Abstract:
To develop urban stormwater management effectively, characterization of urban runoff pollution between dissolved and particulate phases was studied by 12 rainfall events monitored for five typical urban catchments. The average event mean concentration (AEMC) of runoff pollutants in different phases was evaluated. The AEMC values of runoff pollutants in different phases from urban roads were higher than the ones from urban roofs. The proportions of total dissolved solids, total dissolved nitrogen, and total dissolved phosphorus in total ones for all the catchments were 26.19%–30.91%, 83.29%–90.

Abstract. This paper addresses the mass balance error observed in runoff hydrographs in urban watersheds by introducing assumptions regarding the contribution of infiltrated rainfall from pervious areas and isolated impervious area (IIA) to the runoff hydrograph. Rainfall infiltrating into pervious areas has been assumed not to contribute to the runoff hydrograph until Hortonian excess rainfall occurs. However, mass balance analysis in an urban watershed indicates that rainfall infiltrated to pervious areas can contribute to direct runoff hydrograph, thereby offering an explanation for the lon

Abstract:
Abstract As a result of changes in social, economic, and political relations, undesirable phenomena are created that have an adverse effect on the urban environment. Surface runoff represents one of several risks to environmental policy, causing the major problem in urban agglomerations. In an urbanized area, it causes an increased runoff volume and the flood peak. Also, it affects increasing the contamination of urban rainwater. The significant problem of surface runoff formation in urban river basins is the accumulation of pollutants on the surface of paved areas during the rainless period.

Abstract To aid urban entities desiring to reduce runoff from precipitation while increasing aquifer recharge, we present an approach for simultaneously quantifying runoff and infiltration. Developing the approach involved using: (1) the Windows version of the Source Loading and Management Model (WINSLAMM) to estimate runoff from precipitation in areas with green infrastructure (GI); and (2) the SCS runoff curve method to estimate infiltration. Computed infiltration and runoff values enable the estimation of the runoff reduction and infiltration increase due to alternative GI construction mode

Abstract:
The change in land use during the process of urbanization affects surface runoff and increases flood risk in big cities. This study investigated the impact of land use change on surface runoff in Beijing’s central area during the period of rapid urbanization from 1984 to 2019. Land use maps of 1984, 1999, 2009, and 2019 were generated by image classification of Landsat images. Surface runoffs were calculated with the Soil Conservation Service curve number (SCS-CN) model. Correlation analysis was used to identify the dominant factor of land use change affecting surface runoff. The result showed

Abstract:
Fecal coliform bacteria (and pathogens), high flow rates, sediment, toxic heavy metals and organic pollutants are most commonly associated with urban receiving water problems. Most beneficial uses have been shown to be adversely affected by urban runoff, including shell fish harvesting, fish and aquatic life propagation, drinking water supplies, aesthetics and recreation. Most of the problems occur over long periods of time and are not associated with individual runoff events, making cause and effect relationships difficult to study.

Abstract:
The interpretation of rain-runoff measurements from 6 small (less than 17 ha) urban catchments is described. The recording period covers mostly 1979-1983. Relations between rain- and runoff depths were developed using the traditional linear regression model as well as a new continuous model. Both models compute runoff from impervious surfaces in the same way. Calculation of runoff from semipervious surfaces accounts for infiltration through cracks, percolation from a sublayer and evaporation during dry weather. These phenomena are related to water content of the sublayer. The 10 parameters in

Abstract:
During periods of rain, combined sewer systems carry urban runoff water to sewage works. Urban runoff water is different, however, from household wastewater — the usual influent of wastewater treatment systems — especially the flow and the concentrations of suspended solids and metals. The purpose of the research described herein was to examine potential effects of runoff water on a treatment system to find out if major damage to the system is likely to result from input of urban runoff. The literature on urban runoff and on qualitative, toxic, quantitative, and hydraulic shocks was reviewed,

Abstract:
Many models have been developed which simulate the quality of runoff from urban impervious areas. Common to these models is the use of exponential accumulation and washoff equations. The two equations have often been calibrated separately by trial and error. However, field data of nonpoint source investigations are usually collected at the watershed outlet or at a few points on impervious surfaces, both of which reflect the combining effects of accumulation in dry weathers and washoff in wet weathers. It is therefore preferable to estimate these parameters simultaneously to obtain the global o
