The second tab on the Sediment Data Editor defines sediment boundary conditions (see figure below). Like the unsteady and quasi-unsteady flow boundary conditions, HEC-RAS requires sediment data at each upstream model boundary and can include optional, local, lateral sediment loads where necessary. The editor automatically lists external model boundaries and users can add local sediment loads at internal cross sections by pressing the Add Sediment Boundary Location(s) button.
