WebUrban development also impacts the hydrograph of urban streams (Figure 2). Compared to the pre-development hydrograph, post-development stormwater discharges can increase the runoff volume, increase the peak discharge, and decrease the infiltration of stormwater, which thereby decreases base flow into streams and aquifers. WebTitle: Protecting Water Quality from Urban Runoff Author: US EPA, OW, OWM, Water Permits Division, Municipal Branch Subject: This fact sheet explains how urbanized areas affect water quality through increased runoff and pollutant loads and what homeowners can do to prevent stormwater pollution (EPA 841-F-03-003).
