This should be in general correct that sediment redistribution within a system should be sthg else then inflow of sediments into the system (e.g. in oceans, on shelfs). Of course, for redistribution of (deposited) sediments remobilizaion (entrainment), transport by currents/flows and (new) deposition is needed.
But we need a definition about sediment redistribution. Can we say that sediment redistribution is a process included sediment or soil remobilization, transport and deposition in the base of sediment storage?
