Description :
The aim of the study was to characterize the effects of urban impervious area and associated stormwater runoff on the scaling of stream channel geometry and the associated grain size response with small Inner Coastal Plain watersheds in eastern North Carolina. Urban expansion in the region began in the 1960s, with major urbanization occurring over the last 25 years. Channels draining urban watersheds are still responding to this land use change by downcutting and widening. Urban channel incision has frequently cut off streams from their floodplains, reducing floodplain sediment retention and water quality functions.
