Summary
Basins are areas for storage of surface runoff that are free from water under dry weather flow conditions. Basins are bodies of water designed to store surface runoff. They play a critical role in stormwater management by reducing flood risk and improving water quality. The performance of basins is highly site-dependent and often requires upstream source control to function effectively. There are three main types of basins: retention,...
