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 results from two steady-state simulations, determine flow paths and travel times to near-shore wells screened in the unconfined Kirkwood-Cohansey...
A three-dimensional groundwater flow model (MODFLOW2000) of the Atlantic Coastal Plain aquifers and confining units was developed to evaluate groundwater availability and to forecast the potential effects of climate change on groundwater levels in the study area. Two existing groundwater flow models that simulated flow and water use in the Coastal Plain aquifers of North Carolina (NC), South Carolina (SC), and parts of Georgia and Virginia, were combined and updated to provide a single model. Revisions to the model incorporated additional hydrogeologic, geologic, water-level, and water-use data and hydrogeologic inconsistencies at the NC-SC border reconciled since the development of the previous models. The new...
A groundwater-flow model that was previously developed by the U. S. Geological Survey of Ocean County, N.J. (https://doi.org/10.3133/sir20165035) was used in an analysis of groundwater flow in the Kirkwood-Cohansey aquifer system and deeper confined aquifers that underlie the Barnegat Bay-Little Egg Harbor (BB-LEH) watershed and estuary. The analysis used a MODFLOW2005 simulation, in conjunction with the particle-tracking computer program MODPATH (Pollock, 1994), to delineate particle flow paths, the discharge location of each particle, and estimate the travel time along flow paths to the BB LEH estuary and streams within the BB-LEH watershed. This study conducted by the USGS, in cooperation with the Barnegat Bay...
