Which phenomenon causes density currents to transport sediment along lake bottoms after a flash flood?

💡 Explanation

When suspended sediment concentrations increase during rapid inflow, turbidity flows are generated because the density of the water increases beyond that of the ambient lake water, causing downslope movement. Therefore a density current results, rather than settling, rebound, or capillarity which involve different physical mechanisms.
