Modeling Information

The modeling information presented below has been reorganized in an attempt to provide more clarity. Current modeling information is differentiated from historical information. The intent is to retain the historical information for those interested, but make it easier to locate the latest information. The project is employing the EFDC model for salinity information; the WASP model for water quality information and two Marsh Succession Model suites of modules for marsh succession prediction. (For this, the EFDC model provides the input data which is processed by the Marsh Succession Model suite.)

General Information
The salinity and water quality model development history leading up to the EFDC and WASP model development is located here. It is an attempt to provide a chronological description of the many events, meetings, decisions, and reports developed during those years of effort. This chronology ends with the beginning of the adaptation of the EFDC and WASP models for use as detailed below.
