Here, you have to select the transport theory that will be used to calculate the rates of non-cohesive sediment transport in pure current or current and waves. In the second case, you have also to specify the wave data that will be used as input for the simulation.
You also have to specify the type and vales of Bed Resistance (p. 35) and the characteristics of the Sediment data (p. 35) that will be used in the simulation.
