The fully coupled nature of the EFDC+ model has the great advantage of not requiring external linkage to other sub-models or executable files, therefore simplifying complex simulations. All calculations are undertaken internally in the EFDC+ code, which contains all the sub-models, such as hydrodynamics, wind generated waves, temperature, salinity, dye, sediment transport, toxics, water quality and more. To facilitate the management of this wide range of options EE allows each module to be turned on and off in one location as shown below. Only when the user turns on a given sub-model are the respective options displayed. This assists you in building a model in a logical, step-by-step process, and keeps the GUI orderly and concise.
EE saves the user considerable time by automatically initializing EFDC+ parameters and settings with commonly used default parameters. For example, if the user turns on the Water Quality sub-model, hundreds of water quality parameters are initialized. The user can then modify these as required by the needs of their study.
The option to load default parameters from existing models is also provided.
