hyperpycnal flow At a river mouth, a flow of river water that is denser than the water in the basin receiving it. This occurs during floods. The denser water flows beneath the basin water, as a density current, carrying sediment beyond the shore and inhibiting the progradation of a delta. Compare HOMOPYCNAL FLOW; and HYPOPYCNAL FLOW.
