Climate Change and Watershed Hydrology—Heavier Precipitation Influence on Stormwater Runoff

Authors: Anne C. Blair and Denise Sanger

Abstract Excerpt: Stormwater runoff in the USA is a main driver of non-point source pollution and other major problems for urbanizing areas, and runoff effects will be exacerbated by the increased frequency and intensity of heavier storm events that are projected as climate changes. The purpose of this paper is to consider how increased rainfall from storms could influence direct stormwater runoff in urbanizing watersheds.
