Abstract: Weeks Bay system models describing water elevation, water circulation, salinity and BOD/DO concentrations are used to investigate two case study scenarios - a dredged ten foot deep boat channel and an accidental discharge of BOD laden water in one of the rivers. Each analysis shows the impact that such activities have on the bay by comparing pre- and post-condition values of system parameters determined from the models. In the case of the dredged channel, the salinity values at four locations are compared. A BOD/DO concentration profile is used within the Fish and Magnolia Rivers (as a function of river distance) to show the effect of the entering fresh water conditions on the Weeks Bay system.
