A table summarizing the inventoried acreage by crop type and irrigation system was compiled for Lake County, Florida. The irrigated acreage totals were derived from analyses of satellite and aerial imagery. Crop types and irrigation system types were verified during field trips that started in January 2020 and concluded in December 2020. In addition, the table provides acreage totals by crop type reported by the U.S. Department of Commerce for 1982, the U.S. Department of Agriculture from 1987 through 2017, and Florida Statewide Agricultural Irrigation Demand for 2016-18.

A three-dimensional, variable-density solute-transport model (SEAWAT) was developed to examine causes of saltwater intrusion and predict the effects of future alterations to the hydrologic system on salinity distribution in eastern Broward County, Florida. The model was calibrated to conditions from 1970 to 2012, the period for which data are most complete and reliable, and was used to simulate historical conditions from 1950 to 2012. The model was used to (1) evaluate the sensitivity of the salinity distribution in groundwater to sea-level rise and groundwater pumping , and (2) simulate the potential effects of increases in pumping, variable rates of sea-level rise, movement of a salinity control structure, and...
The Biscayne and Southern Everglades Coastal Transport(BISECT) model combines a three-dimensional groundwater model with a two- dimensional hydrodynamic surface-water model with variable-density solute-transport. BISECT was constructed by combining two existing models, Tides and Inflows to the Mangrove Everglades (TIME) (https://doi.org/10.3133/sir20075010), and Biscayne (https://doi.org/10.3133/sir20125099), and modifying the Flow and Transport in a Linked Overland/Aquifer Density-Dependent System (FTLOADDS) simulator (https://doi.org/10.1016/j.jhydrol.2005.04.015) to include spatially variations in the solar radiation reflected back into the atmosphere from the Earth’s surface (albedo) to improve model results....
To accurately estimate agricultural water use or to project future water demands, a detailed inventory of current irrigated crop acreage is needed at a high level of resolution. In many Florida counties this kind of detailed high-resolution inventory is not available. A detailed digital map and summary of irrigated acreage during the 2015 growing season was developed for 13 of the 15 counties that compose the Suwannee River Water Management District. The irrigated areas were delineated using land-use data, orthoimagery, water management district consumptive water-use permits, and digitized agricultural landuse maps developed by the Florida Department of Agriculture and Consumer Services, Florida Statewide Agricultural...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. The Springs data set was initially created using the Florida Department of Environmental Protection (FDEP), but was further enhanced by adding the Georgia and Alabama springs using the USGS NWIS and GNIS databases.
The U.S. Geological Survey, in cooperation with the Southwest Florida Water Management District, calibrated a model to quantify the inflows and outflows in the Floral City, Inverness, and Hernando pools of the Tsala Apopka Lake basin in Citrus County, Florida. The calibrated model, which uses MODFLOW-NWT version 1.1.2, simulates hydrologic changes in pool stages, groundwater levels, spring flows, and streamflows caused by the diversion of streamflow from the Withlacoochee River to the Tsala Apopka Lake basin through water-control structures. A surface-water/groundwater flow model was developed using hydraulic parameters for lakes, streams, the unsaturated zone, and the underlying surficial and Upper Floridan aquifers...
Groundwater withdrawals are published by county and use type every 5 years by the U.S. Geological Survey (http://water.usgs.gov/watuse/) and published values often do not specify the aquifer(s) from which the withdrawals are derived. The items included in this dataset represent estimates of water use by aquifer in the southeastern United States in order to provide better insight into the 3-dimensional distribution of groundwater withdrawals in time and space.

These files were compiled through a cooperative project between the U.S. Geological Survey and the Florida Department of Agriculture and Consumer Services, Office of Agricultural Water Policy. Information provided in the shapefile includes the location of irrigated lands that were verified during field surveying that started in May 2021 and concluded in August 2021. Field data...
A detailed table summarizing the irrigated acreage by crop type and irrigation system was developed for the 2018 growing season (November 2017 and September 2018) for Hillsborough County, Florida. The acreage totals presented are derived from the results of a cooperative project that mapped and field-verified irrigated fields in Hillsborough County, Florida. In addition, the table provides acreage totals by crop type published by the U.S. Department of Commerce for 1978 and 1982 and the U.S. Department of Agriculture for years between 1987 and 2012.

The U.S. Geological Survey (USGS), in cooperation with the U.S Fish and Wildlife Service, has investigated the hydrology of the Great Dismal Swamp (Swamp) National Wildlife Refuge (Refuge) in Virginia and North Carolina and developed a three-dimensional numerical model to simulate groundwater and surface-water hydrology. The model was developed with MODFLOW-NWT, a USGS numerical groundwater flow modeling program, in combination with the Surface-Water Routing Process, a software package that simulates dynamic surface-water flows, water-control-structure management, and groundwater/surface-water interactions. The steady-state model was calibrated to average spring conditions using automated parameter estimation software...
This model is a preliminary characterization of trichloroethene transport in the surficial and Cambrian-Ordovician aquifer systems at the Naval Industrial Reserve Ordnance Plant in Fridley, Minnesota. The characterization first considered 2001 conditions using a MODFLOW and MT3DMS, followed by an application of this 2001 model to 2011 conditions. The U.S. Geological Survey (USGS), in cooperation with the U.S. Department of the Navy, used the steady-state, uniform-density groundwater flow model MODFLOW to calculate potentiometric heads in aquifer systems on August 20, 2001; and the single-phase, conservative, non-reactive, miscible transport model MT3DMS to calculate trichloroethene concentrations in aquifer systems...
The previously developed Biscayne and Southern Everglades Coastal Transport (BISECT) model, which combines a three-dimensional groundwater model with a two-dimensional hydrodynamic surface-water model with variable-density solute-transport (https://doi.org/10.3133/sir20195045), was used to evaluate the hydrologic response to historical and hypothesized modern hurricane strikes. Simulations were implemented using FTLOADDS (Flow and Transport in a Linked Overland/Aquifer Density-Dependent System) which is a coupled hydrodynamic surface-water and groundwater simulator that was developed by the U. S. Geological Survey to improve understanding of the complex and interconnected hydrology in South Florida. A simulation...
