Few field measurements are available to constrain the diffuse discharge (or vertical leakage) component of the water balance of the Great Artesian Basin (GAB), even though numerical modelling indicates that it accounts for over half of the outflow of the GAB in South Australia. High leakage rates are observed along the southwestern margin of the GAB where the aquifer is close to the surface wit...

Groundwater salinization is considered as a major environmental problem in worldwide coastal areas, influencing ecosystems and human health. However, an accurate prediction of salinity concentration groundwater remains challenge due to the complexity processes its factors. In this study, we evaluate state-of-the-art machine learning (ML) algorithms for predicting identify We conducted study mul...

Policies surrounding energy development are frequently implemented in response to known or perceived problems. South Africa is a unique position develop prospective policies that build on knowledge gained from elsewhere. This paper provides analysis of hydrogeological risk pathways and vulnerability attributes advance anticipated shale gas operations the Karoo Basin Africa. The ‘hazard-pathways...

Abstract In 2017, a comprehensive review of groundwater resources in Jordan was carried out for the first time since 1995. The change levels between 1995 and 2017 found to be dramatic: large declines have been recorded all over country, reaching more than 100 m some areas. most affected areas are those with large-scale groundwater-irrigated agriculture, but that only used public water supply al...

An abandoned open green space in the urban setting of Municipality Pisa (Tuscany, Italy) has been designed for renewal to foster development recreational activities and improve lives surrounding communities. However, geochemical site characterization revealed Pb, Cu, Zn Hg concentrations soil exceeding thresholds imposed by Italian regulations residential use. Cu contents likely reflect effects...

Abstract: Permeable reactive barriers installed at a gold mine and at a chemical manufacturing facility have been effectively remediating arsenic contaminated groundwater since they were installed in 2002. At the mine site, the PRB is pilot scale and uses a reactive mixture consisting of zero valent iron filings and organic carbon derived from locally available wood chips. For experimental cont...

To investigate the drainage conditions that might be expected to develop beneath soft-bedded ice sheets, we modeled the subglacial hydrology of the James Lobe of the Laurentide Ice Sheet from Hudson Bay to the Missouri River. Simulations suggest the James Lobe had little effect on regional groundwater flow because the poorly conductive Upper-Cretaceous shale that occupies the upper layer of the...

Abstract Groundwater resources in the south Darb El Arbaein are currently threatened by agricultural impact and rock water interaction associated with over exploitation. Planning of Nubian sandstone aquifer is required, especially this new invest area. It implemented GIS to establish vulnerability areas evaluate protocol plans for hydrogeological parameters soil. The TDS concentration ranged fr...
