A mathematical model of turbulent density‐driven flows is presented and is solved numerically. A form of the k –ϵ turbulence model is used to characterize the turbulent transport, and both this non‐linear model and a sediment transport equation are coupled with the mean‐flow fluid motion equations. A partitioned, Newton–Raphson‐based solution scheme is used to effect a solution. The model is applied to the study of flow through a circular secondary sedimentation basin.
