The objective of this investigation was to present an algorithm that would model the movement of sediment in detention ponds. The cornerstone of the algorithm is the coupling of reactor theory concepts with advection-diffusion processes. Reactor theory concepts are used to (1) determine residence times of sediment particles and (2) to calculate mixing in the horizontal plane. Advection-diffusion processes are used to model the settling characteristics and turbulent diffusion of sediment. Also incorporated in the model is a bed scour routine based on the statistical properties of turbulent lift forces. Empirical coefficients for the bed scour routine are evaluated by using previously published results.
