ABSTRACT
ABSTRACT: The key role of detention and retention basins in stormwater management, sedimentation/pollution control, and environmental protection, is evaluated through best management practice design recommendations. An overview of the engineering approach to stormwater routing and analysis of basins’ sediment trapping efficiency is given. Design topics such as: stormwater treatment efficiency, control structures, release impacts, vegetation and landscape, maintenance, legal and social implications of basin construction, are discussed. Finally, two illustrative case studies are presented – one pertaining to urban stormwater management by a system of detention basins, and the other, pertaining to a retention basin with the primary role to provide environmental, ambient stream corridor preservation.
