EFDC has been enhanced with a range of heat exchange options providing you with increased flexibility and extra options when simulating complex thermal systems.
New Surface Heat Exchange Options
EFDC+ has two new surface heat exchange options, both of which allow for spatially and temporally varying surface heat exchange coefficients and light extinction factors. Beginning with 2008, the equilibrium temperature approach was added to EFDC, and with the release of 8.3, a new full heat exchange option has been added to EFDC+. The standard EFDC version only allows for heat exchange coefficients that are temporally and spatially constant, other than wind effects.
Heat Coupled Ice Modeling
EFDC+ implements a robust ice sub-model where ice formation and melt is simulated using the coupled heat model. This is a feature not available in other versions of EFDC or other environmental hydrodynamic modeling tools such as MIKE3 or DELFT3D.
Forced evaporation is defined as the additional evaporation due to increased temperatures in the receiving waters from the discharge of heated cooling water. Forced evaporation is being considered by federal and state agencies as a consumptive use for thermal electric power plants. EFDC+ provides the necessary toolbox to provide spatial and temporal evaluations of forced evaporation.
