First posted March 2, 2021 For additional information, contact: Director,Utah Water Science CenterU.S. Geological Survey2329 West Orton CircleSalt Lake City, Utah 84119-2047 Groundwater is a primary source of drinking water in northern County. The groundwater system recharged mainly from precipitation the adjacent Wasatch Mountains and infiltration streamflow. In 2004, withdrawals were estimate...
Mining throughout the Floridan aquifer system alters groundwater conditions. Determination of magnitude and extent of groundwater alterations in this regional karst aquifer system is difficult due to preferential flow paths, blasting, and widespread aquifer withdrawals and injections. Additionally, hydrologic models do not reveal subsurface impacts to the biotic environment, such as destruction...
the planning of water resources is based on the volume of water extracted from the aquifer and accurate estimate of this volume considerably helps to development. in this study, the bayesian networks model using continues and clustering structures was used to simulate the groundwater level of birjand aquifer. bayesian networks was calibrated with five input variables of aquifer recharge, water ...
Aquifer overexploitation could significantly impact crop production in the United States because 60% of irrigation relies on groundwater. Groundwater depletion in the irrigated High Plains and California Central Valley accounts for ~50% of groundwater depletion in the United States since 1900. A newly developed High Plains recharge map shows that high recharge in the northern High Plains result...

Groundwater also supplies fresh that supp...
Abstract Warming temperatures increase the evapotranspiration demand of crops, leading to an in irrigation and exacerbating water scarcity. Previous research relies on models requirements understand potential impacts climate change, but these have significant uncertainty ignore risk-averse behavior irrigators. Here we develop regression estimate how changes vapor pressure deficit precipitation ...
Karst regions, occupy approximately 25% of the land surface of the earth. Karst aquifers are often major sources of water supply in these areas. However, karst aquifers are generally considered to be particularly vulnerable to pollution and anthropogenic impacts. Large withdrawals of water in karst areas for municipal, agricultural, and industrial use may competitively affect water supply in su...
The increasing competition for water resources requires a better understanding of flows, fluxes, stocks, and the services and benefits related to water consumption. This paper explains how public domain Earth Observation data based on Moderate Resolution Imaging Spectroradiometer (MODIS), Second Generation Meteosat (MSG), Tropical Rainfall Measurement Mission (TRMM) and various altimeter measur...
Although Iran's Ghaen Plain provides saffron to much of the world, no regional groundwater quality (GQ) assessment has yet been undertaken. Given the region's potential for saltwater intrusion and heavy metal contamination, it is important to assess the GQ and determine its main probable source of pollution (MPSP). Such knowledge would allow for informed mitigation or elimination of the potenti...
www.jogh.org • journal of global health / December, 2011 • Vol. 1 No. 2 135 Water resources of a country constitute one of its vital assets. India receives an average of 4000 billion cubic meters of rainfall every year, confined to the monsoon season (June through September). Unfortunately, due to lack of storage and crumbling infrastructure, only 18% can be used (1). Apart from the water avail...
