Documentation of a Conduit Flow Process (CFP) for MODFLOW-2005 Documentation of a Conduit Flow Process (CFP) for MODFLOW-2005
This report documents the Conduit Flow Process (CFP) for the modular finite-difference ground-water flow model, MODFLOW-2005. The CFP has the ability to simulate turbulent ground-water flow conditions by: (1) coupling the traditional ground-water flow equation with formulations for a discrete network of cylindrical pipes (Mode 1), (2) inserting a high-conductivity flow layer that can...

Numerical modelling to determine freshwater/saltwater interface configuration in a low-gradient coastal wetland aquifer Numerical modelling to determine freshwater/saltwater interface configuration in a low-gradient coastal wetland aquifer
A coupled hydrodynamic surface-water/groundwater model with salinity transport is used to examine the aquifer salinity interface in the coastal wetlands of Everglades National Park in Florida, USA. The hydrology differs from many other coastal areas in that inland water levels are often higher than land surface, the flow gradients are small, and, along parts of the coastline, the wetland...

A model for simulation of surface-water integrated flow and transport in two dimensions: user's guide for application to coastal wetlands A model for simulation of surface-water integrated flow and transport in two dimensions: user's guide for application to coastal wetlands
The computation of hydrodynamic flow in two dimensions is implemented in the Surface-Water Integrated Flow and Transport in Two-Dimensions (SWIFT2D) model using a numerical code that also includes computation of reactive constituent transport, density variation effects, drying and wetting of periodically inundated areas, and hydraulic structures. The model can be utilized in a variety of...

Simulation of integrated surface-water/ground-water flow and salinity for a coastal wetland and adjacent estuary Simulation of integrated surface-water/ground-water flow and salinity for a coastal wetland and adjacent estuary
The SWIFT2D surface-water flow and transport code, which solves the St Venant equations in two dimensions, was coupled with the SEAWAT variable-density ground-water code to represent hydrologic processes in coastal wetlands and adjacent estuaries. A sequentially coupled time-lagged approach was implemented, based on a variable-density form of Darcy's Law, to couple the surface and...

Two-dimensional hydrodynamic simulation of surface-water flow and transport to Florida Bay through the Southern Inland and Coastal Systems (SICS) Two-dimensional hydrodynamic simulation of surface-water flow and transport to Florida Bay through the Southern Inland and Coastal Systems (SICS)
Successful restoration of the southern Florida ecosystem requires extensive knowledge of the physical characteristics and hydrologic processes controlling water flow and transport of constituents through extremely low-gradient freshwater marshes, shallow mangrove-fringed coastal creeks and tidal embayments, and near-shore marine waters. A sound, physically based numerical model can...

Assigning boundary conditions to the Southern Inland and Coastal Systems (SICS) model using results from the South Florida Water Management Model (SFWMM) Assigning boundary conditions to the Southern Inland and Coastal Systems (SICS) model using results from the South Florida Water Management Model (SFWMM)
The Comprehensive Everglades Restoration Plan (CERP) requires the testing and evaluation of different water-management scenarios for southern Florida. As part of CERP, the South Florida Water Management District is using its regional hydrologic model, the South Florida Water Management Model (SFWMM), to evaluate different hydrologic scenarios. The SFWMM was designed specifically for the...

An analytical formulation of two‐dimensional groundwater dispersion induced by surficial recharge variability An analytical formulation of two‐dimensional groundwater dispersion induced by surficial recharge variability
A predominant cause of dispersion in groundwater is advective mixing due to variability in seepage rates. Hydraulic conductivity variations have been extensively researched as a cause of this seepage variability. In this paper the effect of variations in surface recharge to a shallow surficial aquifer is investigated as an important additional effect. An analytical formulation has been...

Determining discharge-coefficient ratings for selected coastal control structures in Broward and Palm Beach counties, Florida Determining discharge-coefficient ratings for selected coastal control structures in Broward and Palm Beach counties, Florida
Discharges through 10 selected coastal control structures in Broward and Palm Beach Counties, Florida, are presently computed using the theoretical discharge-coefficient ratings developed from scale modeling, theoretical discharge coefficients, and some field calibrations whose accuracies for specific sites are unknown. To achieve more accurate discharge-coefficient ratings for the...

Review of selected features of the natural system model, and suggestions for applications in South Florida Review of selected features of the natural system model, and suggestions for applications in South Florida
A study was conducted to review selected features of the Natural System Model, version 4.3 . The Natural System Model is a regional-scale model that uses recent climatic data and estimates of historic vegetation and topography to simulate pre-canal-drainage hydrologic response in south Florida. Equations used to represent the hydrologic system and the numerical solution of these...
