Modeling Grand Bay Marsh Productivity with Sea-Level Rise

Detailed Description

Scientists at the USGS St. Petersburg Coastal and Marine Science Center use Hydro-MEM, a two-dimensional coastal wetland model that integrates an Advanced Circulation hydrodynamic model with a Marsh Equilibrium Model to project marsh response to sea-level rise. In Grand Bay, the model predicts that marshes will lose productivity under a high sea-level rise scenario, and attempt to migrate upland or convert to open water.

The graphic (Alizad and others, 2018) shows predicted model output of marsh productivity in Grand Bay under a high sea-level rise scenario between the year 2000 and 2100.
