Earthfx Incorporated developed a preliminary regional-scale groundwater model for the entire Grand River Conservation Authority area. The objective of the study was to better understand regional groundwater flow in the GRCA and evaluate the interaction between the river and the various aquifer systems in the basin. A key aspect of the study was the integration of multiple smaller-scale models ...
In geophysics, surface NMR methods can be used to non-invasively map groundwater aquifers and borehole logging NMR tools can be used to obtain high-resolution estimates of hydrogeologic properties downhole. ...
A new, animated map of California, created with 18 years of interferometric synthetic aperture radar (InSAR) and GPS aquifer data, illustrates the cycle of compaction and expansion like never before. ...
Groundwater withdrawn from the Chicot, Evangeline and Jasper aquifers, within the Gulf Coast aquifer system, has been the primary source of water for these uses since the early 1900s. ...
It will include a comprehensive assessment of aquifers, including mapping potential sites for brackish groundwater wells. ...
In this research, a novel approach for environmental risk assessment on groundwater pollution is applied. By combination of aquifer vulnerability DRASTIC map, pollution severity and prioritizing of the plain regions by the TOPSIS method, more sensitive regions of Qazvin aquifer in Iran are identified. In the first step, seven hydro-geological ...
The coastal aquifers system of Sfax Agareb Chaffar Mahres (Southern Sfax) located in the central east of Tunisia is well known for population growth and industrial development. ...
The aims of this paper are to determine the aquifer vulnerability of Sefid-Dasht, in Chaharmahal and Bakhtiari province, Iran, using the DRASTIC model. ...
Mineralisation exploration • Determining the size of ore deposit; • Determining the developing direction of ore deposit; • Mapping the distribution of ore deposit. Engineering applications • Determining the thickness of shallow formations; • Mapping basement rocks and their lithology; • Evaluation building foundation ...
Thus, as the radar antenna is slowly towed across the surface, a continuous cross-sectional "picture" of subsurface conditions is generated. GPR can be used for mapping geologic strata, aquifers, aquicludes. voids, shallow, bedrock units and fractures, site clearance for drilling, mapping utilities and re-bar, locating underground storage tanks, ...
As part of the investigation, GeoView was tasked to map the lateral and vertical extent of the freshwater lenses (aquifers) on the island using EM and ERI and compare the results to previous studies. A methodology was developed so that future researchers using EM tools could easily document changes to the shalllow freshwater aquifer. ...
Big Pine Key, FL is one of the primary areas of investigation because of extensive previous work and that a large portion of the island is a National Wildlife Refuge and therefore not subject to future development. GeoView was tasked to map the lateral and vertical extent of the freshwater lenses (aquifers) on the island using EM and ERI and compare the results ...
It is incredibly shortsighted to be building coal-fired power plants in a country where climate change threatens to worsen water shortages. Overpumping aquifers is hard to stop, in part because it is invisible, only apparent once a well goes dry. In July, the Indian government belatedly announced that it would boost spending to map out the country's ...
The objectives of the study were to: (a) describe groundwater resource and socioeconomic settings for four selected aquifers; (b) describe governance arrangements for groundwater management in Kenya; and (c) identify the relevance of these arrangements for planning and implementing climate change mitigation measures. ...
Example uses include decision support in resource management, a scientific application for aquifer mapping, and a commercial application for drill site selection. ...
The basic answer to both questions is communications. The plume, or plume map, is the most widely used method to summarize site investigation data for ground water into a comprehensive picture of what is occurring at a site. Plume maps are drawn for aquifers as a whole, for individual constituents, or for groups of constituents with common ...

One of the major concerns most commonly found in coastal aquifers, is the induced flow of salt water into fresh water aquifers caused by groundwater development, known as salt water intrusion. ...
