Stormwaters, flowing into storm sewers, are known to significantly increase the annual pollutant loads entering urban receiving waters and this results in significant degradation of the receiving water quality. Knowledge of the characteristics of stormwater pollution enables urban planners to incorporate the most appropriate stormwater management strategies to mitigate the effects of stormwater...

Many stormwater management practices depend on sedimentation as their primary removal mechanism, but the settling velocity distribution of particles in runoff from a specific watershed is rarely known. A simple and effective method to characterize settling velocity distribution is needed to improve the design of stormwater management practices. Elutriation devices have been used to characterize...

Decentralized municipal stormwater management, whereby best management practices are dispersed throughout a watershed, are gaining popularity but face unique constraints related to land access and citizen engagement. Decentralized installations require perpetual access to public and private land, a constraint that may be solved creatively in many urban settings through the repurposing of vacant...

The traditional management of stormwater with a singular focus on flood protection has resulted in the degradation of receiving waters. The health of urban streams is degraded by a suite of stressors, notably, the frequent disturbance due to stormwater runoff. We investigate the catchment scale implications of allotment scale rainwater harvesting, in terms of potential simultaneous benefits for...

Catchment urbanisation leads to increased hydraulic and pollutant loadings into receiving waterbodies. Issues concerning pollution that endangers the sustainable utilisation of water resources have focused government authorities towards integrated catchment management, where both causes and effects of pollution are addressed. Recent research has provided a platform for improving urban stormwate...

Inorganic chemicals in urban stormwater and snowmelt runoff originate from catchment geology and anthropogenic activities. The occurrence, partitioning and mobility of six minerals and six trace metal (TM) indicators of anthropogenic activities were studied in stormwater, snowmelt and baseflow in four urban catchments, and the sampling of inorganics was supplemented by measurements of electrica...

Urban stormwater runoff is being recognized as a major source of pollutants to receiving waters and a number of recent investigations have evaluated stormwater runoff quality and best management practices to minimize pollutant input to receiving waters. Particle-bound contaminants are widespread in the urban environment causing impairment to urban water bodies such as streams and lakes. Non-poi...

Stormwater pollution has become an area of major concern in the United States. Stormwater has a different origin and behavior than other polluted waters; therefore, analyzing pollutants loads is critical in design and management of stormwater systems. The objective of this study was to characterize stormwater suspended-sediments concentrations (SSC) into a closed-basin system during rainfall-ru...

Decentralized stormwater management approaches (e.g., biofiltration swales, pervious pavement, green roofs, rain gardens) that capture, detain, infiltrate, and filter runoff are now commonly used to minimize the impacts of stormwater runoff from impervious surfaces on aquatic ecosystems. However, there is little research on the effectiveness of retrofit, parcel-scale stormwater management pract...

Climate changes, failure to complete the natural cycle of water in the city due to unsustainableconstruction of the urban environments and increase of impervious surfaces, lack of nutrition of undergroundaquifer in the cities, unsustainable management of stormwater and the floods due to them in the periods of rainfallcaused to provide an approach that is called water sensitive urban design.
