Development of a General Planning Methodology for Storm Water Management in Urban Watersheds

摘要

A new methodology is developed for use in the planning of dual purpose detention basins in urban watersheds. The methodology employs continuous simulation, statistical analysis, and a general design heuristic to obtain an integrated system of detention basins. Both water quantity and water quality constraints may be considered. Several different approaches were considered in the development of the design heuristic. The developed methodology uses a dynamic program to obtain a feasible starting point for a nonlinear search algorithm. The nonlinear search algorithm employs the Complex Method of Box. The general planning methodology was applied to an actual watershed in Glen Ellyn, Illinois, and to a synthetic watershed that was constructed from average geomorphic data for the state of Indiana.
