Design of Stormwater Detention Basins for Multiple Design Frequencies

Abstract

A general planning methodology has been developed for use in the planning of dual‐purpose detention basins. 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. The methodology developed is used to examine two potential strategies for the design of stormwater management facilities for multiple design frequencies. These two strategies are applied to a synthetic watershed constructed from average geomorphic parameters for the state of Indiana.
