Sediment transport open boundary conditions

Three different open inflow boundary conditions are available.

Sediment transport

Sediment inflow is specified for each sediment component. If relevant, the inflow is divided into bed load and suspended load by the engine such that the total inflow is equal to the specified inflow.

Bottom level

One can choose either to specify the bottom level at relevant boundaries or specify the bottom level change. Both can be given as constants or time series.

Sediment supply

Sediment supply assumes the inflow to match the sediment load capacity in the first grid point. It has the same effect as setting bottom level change of zero.
