Abstract
Aspects of a detention pond retrofit device for detention basin outlet control provide structures designed to throttle stormwater flow and maintain the rate at which water is discharged from the system below Qcritical, the flow rate at which erosion and down cutting of the receiving stream would begin, based on channel morphology and bed material resistance. The primary goal of the device is to induce increased flow detention during low to moderate rain events, while providing similar hydraulic performance during large events to that of the detention basin performance prior to the installation of the retrofit unit. This is achieved through a 'T' or 'Y' design with split flow paths, in which the lower path is hydraulically restricted through the installation of structures while the upper path is unrestricted.
