Hydrologic Disturbance and Response of Aquatic Biota in Big Darby Creek Basin,Ohio

摘要

This report describes the effects of storm runoff and associated physicaldisturbances on stream biota in the Big Darby Creek Basin. Hydrologic conditions and habitat disturbances in a stream benthic community were investigated at the three study sites from April 1994 through September 1994. Related factors, such as streambed-sediment particle-size distribution, antecedent streamflow, and biotic interactions are discussed in terms of the washout and recovery of macro-invertebrates and algae.
