Flocculation and Transport of Cohesive Sediments Collected from a Stormwater Detention Pond

Abstract
A new model for modeling suspended sediment from an on-stream stormwater management pond is presented. It is based on Krishnappans' model of flocculated settling in still water, which was extended to dynamic conditions and verified by experiments with stormwater pond sediment in a laboratory rotating flume. The model was derived from first principles, but some input parameters, such as floc properties, had to be obtained by calibration, and input parameters describing flow field properties were obtained from a k - ε turbulence model. Simulated suspended concentrations vs. time, produced with the calibrated model, agreed well with flume measurements.
