garden and grassed swales. Nowadays LID practices have been su

On-site infiltration of a copper roof runoff may contribute to deterioration of the ground and ground water. To avoid such a negative effect the performance of two different technical systems, equipped with four different barrier materials, regarding copper elimination was examined in a field study. During the period March 2004 to January 2005, 16 rain events were examined. Copper concentrations between 200 and 11,000 μg/L in the roof runoff during a rain event were observed. The cover material of the roof and the drainage system were responsible for the high concentrations of copper in the ro

Resumen

The period of high water flow from rivers is a complex phenomenon, which manifests itself in the form of large waters and floods. High flow periods are an important phase in the runoff of rivers, both by their extreme nature and by the effects they can produce on the components of the environment. The paper analyses several aspects related to the periods of water runoff from rivers: genetic factors, frequency, and temporal and spatial parameters of large waters and floods, case studies of the most representative floods, environmental, social and economic effects induced by floods.

Several well-known presenters expressed conflicting views on fundamental issues regarding BMP adequacy and the proper approach to urban runoff quality management. Upon reflection, the author believes that the conflicting opinions result principally from two related facts: 1) there is no accepted uniform design criteria for BMPs, so that various authors are compari

Most neural network hydrological modelling has used split-sample validation to ensure good out-of-sample generalisation and thus safeguard each potential solution against the danger of overfitting. However, given that each sub-set is required to provide a comprehensive and sufficient representation of both environmental inputs and hydrological processes, then to partition the data could create limited individual representations that are, in some manner or other, deficient with respect to fitness-for-purpose.

Abstract This study proposed a method for constructing a low impact development (LID) plan to improve the utilization rate of rainwater in a highway service area and solve the problem of waterlogging. Firstly, based on the theory of LID, taking the total runoff as the control goal, and combining it with the functional zoning of the highway service area and the characteristics of LID facilities, several LID schemes were proposed. Then, the evaluation system of the LID scheme in service area was established by the analytic hierarchy process (AHP). These preliminary construction schemes were comp

The increasing consumption of drinking water puts a heavy burden on our future water resources. Therefore the reuse of rain water in households can be a good option to tackle this problem. On the other hand the rapidly drained rain water leads to problems in the combined sewer systems and watercourses. If the storage in the rain water tanks can be used to flatten the rain water runoff, rain water tanks can have an additional benefit. The effect of rain water tanks on the combined sewer overflow (CSO) emissions is therefore investigated with a reservoir model. Compared with storage in the combi

Resumen

In recent years, China has vigorously promoted the construction of sponge cities and achieved good results. The university campus is a relatively independent existence in the city. Due to historical planning and construction reasons, it is easy to accumulate water when the city has a large amount of precipitation. Taking Wuhan Polytechnic University as an example, this paper analyzes the causes of waterlogging on campus from the aspects of urban precipitation, campus planning, rainwater harvesting and utilization, and proposes a series of low-impact development (LID) measures, such as increasi

Resumen

Torrential floods represent the most frequent phenomenon within the category of ?natural risks? in Serbia. The representative examples are the torrential floods on the experimental watersheds of the rivers Manastirica (June 1996) and Kamisna (May 2007). Hystorical maximal discharges (Qmaxh) were reconstructed by use of ?hydraulics flood traces? method. Computations of maximal discharges (Qmaxc), under hydrological conditions after the restoration of the watersheds, were performed by use of a synthetic unit hydrograph theory and Soil Conservation Service methodology.

Resumen

A key challenge to environmental flow assessment in many rivers is to evaluate how much of the discharge flow should be retained in the river in order to maintain the integrity and valued features of riverine ecosystems. With the increasing impact of climate change and human activities on riverine ecosystems, the natural flow regime paradigm in many rivers has become non-stationary conditions, which is a new challenge to the assessment of environmental flow. This study presents a useful framework to (1) detect change points in runoff time series using two statistical methods (Mann-Kendall test

Resumen

While biofuels have been touted as a benefit for growers—with the ability to be planted on marginal lands, for improved wildlife habitat, to sustain soils, and to reduce runoff—there remains to be a general summary of how beneficial they really are. This paper aims to review the environmental effects, feasibility, and economic aspects of using native perennial grasses in North America as biofuels as opposed to traditional annual crops.

Resumen

AbstractHuman health risks in dealing with floods in a river basin in South-Western Finland are analysed as an example of scientific and practical challenges in systemic adaptation to climate change and in integrated governance of water resources. The analysis is based on case reports and plans, on literature studies and on conceptual models of risks and risk management. Flood risks in the Northern European study area are aggravated by melt- and storm-water runoff, ice jams and coastal flooding. Flood risk assessment is linked with management plans based on EU directives as applied in the case

Resumen

Seawater quality is critical for island and coastal communities dependent on coastal tourism. Improper management of coastal development and inland watersheds can decrease seawater quality and adversely impact marine life, human health, and economic growth. Agricultural runoff and improper sewage management compromise nearshore water quality in many coastal regions and can impact visitation decisions of tourists who are drawn to these destinations. The purpose of this paper is to understand how tourists’ decisions to revisit Barbados might be affected by changes in coastal and marine quality.

Resumen

The implementation of sustainable urban drainage systems (SUDS) is increasing due to their advantages, which transcend runoff control. As a result, it is important to find the appropriate SUDS locations to maximize the benefits for the watershed. This study develops a multiscale methodology for consolidated urban areas that allows the analysis of environmental, social, and economic aspects of SUDS implementation according to multiple objectives (i.e., runoff management, water quality improvements, and amenity generation). This methodology includes three scales: (a) citywide, (b) local, and (c)

Abstract Assessments of the infiltration recharge of groundwater are performed using various methods and on different scales. Infiltration is dependent of climatic factors, aspects of water circulation, as well as on quasi-stationary and variable environmental features of a specific area, which are frequently difficult to determine on the basis of direct measurements or observations. The objective of the present study was to identify factors conditioning recharge of shallow groundwater in selected catchment areas of the Poznań Upland using the WetSpass simulation water balance model with spati

Sustainable stormwater management approaches in accordance with the EU Water Framework Directive (WFD) allow a source control to handle the quality and quantity of the runoff at local level or near the source. The most popular technologies applied in Europe are green roofs, porous pavements, retention basins and bioswales/raingardens. In this article, two of these solutions (retention tank with reuse, and rain garden, respectively), applied to single dwelling case studies in a suburban area in the Silesia Region (Poland), are illustrated and analyzed.
