Abstract: Many communities require the use of detention basins in order to manage the increased runoff discharge in all newly developing watersheds. The authors have shown earlier that the typical design criteria for detention basins can cause increased peak discharges from watersheds. In this paper the effect of design rainfall frequency on peak discharges has been reported, and design criteria for detention basins have been proposed to maintain the watershed discharges at peak developed or peak undeveloped discharges.
