A steady state numerical groundwater flow model has been calibrated to characterize the spatial distribution of a key hydraulic parameter in a crystalline aquifer in southwestern Ghana. This was to provide an initial basis for characterizing the hydrogeology of the terrain with a view to assisting in the large scale development of groundwater resources for various uses. The results suggest that...

The spatial heterogeneity of dissolved arsenic (As) concentrations in shallow groundwater of the Bengal Basin has been attributed to transport of As (and reactive carbon) from external sources or to the release of As from within grey sand formations. We explore the latter scenario in this detailed hydrological and geochemical study along a 300 m transect of a shallow aquifer extending from a gr...

We optimize groundwater management in the presence of marine consequences of submarine groundwater discharge (SGD). Concern for marine biota increases the optimal steady-state head level of the aquifer. The model is discussed in general terms for any coastal groundwater resource where SGD has a positive impact on valuable near-shore resources. Our application focuses of the Kona Coast of Hawai’...

Surface water and groundwater systems are connected with the head gradient between the river and the nearby aquifer controlling the magnitude and direction of the exchange flux between the two systems. The direction of the flux dictates whether the river gains water from the nearby aquifer, or loses water to it. The exchange between groundwater and rivers is a key component influencing not only...

Problem statement: Making iron ore is one of the largest mining projects in south east of china. Due to the development of mining activities in that site, it has become necessary to increase the depth of exploration. Increase the exploration depth makes the mining tunnels subjected to the karst water inrush. Approach: A hydrological and a hydrogeological model for the Makeng area have been deve...

r a 200 .004 esent ad Geoscien ox X, A +1 512 4 kherjee@ Summary Samples of deep groundwater, river water and rainwater were collected for dO and dH analyses from an area of 22,000 km in the arsenic-affected districts of West Bengal, India, in order to examine groundwater recharge. A plot of dO versus dH of groundwater falls subparallel to the constructed local meteoric water line (dH = 7.2 dO ...

We analyze the management of a coastal aquifer under seawater intrusion using distributed control methods. The aquifer’s state is taken as the water head elevation, which varies with time and in space since extraction, natural recharge and lateral water flows vary with time and in space. The water head, in turn, induces a temporalspatial seawater intrusion process, which changes the volume of f...

Water is a limiting factor for economic and social development in most arid semi-arid regions on Earth. The deliberate recharge of depleted aquifer storage later recovery, known as managed (MAR), an important tool water management sustainability . Increasing stresses groundwater subsequent overdrafts have sparked the several advanced MAR technologies, including soil treatment (SAT). SAT method ...
