SEAWAT model used to evaluate the potential effects of alterations to the hydrologic system on the distribution of salinity in the Biscayne aquifer in Broward County, Florida.

Joseph D. Hughes, Dorothy F. Sifuentes & Jeremy T. White
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...

North Sea Interactive

The North Sea Interactive (NSI) project was an 8-month NERC funded project led by Heriot-Watt University, in collaboration with the BGS and NOC. The aim of the project was to develop a new decision-support tool that would translate existing marine environmental data into an interactive mapping product for the offshore oil and gas industry.

SE4CF Models Based on Limited Data

Jennifer Nichols, Wendy Murray & Michael Bednar
Kinematic models of scaphoid-excision four-corner fusion (SE4CF) developed in SIMM v. 6.0.2. These models are based on several assumptions and limited experimental data.

MODFLOW-2005 and MODPATH6 models used to delineate areas contributing groundwater to selected surface receiving waters for long-term average hydrologic stress conditions from 1968 to 1983, Long Island, New York

Paul E. Misut
A regional groundwater-flow model and particle-tracking program were used to delineate areas contributing groundwater to coastal and freshwater bodies and to estimate travel times from the water table to saline water bodies under average conditions from 1968 to 1983 on Long Island, New York. The coastal waters of Long Island are important economic and recreational resources for the region. The coastal water bodies receive freshwater from inflow of both surface water and groundwater, in addition...

MODFLOW2005 model used to simulate the effects of groundwater withdrawals from aquifers in Ocean County and vicinity, New Jersey

Stephen J Cauller, Lois M Voronin & Mary M Chepiga
A three-dimensional groundwater flow model was developed to simulate the effects of withdrawals on the groundwater-flow systems of five aquifers in and around Ocean County, New Jersey-the unconfined Kirkwood-Cohansey aquifer system and Vincentown aquifer, and three confined aquifers--the Rio Grande water-bearing zone, the Atlantic City 800-foot sand, and the Piney Point aquifer. A transient model was used to simulate conditions that represent no groundwater withdrawals, 2000-2003 groundwater withdrawals, and maximum-allocation groundwater withdrawals. Particle-tracking analysis, using...

Stochastic Empirical Loading and Dilution Model (SELDM) Software Support Web Page

Gregory E Granato
The Stochastic Empirical Loading and Dilution Model (SELDM) is designed to transform complex scientific data into meaningful information about the risk of adverse effects of runoff on receiving waters, the potential need for mitigation measures, and the potential effectiveness of such management measures for reducing these risks. The U.S. Geological Survey developed SELDM in cooperation with the Federal Highway Administration to help develop planning-level estimates of event mean concentrations, flows, and loads in stormwater from...

Near-surface wind fields for San Francisco Bay--historical and 21st-century projected time series

Andrea O'Neill, Li H. Erikson & Patrick Barnard
To support Coastal Storm Modeling System (CoSMoS) in the San Francisco Bay (v2.1), time series of historical and 21st-century near-surface wind fields (eastward and northward wind arrays) were simulated throughout the Bay. While global climate models (GCMs) provide useful projections of near-surface wind vectors into the 21st century, resolution is not sufficient enough for use in regional wave modeling projects, such as CoSMoS. Short-duration high wind speeds, on the order of hours, are of key...

GSFLOW model simulations used to evaluate the impact of irrigated agriculture on surface water groundwater interaction

Hedeff I. Essaid, Rodney Caldwell & Jim Constantz
Watershed-scale coupled surface water (SW) groundwater (GW) flow modeling was used to examine changes in streamflow and SW GW interaction resulting from irrigation and associated SW diversions and GW pumping. The U.S. Geological Survey (USGS) model GSFLOW, an integration of the USGS Precipitation-Runoff Modeling System (PRMS) and the Modular Ground-Water Flow Model (MODFLOW), was utilized for this effort. Processes represented in the model include daily rain, snowfall, snowmelt, streamflow, surface runoff, interflow, infiltration, soil-zone evapotranspiration...

MODFLOW2000_FMP1_1 model used to simulate the groundwater flow of the Central Valley Aquifer, California

Claudia C. Faunt
A three-dimensional groundwater flow model (MODFLOW200-FMP1_1) of the Central Valley in California was developed to aid water managers in understanding how water moves through the aquifer system, to predict water-supply scenarios, and to address issues related to water competition. The USGS Groundwater Resources Program made a detailed assessment of groundwater availability of the Central Valley aquifer system, which includes: (1) the present status of groundwater resources; (2) how these resources have changed over time; and...

MODFLOW2000 model used to simulate the groundwater flow of the Denver Basin Aquifer System, Colorado

Edward R. Banta, Suzanne S. Paschke & David W. Litke
A three-dimensional groundwater flow model (MODFLOW2000) of the Denver Basin bedrock aquifer system and overlying alluvial aquifer was developed to provide quantitative estimates of groundwater flow conditions and provide a useful tool for managers to analyze temporal changes to the hydrologic system in response to changing climatic conditions and future groundwater development. In 2004, the U.S. Geological Survey (USGS) initiated large-scale regional studies to provide updated assessments of groundwater availability in important principal aquifers across...

MODFLOW-NWT 2016 groundwater flow model for Dane County, Wisconsin

Kenneth R. Bradbury Michael J. Parsen
A new groundwater flow model was created for Dane County, Wisconsin, to replace an earlier model developed in the 1990s by the Wisconsin Geological and Natural History Survey (WGNHS) and the U.S. Geological Survey (USGS). This modeling study was conducted cooperatively by the WGNHS, the Capital Area Regional Planning Commission, and the USGS. Although the overall conceptual model of the groundwater system remains largely unchanged, the incorporation of newly acquired, high-quality datasets, recent research findings,...

SUTRA model used to evaluate the role of uplift and erosion in the persistence of saline groundwater in the shallow subsurface

Richard M. Yager, Clifford I Voss & Ward E. Sandford
A modified version of the three-dimensional, variable-density solute-transport model (SUTRA) was developed to simulate the effects of erosion and uplift on the flushing of brine with meteoric water in Permian through Mississippian rocks of the Appalachian Plateaus. The model was run in 10-Ma transient simulations for a range of values of permeability and anisotropy. Model results indicate that the depth of shallow Paleozoic brine in the Appalachian Plateaus is controlled by the flushing rate of...
