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 Southern Everglades Coastal Transport (BISECT) Model
Description
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. BISECT was constructed by combining two existing
models, Tides and Inflows to the Mangrove Everglades (TIME)
(https://doi.org/10.3133/sir20075010), and Biscayne
(https://doi.org/10.3133/sir20125099), and modifying the Flow and
Transport in a Linked Overland/Aquifer Density-Dependent System
(FTLOADDS) simulator (https://doi.org/10.1016/j.jhydrol.2005.04.015)
to include spatially variations in the solar radiation reflected back into
the atmosphere from the Earth’s surface (albedo) to improve model
results. Input data files, containing parameters and boundary condtions
for groundwater and surface-water, were developed for the calibrated
model, representing 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 for the 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.org/10.3133/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.
