Effects of urban stormwater-management strategies on stream-water quantity and quality

Abstract

Urbanization results in elevated stormwater runoff, greater and more intense streamflow, and increased delivery of pollutants to local streams and downstream aquatic systems such as the Chesapeake Bay. Stormwater Best Management Practices (BMPs) are used to mitigate these effects of urban land use by retaining large volumes of stormwater runoff (water quantity) and removing pollutants in the runoff (water quality). Current USGS research aims to understand how the spatial pattern and connectivity of stormwater BMPs affect water quantity and water quality in urban areas.
