A three-dimensional groundwater flow model (MODFLOW-NWT) of the Columbia Plateau Regional aquifer (CPRAS) in Washington, Oregon, and Idaho was developed to provide an integrated understanding of the hydrologic system to implement effective water-resource management strategies. The U.S. Geological Survey (USGS) Groundwater Resources Program assessed the groundwater availability as part of a national study of regional systems (https://pubs.usgs.gov/circ/1323/). The CPRAS assessment includes the status of groundwater resources, how these resources have changed over time, and development and application of tools to estimate system responses to stresses from future uses and climate variability and change. A major product...
A digital model of the sedimentary Northern Atlantic Coastal Plain aquifer system is composed of 20 rasters and hydrogeologic unit extent polygons. Rasters describe the top elevations of regional aquifers and confining units at a resolution of 2640 feet (1/2 mile). The rasters are clipped to the extent polygons, which represent the spatial extents of the hydrogeologic units onshore and several miles offshore. This three-dimensional hydrogeologic model was constructed as part of a U.S. Geological Survey Groundwater Resources Program study of groundwater availability in the Northern Atlantic Coastal Plain (NACP) aquifer system, including parts of New York, New Jersey, Delaware, Maryland, Virginia, and North Carolina....

The U.S. Geological Survey New Jersey Water Science Center (USGS NJWSC) in cooperation with the New Jersey Department of Environmental Protection (NJDEP) has assembled this data release in support of ongoing USGS and NJDEP evaluations related to the occurrence and distribution of elevated trace elements, particularly arsenic (As) and vanadium (V), in Inner Coastal Plain soils and sediments of New Jersey. The data for four sediment cores are presented, and the data types include: 1. Site locations and general characteristics for the four sediment cores collected during the study; 2. Lithologic descriptions of each sediment core; 3. Portable handheld X-ray fluorescence (pXRF) data for each sediment core (every 6...

A third revision of the New Jersey Coastal Plain (NJCP) groundwater flow model, using MODFLOW-2005 (version 1.12.00), was completed to maintain the model’s usefulness for water-resource managment and development. The regional groundwater-flow model was initially developed for the U.S. Geological Survey (USGS) Regional Aquifer System Analysis (RASA) program. Periodic revision of the model is required as the result of changing hydrologic stresses, different and more complex water management needs, and increased knowledge of hydrologic conditions. The RASA model was initially constructed in the 1980’s as a quasi-3D model with 10 aquifers. The 9 intervening confining units were simulated using vertical leakage parameters...
