Water Quality Interface

EFDC_Explorer (EE FULL) provides a full featured user interface to the HEM3D water quality features including setting initial conditions, boundary conditions, default kinetic parameters, and sediment diagenesis. Robust post processing tools of the water quality results including 2D plan (by layer or depth averaged) and vertical section plots and animations, submerged aquatic vegetation (SAV) analysis, light penetration analysis, habitat analysis, etc. are available.

EFDC Explorer (FULL Version) may be purchased by registered users of this website. Note that EFDC_Explorer (WEB Version) has the water quality interface disabled.

The Algae/WQ Initial Conditions tab allows the user to set various Algae Options, and the Initial Conditions, whether spatially constant or spatially varying.

6

The Water Quality Boundary Conditions tab allows the user to decide whether to apply time variable Point Source MASS Loading or time variable Point Source Concentrations.
