After completing the Core Definitions tab, the user may fill the Active and Deposited Sediments Erosion Matrix in the Erosion Rates tab (Figure 4). This lookup table is used for calculating erosion rates in active & deposition bed layers as a function of their D50 size and an applied shear stress during the model simulation. The use user may see that the first row of this matrix present the shear stress classes (dynes/cm2) as the same as the classes specified in the Core Definitions tab (This is the reason why the user needed to complete the Core Definitions tab first). To fill this lookup table, the user may utilize the SEDFlume core test results or can adjust them manually for model calibration.
