Abstract: Storm-water runoff entering filters is usually aerobic and therefore the removal processes in the filter normally occur under oxidizing and aerobic conditions. However, storm-water filters differ from water and wastewater ...

Abstract: As more manufactured stormwater treatment devices enter the market, stormwater managers are searching for effective and rapid methods for evaluating device performance. Many agencies require vendors to test full-scale ...

Abstract: Most of the literature dealing with hydrologic frequency analysis treats data as being exact and error free. This paper demonstrates that the use of common estimators for distribution parameters and quantiles can lead to ...

Abstract: Storm-water filters and biofilters are limited by physical clogging. Several models have been proposed to predict the flow rate through the media throughout its lifespan. Urbonas (1999) modeled flow rate through a downflow ...

Abstract: One aspect of integrated watershed management evaluates the impact of development on the local hydrologic cycle and, in particular, drinking water, wastewater, and storm-water infrastructure. Sustainable storm-water ...

Abstract: The ability of catchbasin sumps and hydrodynamic separators to remove sediment must be balanced with their ability to retain the previously captured material by preventing scour. The sediment scour process in these storm-water ...

Abstract: During urbanization, undisturbed land surfaces are altered to create manufactured landscapes. Classifications of these new urban surfaces are utilized in urban planning, environmental monitoring, and other applications ...

Abstract: This article describes the results of a series of research tasks to develop a procedure to investigate non‐storm‐water (dry‐weather) entries into storm‐drainage systems (Pitt et al. 1993a, 1993b). Dry‐weather flows discharging ...

Abstract: Grass swales, originally used for erosion control in agricultural settings, are now widely employed in urban environments as an effective best management practice for controlling pollutants in stormwater runoff. In particular, ...

Abstract: Soil infiltration is a critical component of most urban runoff models. However, it has been well documented that, during urbanization, soils are greatly modified, especially in relation to soil density. Increased soil ...
