Coupled Groundwater and Hydrodynamic Surface-Water Modeling of Southern Florida
Project Chief: Eric Swain
Figure 1 –Studies supporting numerical model development.
Hydrologic conditions in south Florida require special numerical tools to simulate the close surface-water/aquifer connection, the transient nature of the low-gradient flow, and transport of dissolved salt at the coast. Accurate hydrologic simulations are needed for determining coastal outflow rates, distribution and concentration of saline waters, the interaction between hydrology and ecology, and to predict the effects of restoration efforts and climate change on coastal hydrology. Development of the FTLOADDS simulator has been underway since 1996 to help meet those needs, and considerable data has been compiled as input to simulate the complex hydrology of the Everglades, the coastal Biscayne Bay area, and the Ten Thousand Islands area.
