This option has the same erosion rates calculation approach as Erosion Rates Option 2 and the same bed properties definition approach as original sediment transport model (see In the General tab, the user selects the last bottom option as shown in Figure 1. This option, erosion rate will base on equation E = A*Tau^N with A (Erosion Multiplier), N (Erosion Exponent) elements and Bed Properties Using. A and N will be defined in Erosion Rates tab as shown in Figure 3.
When the erosion rate option 3 is selected, the Assign Bed IC button is enable, click on the button, a form of Initialization of Sediment Beds appears as shown in Figure 2. The user can refer to Sediment Bed Construction section for more details).
