A Comparative Application of Several Methods for the Design of Storm Sewers

摘要

Four methods which may be employed in the design and analysis of urban drainage systems were investigated: the National method, the Illinois Urban Drainage Area Simulator (ILLUDAS), the Soil Conservation Curve Number Method (CN) and the instantaneous unit hydrograph of Sarma, Delleur, and Rao (SDR). These methods were applied to two subdivisions: Fair Oaks Estates located in Carol Stream, Illinois, and Bar Berry Heights in West Lafayette, Indiana. Recommendations for the most effective use of each method are presented.
