This study presents an approach for obtaining limited sets of realizations of hydraulic conductivity (K) of multiple aquifers using simulated annealing (SA) simulation and spatial correlations among aquifers to simulate realizations of hydraulic heads and quantify their uncertainty in the Pingtung Plain, Taiwan. The proposed approach used the SA algorithm to generate large sets of natural logar...

Abstract Groundwater from the Quaternary Mississippi River Valley Alluvial (MRVA) aquifer in southeastern Arkansas (SE AR), USA, has higher salinity compared to other MRVA groundwater. Previous studies have argued for infiltration of evaporated soil water as a primary source elevated salinity, although seepage local rivers and deep groundwater sources also been considered. Geochemical isotope d...

Abstract Coastal groundwater reservoirs are sensitive to the complicated evolution of marine transgressions and regressions in river delta regions. We integrated hydrogeological investigation hydrogeochemical data with numerical modeling assess system Pearl River Delta’s aquifer (in southeastern China). studied effects flow dynamics redox conditions on biogeochemical processes nutrients regiona...

Tidal fluctuations in a leaky confined coastal aquifer are damped significantly due to leakage into an overlying phreatic aquifer. Jiao and Tang [1999] presented an analytical solution to a simple model describing this phenomenon. Their solution assumes that the tidal fluctuations in the overlying phreatic aquifer are negligible (i.e., a static phreatic aquifer). Here we examine dynamic effects...

Storage of carbon dioxide (CO2) in saline aquifers is a promising tool to stabilize the anthropogenic CO2 emissions. At reservoir conditions, injected buoyant with respect ambient fluid (brine) and spreads as current laterally toward top cap rock aquifer, potential risk leakage into upper aquifer layers. However, partially soluble brine resulting mixture (CO2 + brine) denser than both starting ...

The Wajid aquifer is considered the main source of water for drinking and irrigation in Wadi Al-Dawasir Najran, southern region Saudi Arabia. This has been used since 1960s, due to expansion agricultural activities, overexploited. study aims understand origin, hydrochemical processes groundwater shallow unconfined, deep confined parts area. In-situ parameters (pH, temperature, EC, TDS) were mea...

The Pannonian basin is a major geothermal heat system in Central Europe. Its peripheral basin, the East Slovakian an example of structure with linear, directed flow ranging from 90 to 100 mW/m2 west east. However, use source limited by several critical tectono-geologic factors: (a) Tectonics, and associated disintegration aquifer block multiple deformations during pre-Paleogene, mainly Miocene,...
