The sampling location of each SEDFlume core also needs to be entered in Easting (m) and Northing (m) Coordinates for utilizing the Core Assignment features of EFDC_+ Explorer.


Figure 3  Erosion Rates Option 1 - Core Definitions Tab.

...

After completing the Core Definitions tab, the user may fill the Erosion Rate Matrix (cm/s) for Active & Deposited Sediment Bed in the Erosion Rates tab (Figure 4). This lookup table is used for calculating erosion rates in active & deposited bed layers as a function of their D50 size and an applied shear stress during the model simulation. The 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.  

Note: EFDC_+ Explorer provides a simple quality check for the erosion rate values entered by the user.  Specifically, cells will be highlighted if the erosion rate is not increasing as shear stress is increasing or the erosion rates is not decreasing as the D50 size is increasing. This is only a simple quality check within the user interface, so EFDC+ will still be able to run a model regardless of the quality of input erosion rates.
