Abstract: Traditional hydrologic analyses and detention design procedures are too time consuming and costly to be warranted for small projects. This paper discusses a direct solution for sizing a detention basin or for designing the outlet drainage structure, which has been developed and incorporated into a microcomputer program. While the direct solution method can be accomplished by hand, the microcomputer program enables the designer to adapt the solution to the climatological conditions in the specific area of interest, given intensity-duration-frequency curves for rainfall.
