Characterization and modeling of land subsidence due to groundwater withdrawals from the confined aquifers of the Virginia Coastal Plain
… compaction appear to be correlated with withdrawals of water from confined aquifers. One-dimensional vertical compaction modeling indicates that the measured compaction is the result of nonrecoverable hydrodynamic consolidation of the fine-grained confining units and interbeds as well as …

GROUNDWATER WITHDRAWAL ESTIMATION USING INTEGRATED REMOTE SENSING PRODUCTS AND MACHINE LEARNING
… various critical components affecting the globe. Groundwater, which comprises the world's 30% freshwater, is one such key component of the global water resources and supplies nearly half of the global drinking water.</p> <p>Despite groundwater overdraft in many parts of the world, including the …

Hydrologic and hydraulic assessment of artificial recharge in the Sparta Aquifer of Union County, Arkansas
Groundwater pumping from the Sparta aquifer in Union County, Arkansas, has long exceeded natural recharge, threatening the regional water supply. An alternative water-supply project, completed in 2004, now provides treated surfacewater to local industries. This conjunctive use of surface- and …

Water Resources Impacts of Uranium Mining in the San Juan Basin, New Mexico
… research was to improve understanding of the groundwater impacts of uranium mining in the San Juan Basin by estimating the volumetric amount of water removed from the underlying Westwater Canyon member aquifer. This was achieved by modeling a conceptual mine that is based on the physical …

Assessing Aquifer Vulnerability to Seawater Intrusion : Application of the GALDIT-Index to the Emilia-Romagna Coastline.
… (SWI) in coastal aquifers due to excessive groundwater withdrawals (for civil, agricultural and industrial purposes) has become a major concern affecting a large number of coastal aquifers worldwide. This trend is expected to grow in the very near future due to the expected sea-level rise …

Groundwater depletion embodied in transfers and exports of the United States
… products all over the world. Irrigation from groundwater resources is increasingly important in agricultural production in the US. Groundwater withdrawals for irrigation have nearly tripled since records began in 1950, even accounting for recent water use efficiency gains. Increased reliance …

Machine Learning methods for providing groundwater management insights in semi-arid alluvial aquifers
Accurate regional groundwater level (GWL) forecasting is critical for evaluating the impacts of groundwater withdrawals on water resource sustainability, especially during droughts. A lack of hydrogeological data often makes it challenging to develop water balance models that forecast the impacts …

A GIS Approach to Modeling Groundwater Levels in the Mississippi River Valley Alluvial Aquifer
<p>Groundwater depletion, a subject of growing concern for a significant portion of Arkansas, may lead to future economic challenges for the Arkansas Delta region. The Mississippi River Valley Alluvial Aquifer is the uppermost aquifer and features the largest groundwater capacity in the Mississippi …

Groundwater Modeling and Hydrogeological Parameter Estimation: Potomac Aquifer System, SWIFT Research Center
… the Potomac Aquifer System due to unsustainable groundwater withdrawals. At the SWIFT Research Center (SWIFTRC) in Nansemond, VA, a pilot testing well (TW-1) has been implemented to help determine the feasibility of full-scale implementation. The pumping data from TW-1 and observation head data …

Using MODFLOW to Predict Impacts of Groundwater Pumpage to Instream Flow: Upper Kittitas County, Washington
… 1960, new water demands have been met through groundwater withdrawals, with most groundwater users holding a later priority date than senior and junior surface water users. As a result of the discussions surrounding this issue, the Upper Kittitas Groundwater Rule has been in effect since 2010. …

Base Flow Recession Analysis for Streamflow and Spring Flow
… streams dominate the flowing streams and groundwater hydraulics governs the recession behavior. The ephemeral stream densities vary from arid regions to humid regions. Therefore, the characteristics of transition flow across the climate gradients are also tested in 40 watersheds. It is …
