The WQ - Kinetics tab is shown in Figure 1. Some of the user options include setting the Global Kinetic Options from one of several modules. For the EFDC_GVC version, the standard kinetic model is contained in Module 3 (ISWQLVL=3). While the other kinetic modules may be used (with care) when using the EFDC_GVC version in the standard sigma mode, if the GVC option is selected ONLY module 3 works. For the EFDC_DSI + version, the standard full kinetic module is Module 1 (ISWQLVL=1). Once the kinetic option has been chosen the user still needs to select which parameters will be varied/simulated within the selected kinetic option. Clicking the Params button brings up the list of parameters whose simulation (i.e. advection and dispersion) can be switched on or off. However, even if a parameter is not simulated, since it is still part of the kinetics, the IC concentration is used for all of the kinetic calculations.

EE will automatically initialize the the water quality sub-model using the Access template file (EFDC.MDB). However, it is often convenient to initialize a new model using data from another EFDC_Explorer model with similar conditions. This is done using the "Initialize Initialize WQ Parameters from File in the Miscellaneous frame. This operation should only be conducted once at the start of the water quality model construction. This process overwrites all of the current model's settings.
