![]() ![]() Small storm hydrology features have been defined and studied for the past 20 y (Pitt, 1987 1999a) to examine the specific elements that should be taken into account for the design of BMPs used for recharge, quality and erosion control. ![]() The best management practices (BMPs) and low impact development (LID) techniques that are specifically designed to reduce these impacts generally consider small to moderate rainfall events and the hydrologic modeling of these events is in some respect different from the modeling for the larger storms that are typically used in control of peak flowrates. Stormwater management practices increasingly are required to meet not only peak flowrate restrictions but also are required to include measures that can minimize the impacts on base flow, water quality in receiving waters and erosion in watercourses. ![]()
