ANALYTICAL SOLUTION FOR DENSITY CURRENTS IN SETTLING BASINS

An analytical model is presented, which is capable of predicting sediment-induced density currents and sediment-concentration disributions in settling basins with negligible flow through. The paper compares analytical results with available experimental data. The solution procedure integrates the governing equations over the depth. It assumes that the vertical profiles for velocity and concentrations are self-similar. The analytical solution indicates that the layer velocity decreases linearly along the length of the channel for both laminar and turbulent flows. Heuristic profiles are estimated for both flow regimes and the magnitudes of both the interfacial friction factor and the bottom friction factor.
