FTLOADDS (combined SWIFT2D surface-water model and SEAWAT groundwater model) simulator used to assess proposed sea-level rise response and water-resource management plans for the hydrologic system of the South Florida Peninsula for the Biscayne and Southe

The Biscayne and Southern Everglades Coastal Transport(BISECT) model combines a three-dimensional groundwater model with a two-dimensional hydrodynamic surface-water model with variable-density solute-transport. Input data files containing parameters and boundary condtions for groundwater and surface-water were developed for the calibrated model, represnting conditions from 1996 to 2004. Input data scenarios were developed by altering the relevent parameters to represent the likely effects of 1) different depth aquifer barriers, 2) possible future changes to current water-management practices, and 3) two values of sea-level rise. Output files indicate the effects of these input on surface-water stages and flows, hydroperiod, and groundwater levels and salinity. Additional input and output files he model was tested for sensitivity by perturbing the parameters for frictional resistance, wind forcing, tidal amplitude, thickness of surfical transistion layer, conductance of canal beds, vertical and horizontal aquifer conductance, and albedo. This USGS data release contains all of the input and output files for the simulations described in the associated model documentation report (https://doi:10.5066/SIR20195045). This data release also includes (1) postprocessing Fortran scripts and associated input data files for the sensitivity and scenarios runs, (2) the FTLOADDS source code.
