abstract

  • As part of the Comprehensive Everglades Restoration Plan (CERP) initiated by the U.S. Army Corps of Engineers and the South Florida Water Management District, numerous structural improvements to the water management system of the Lower East Coast Service Areas of southern Florida have been proposed. As part of the conceptual design and evaluation process, a high-resolution ground water flow model of northern Miami-Dade County, Florida, was developed using MODFLOW96 along with a set of recently developed modules that allow the model to also simulate flow within wetlands, interactions between ground water and reservoirs, and the transfer of water throughout the model domain based on computed water levels. These modules include the Wetlands Package, a modified Lake Package the Reinjection Drain Flow Package, and the Operations Package. The primary objective for this model was to evaluate the effectiveness of the proposed system of improvements in achieving the goals identified by the CERP for the management of environmental and public water supplies. The specific model features that are of primary interest include proposed improvements such as subsurface reservoirs and surface impoundments used for the detention and treatment of surface water flows. Reservoir stages were computed using the Lake package while seepage from and stages within surficial impoundments were successfully simulated using the Wetlands package. In the latter case, the option to include user-specified water diversions was used to account for certain pumped inflows and outflows required for regional water supply purposes. At selected impoundments, the Reinjection Drain Flow package was applied to simulate the backpumping of seepage that was intercepted by perimeter borrow canals. Finally, other water transfers between surficial impoundments, reservoirs and ASR wells that are a function of reservoir stage were incorporated into the model using the Operations package. © 2001 American Society of Civil Engineers.
