Abstract: A basis is provided for selecting a suitable stormwater detention basin design method by identifying the various solution methodologies and by comparing the results. Two design methods, which included hydrologic and hydraulic routing elements, and five planning methods that included only watershed hydrology were applied to watersheds of 50 acres, 200 acres, and 500 acres, and for residential, commercial and industrial land uses. Return periods of 10-yr and 100-yr were used. Based on consideration of model characteristics, one design and one planning method were recommended for providing consistently acceptable results.
