EFFECTS OF URBANIZATION OF CHANNEL INSTABILITY

摘要

Channel instability and aquatic ecosystem degrada- tion have been linked to watershed imperviousness in humid regions of the U.S. In an effort to provide a more process-based linkage between observed thresholds of aquatic ecosystem degrada- tiona and urbanization, standard single event approaches(U.S. Geo- logical Survey Flood Regression Equations and rational)and continuous hydrological in flow regime associated with varying levels of watershed imperviousness.
