Paul Barlow
Paul Barlow is a Chief of the Hydrologic Interpretive Branch in the New England Water Science Center.
As Chief of the Hydrologic Interpretive Branch, New England Water Science Center, Paul manages a diverse team of scientists involved in a wide range of water-resources investigations spanning environmental, watershed, and urban hydrology; integrated water-resources modeling; and statistical and geospatial analyses. His technical work has focused on numerical modeling of coupled groundwater/surface-water flow systems and the application of mathematical optimization methods to problems in groundwater management, including streamflow depletion caused by groundwater withdrawals.

GWM is a Ground?Water Management Process for the U.S. Geological Survey modular three?dimensional ground?water model, MODFLOW?2000. GWM uses a response?matrix approach to solve several types of linear, nonlinear, and mixed?binary linear ground?water management formulations. Each management formulation consists of a set of decision variables, an objective function, and a set of constraints. Three tAuthorsDavid P. Ahlfeld, Paul M. Barlow, Anne E. MulliganEffects of alternative instream-flow criteria and water-supply demands on ground-water development options in the Big River Area, Rhode Island
Transient numerical ground-water-flow simulation and optimization techniques were used to evaluate potential effects of instream-flow criteria and water-supply demands on ground-water development options and resultant streamflow depletions in the Big River Area, Rhode Island. The 35.7 square-mile (mi2) study area includes three river basins, the Big River Basin (30.9 mi2), the Carr River Basin (whAuthorsGregory E. Granato, Paul M. BarlowEvolving issues and practices in managing ground-water resources: Case studies on the role of science
Hydrologic stresses throughout the 20th century and presently (2003) have caused the depletion and degradation of our Nation’s vital ground-water resources in many areas. Management strategies have been and are being implemented to optimize use of our ground-water resources with respect to achieving sustainability while mitigating the consequences of future withdrawals. The seven case studies presAuthorsDevin L. Galloway, William M. Alley, Paul M. Barlow, Thomas E. Reilly, Patrick TucciHydrogeology and Simulated Effects of Ground-Water Withdrawals in the Big River Area, Rhode Island
The Rhode Island Water Resources Board is considering expanded use of ground-water resources from the Big River area because increasing water demands in Rhode Island may exceed the capacity of current sources. This report describes the hydrology of the area and numerical simulation models that were used to examine effects of ground-water withdrawals during 1964?98 and to describe potential effectsAuthorsGregory E.

No abstract available.AuthorsPaul M. BarlowBibliography on the occurrence and intrusion of saltwater in aquifers along the Atlantic Coast of the United States
Freshwater aquifers along the Atlantic coast of the United States are vulnerable to the intrusion of saltwater from saline waters that bound the aquifers along their seaward margins. Incidences of saltwater intrusion have been documented along the Atlantic coast for more than 100 years. This report provides a bibliography of published literature relating to the occurrence and intrusion of saltwateAuthorsPaul M. Barlow, Emily C. WildNumerical-simulation and conjunctive-management models of the Hunt-Annaquatucket-Pettaquamscutt stream-aquifer system, Rhode Island
Numerical-simulation and optimization techniques were used to evaluate alternatives for the conjunctive management of ground- and surface-water resources of the Hunt-Annaquatucket-Pettaquamscutt stream-aquifer system in central Rhode Island. Ground-water withdrawals from the Hunt-Annaquatucket-Pettaquamscutt aquifer exceeded 8 million gallons per day during months of peak water use during 19939AuthorsPaul M. Barlow, David C. DickermanBalancing Ground-Water Withdrawals and Streamflow in the Hunt-Annaquatucket-Pettaquamscutt Basin, Rhode Island
Ground water withdrawn for water supply reduces streamflow in the Hunt-Annaquatucket-Pettaquamscutt Basin in Rhode Island. These reductions may adversely affect aquatic habitats. A hydrologic model was prepared by the U.S. Geological Survey in cooperation with the Rhode Island Water Resources Board, Town of North Kingstown, Rhode Island Department of Environmental Management, and Rhode Island EconAuthorsPaul M. Barlow, David C. DickermanWTAQ: A Computer Program for Calculating Drawdowns and Estimating Hydraulic Properties for Confined and Water-Table Aquifers
The computer program WTAQ calculates hydraulic-head drawdowns in a confined or water-table aquifer that result from pumping at a well of finite or infinitesimal diameter. The program is based on an analytical model of axial-symmetric ground-water flow in a homogeneous and anisotropic aquifer. The program allows for well-bore storage and well-bore skin at the pumped well and for delayed drawdown reAuthorsPaul M. Barlow, Allen F. MoenchUse of computer programs STLK1 and STWT1 for analysis of stream-aquifer hydraulic interaction
Quantifying the hydraulic interaction of aquifers and streams is important in the analysis of stream base fow, flood-wave effects, and contaminant transport between surface- and ground-water systems. This report describes the use of two computer programs, STLK1 and STWT1, to analyze the hydraulic interaction of streams with confined, leaky, and water-table aquifers during periods of stream-stage fAuthorsLeslie A.
