Historically, natural drainage of the vast Everglades watershed resulted in seasonal fluctuations in the salinity of near-shore waters. Though over a century of water management has dramatically altered these patterns, it is anticipated that restoration efforts will return seasonal flows to our coastal waters, bringing about renewed vitality and health. To that end, project planners depend upon predictive modeling to help simulate the effects of proposed improvements.

Building upon earlier CESI-funded investigations, this project identifies important links between hydrology and salinity that can help develop a series of predictive multivariate linear models. These models can be used to help describe the temporal and spatial variation that can be expected from restoration activities. Investigators produced models for drainage basins in Florida Bay, Barnes Sound / Manatee Bay, and portions of Shark Slough.
