Storm Water Best Management Practice: Development of Debris Filtering Structure for Supercritical Flow
A simple, but effective, debris removal structure was developed for supercritical flow in urban storm water channels. This structure was designed as a best management practice in response to the National Pollution Discharge Elimination System. The Drop Flow Debris Filter (DFDF) structure consists of two slightly sloped plates, one placed above the other to form a debris basin. The DFDF structure translates supercritical flow of the storm water channel into subcritical flow in the debris basin. This system creates flow paths that only allow water in the bottom of the basin to pass through while debris is retained in the upper part of the basin. To investigate the hydraulic performance of the DFDF structure, a 1:3 scale undistorted physical model was constructed in a 0.91 m wide plexiglass flume. This model was also created in a three-dimensional computational fluid dynamics program. Three different density spheres were used in this model study to reproduce different buoyant storm water debris. Six different DFDF designs were developed and tested, and the modified curved plates design was recommended for the best performing DFDF structure.
