Design of Forebay and Micropool for Highway Stormwater Detention Basins

Low Impact Design, an innovative and green method for stormwater design, often begins with a learning process and needs to be tested with field data. This study will investigate the performance and design assumptions of two popular stormwater detention basin designs: water quality capture volume (WQCV) and excess urban runoff volume (EURV). WQCV ponds are built to intercept up to 6-month rainfall events for water quality control, while EURV ponds are designed for all flow release controls from small to extreme events. Refining forebay and micropool designs to avoid or minimize standing pools is a major goal of the detention basin study.
