Layered geospatial PDF 7.5 Minute Quadrangle Map. Layers of geospatial data include orthoimagery, roads, grids, geographic names, elevation contours, hydrography, and other selected map features. This map is derived from GIS (geospatial information system) data. It represents a repackaging of GIS data in traditional map form, not creation of new information. The geospatial data in this map are from selected National Map data holdings and other government sources.

Digital flood-inundation maps for coastal communities within Cape May County in New Jersey were created by water surfaces generated by an Advanced Circulation hydrodynamic (ADCIRC) and Simulating Waves Nearshore (SWAN) model from the Federal Emergency Management Agency (FEMA) Region II coastal analysis and mapping study (Federal Emergency Management Agency, 2014). Six synthetic modeled tropical storm events from a library of 159 events were selected based on parameters including landfall location or closest approach location, maximum wind speed, central pressure, and radii of winds. Two storm events were selected for the tide gage providing two "scenarios" and accompanying inundation-map libraries. The contents...
Three existing groundwater flow models, using MODFLOW-2000, SEAWAT, and SHARP model codes, were used by the U.S. Geological Survey (USGS) to determine the effects of increased withdrawals, and shifts of withdrawals between 2 aquifers, on the limited water resources in the Cape May County, New Jersey. Saltwater intrusion and declining water levels have been a water-supply problem in Cape May County for decades. Several communities in the county have only one aquifer from which freshwater withdrawals can be made, and that sole source is threatened by saltwater intrusion and (or) substantial declines in water levels caused by groundwater withdrawals. Growth of the year-around and summer tourism populations have caused...

A three-dimensional groundwater-flow model (MODFLOW-2000 ) of the Kirkwood-Cohansey aquifer system, Rio Grande water-bearing zone, and Atlantic City 800-foot sand in the Great Egg Harbor and Mullica River Basins, N.J. was developed to simulate the effects of withdrawals on streamflow and groundwater supply. Increasing groundwater withdrawals from the unconfined Kirkwood Cohansey aquifer system is a major concern because of the potential for streamflow depletion and the resulting ecological effects on aquatic habitats, wetlands, and vernal ponds. In the confined Atlantic City 800-foot sand aquifer water levels have been steadily declining and most of the groundwater withdrawn from the Atlantic City 800-foot sand...
