Abstract Uranium (U) is formed by the interaction of groundwater in aquifer and surrounding rocks. The area chosen for this study a hard rock terrain various lithology South India, which releases U affect quality. Hence, was conducted to understand geochemistry temporal variations with respect saturation state minerals different seasons namely Pre-monsoon (PRM), Northeast monsoon (NEM), Southwe...

Groundwater storage (GS) is the major water resource for vegetation in drylands. Thus, positive relationships between vegetative growth condition (VGC) and GS are expected Since mining-induced dewatering tends to deplete surrounding mine sites, VGC should become less favorable due a shortage of accessible water. However, quantitative analysis repealed opposite. We found that global annual miner...

Treated wastewater discharged from more than 400 onsite wastewater treatment systems (OWTS) near the Civic Center area of Malibu, California, 40 km west of downtown Los Angeles, composes 28% of the recharge to a 3.4 km(2) alluvial aquifer. On the basis of δ(18) O and δD data, the fraction of wastewater in some samples was >70%. Ammonium and nitrate concentrations in water from 15 water-table we...

Groundwater belongs to the category of strategic minerals, along with hydrocarbon resources, so supply drinking water will become one urgent problems modern society. The management groundwater resources and their protection is a very complicated task, especially in border areas where neighboring states jointly exploit aquifers. problem transboundary management, particular groundwater, has been ...

Groundwater irrigation has been instrumental in enhancing food security and, arguably, in mitigating poverty in developing countries. Groundwater provides timely irrigation, leading to an increase in crop intensity and productivity (Food and Agriculture Organization 2003). But groundwater irrigation also contributes the most to the depletion of groundwater reserves. Countries with significant g...

Groundwater from the coastal aquifers north of Chennai is being pumped since 1981 to meet the increasing demand. Huge groundwater extracting in the coastal aquifers groundwater causes lowering of groundwater table which led to seawater intrusion. The objective of this study is to assess the behavior of this aquifer to seawater intrusion under different hydrological stresses by groundwater model...

Fluid flow through porous media is of great importance for many natural systems, such as transport of groundwater flow, pollution transport and mineral processing. In this paper, we propose and validate a novel finite volume formulation of the lattice Boltzmann method for porous flows, based on the Brinkman–Forchheimer equation. The porous media effect is incorporated as a force term in the lat...
