In order to activate or deactivate modules, the user should RMC on Modules menu item. The EFDC Modules form will be displayed as shown in Figure 1.
The Active Modules frame provides access to the computational and transport switches and options that are contained in C6 in EFDC.INP. These switches are the primary activation switches to specify which state variable(s) will be simulated by EFDC. Figure 1displays the maximum number of modules currently allowed in the EFDC_Explorer/EFDC+ modeling system. Selecting a check box will display a new module as a sub-tab in Modules, and deselecting a box will hide it.
If the Activate Cohesive Sediments or the Activate Non-Cohesive Sediment boxes have been selected, the user may make changes to the sediments and sediment bed settings.
The user should first define the sediment model intended by selecting the appropriate option in the check box. Two sediment models are available by choosing either Original Model or SEDZLJ Model. The SEDZLJ Sediment sub-model is fully implemented in EFDC_Explorer. EFDC_Explorer can display SEDZLJ results including sediment fluxes and active layer thicknesses.
