In the General tab, under Erosion Rate Options the user selects should select the last bottom second option as shown in Figure 1. This Using this option , the erosion rate will base be based on the equation E = A*Tau^N with A (Erosion Multiplier), N (Erosion Exponent) elements and Bed Properties By Core ID. A and N where "A "is the erosion multiplier, and "" is erosion exponent, and it uses bed properties by Core ID. "A" and "N" will be defined in the Erosion Rates tab as shown in Figure 2. Moreover, with this option, the user can define the maximum erosion rate of each grain size.

Next, under the user goes to Core Definitions tab, the user fills to the grid frame of should enter the values for the Bed Layer Properties and Grain Size Distribution as table as described in Erosion Rates Option 1, for the grid frame of SEDFlume Measured Erosion Rates, the  . The user needs to define "A", "N", and the maximum erosion rates of each sediment bed layer as shown in Figure 3.
