Mr. Hill, Dynamic Solutions, LLC (www.dsllc.com) is the exclusive developer of the USEPA licensed EFDC Explorer pre and post processor. Originally developed in response to our internal needs to efficiently build and calibrate EFDC models, the advanced capabilities of the Explorer software were discovered and later licensed by USEPA Region 4 and the USEPA Environmental Laboratory in Athens, GA. EFDC Explorer is a Windows based, public domain GUI that allows rapid model setup, testing, calibration and quick visualization (and some animation) of model results. EFDC Explorer is the only software available that is built exclusively for use with the EFDC code, is Windows-based, user freindly,and that has robust capabilities for both pre and post processing. EFDC Explorer is currently being used by USEPA, USGS, USACE, Oklahoma Department of Environmental Protection, Texa Department of Environmental Quality, Suwannee River Water management District and other.
