Application of the South Florida Regional Simulation Model in the Southern Everglades
The South Florida Regional Simulation Model (SFRSM) is used in this study to simulate flow-dynamics in the Everglades National Park (ENP). The SFRSM, a model under development by the South Florida Water Management District (SFWMD), was designed to simulate major components of the hydrologic cycle as well as the complex water management rules and policies in South Florida. This paper focuses only on the physical processes such as overland and ground water flow, evapotranspiration, levee seepage, and canal flow that dominate the hydrology within the study area. The current working version of the SFRSM, referred to as the Hydrologic Simulation Engine (HSE) is a weighted, implicit, finite-volume, rainfall-runoff model, capable of simulating two-dimensional flow using a variable mesh with arbitrarily shaped triangular elements. One-dimensional canal flow and two-dimensional overland flow are simulated in the model using the diffusive wave approximation of the Saint Venant equation. The Darcy equation is used for the one-dimensional canal seepage and two-dimensional groundwater flow calculations. Overland and groundwater flow components are fully coupled for a more realistic representation of runoff generation. This feature makes the HSE ideally suited for simulating high water tables and relatively flat terrains associated with the Everglades. Calibration results show that the HSE provides stage history-matching capabilities comparable to the South Florida Water Management Model — the more thoroughly-tested regional simulation model for the same region.
