Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs

June 21, 2022

Using the Hydrodynamic-Marsh Equilibrium Model (Hydro-MEM), the wetlands system within the Apalachicola-Big-Bend region of Florida (FL) (Fig. 1) was assessed using three sea-level rise scenarios of intermediate-low (50 centimeters [cm] by 2100), intermediate (1 meter [m] by 2100), and intermediate-high (1.5 m by 2100) from the National Oceanic and Atmospheric Administration (NOAA). Hydro-MEM input data includes elevation, tidal forcings, river inflow, and field-collected parameters and couples a hydrodynamic and biological model to capture feedback processes in the wetland system. The model incorporated a spatially-varying marsh parabola parametrization and considered sea-level rise induced salinity intrusion proxy in the system. This data release includes initial conditions and future conditions under three SLR scenarios and model outputs of marsh vegetation type and productivity, which is based on biomass density. For further information regarding model input generation and visualization of model output, refer to the metadata of this data release.
