Simulation of ground-water level fluctuations using recharge estimated by field infiltrometer measurements Simulation of ground-water level fluctuations using recharge estimated by field infiltrometer measurements
An infiltrometer was used at multiple locations at a site in Lee County, Fl. to define the spatial variability in infiltration parameters. Water-level data from a well at this site were collected hourly and used to determine the temporal variability in recharge. These results were used to define recharge in a representative stochastic numerical model of the aquifer. Model results without...

South Florida Ecosystem Program: Quantifying freshwater discharge for coastal hydraulic control structures in eastern Dade County, Florida South Florida Ecosystem Program: Quantifying freshwater discharge for coastal hydraulic control structures in eastern Dade County, Florida
The South Florida Ecosystem Restoration Program is an intergovernmental effort, involving a number of agencies, to reestablish and maintain the ecosystem of south Florida. One element of the restoration effort is the development of a firm scientific basis for resource decision making. The U.S. Geological Survey (USGS), one of the agencies, provides scientific information as part of the...

A coupled surface-water and ground-water flow model (MODBRANCH) for simulation of stream-aquifer interaction A coupled surface-water and ground-water flow model (MODBRANCH) for simulation of stream-aquifer interaction
Ground-water and surface-water flow models traditionally have been developed separately, with interaction between subsurface flow and streamflow either not simulated at all or accounted for by simple formulations. In areas with dynamic and hydraulically well-connected ground-water and surface-water systems, stream-aquifer interaction should be simulated using deterministic responses of...

Review and evaluation of a model for simulating the natural hydrology of South Florida Review and evaluation of a model for simulating the natural hydrology of South Florida
The South Florida Ecosystem Program is an intergovernmental effort to re-establish and maintain the ecosystem of South Florida. One element of the restoration effort is the development of a firm scientific basis for making management decisions. The U.S. Geologcal Survey (USGS) is one of the agencies that provides this needed scientific information through the USGS South Florida Ecosystem...

Description and field analysis of a coupled ground-water/surface-water flow model (MODFLOW/BRANCH) with modifications for structures and wetlands in southern Dade County, Florida Description and field analysis of a coupled ground-water/surface-water flow model (MODFLOW/BRANCH) with modifications for structures and wetlands in southern Dade County, Florida
A coupled surface-water model (BRANCH) and ground-water model (MODFLOW) model were tested to simulate the interacting wetlands/surface-water/ ground-water system of southern Dade County. Several options created for the MODFLOW ground- ground-water model were used in representing this field situation. The primary option is the MODBRANCH interfacing software, which allows leakage to be...

Spatial and temporal statistical analysis of a ground-water level network, Broward County, Florida Spatial and temporal statistical analysis of a ground-water level network, Broward County, Florida
The U.S. Geological Survey has developed a method to evaluate the spatial and temporal statistics of a continuous ground-water level recorder network in Broward County, Florida. Because the Broward County network is sparse for most spatial statistics, a technique has been developed to define polygons for each well that represent the area monitored by the well within specified criteria...
