This is the Read Me file for EFDC – EPA Version 1.01. The Environmental Fluid Dynamics Code (EFDC) is a multifunctional surface water modeling system, which includes hydrodynamic, sediment-contaminant, and eutrophication components. The public domain EFDC model was developed by Dr. John M. Hamrick at the Virginia Institute of Marine Science and is currently maintained by Tetra Tech, Inc. with support from the U.S. EPA. EFDC has been used for more than 80 modeling studies of rivers, lakes, estuaries, coastal regions and wetlands in the United States and abroad.
