Groundwater exploration in crystalline basement aquifers such as the Houtriver gneiss formation Limpopo province of South Africa is often described complex. This because groundwater availability largely a consequence interaction several processes related to recharge, underlying geological features and fracture connectivity aquifer rock matrix. In this study, an integration geophysical investiga...

Seawater intrusion, Coastal aquifer. 14Coastal zones, also referred to as the land-sea interface, are dynamic zones where terrestrial 17 freshwater biogeochemically interacts with seawater. have been recognized be 18 increasingly vulnerable contamination due dense human populations and anthropogenic 19 activities (Michael et al., 2017). Groundwater-seawater exchange is one of most important 20 ...

Acid resins are residues characterised by elevated concentrations of hydrocarbons and trace elements, which were produced by mineral oil industries in Central Europe during the first half of the last century. Due to the lack of environmental legislation at that time, these wastes were dumped into excavated ponds in public areas without further protection. In this work, the long-term effects of ...

Nitrogen (N) inputs to the world’s aquatic ecosystems have increased over the past 100 years. Riparian zones and other wetlands are known to remove N from ground and surface waters before they enter lakes and streams. However, the effect of riparian wetlands on water quality has been shown to differ dramatically among sites. Sources of landscape variation in riparian N dynamics have been poorly...

This paper presents a machine learning method to map groundwater potential in crystalline domains. First, spatially-distributed set of explanatory variables for occurrence is compiled into geographic information system. Twenty classifiers are subsequently trained on sample 488 boreholes and excavated wells region eastern Chad. process includes collinearity, cross-validation, feature elimination...

the focus of this research work is on the determination of the impact of mining on the groundwater quality in the historical mining region of sw ashanti region in ghana. this work describes the characteristics of the groundwater chemistry and pollution of the aquifer in the gold-ore bearing formation, which is highly weathered and fractured. the fractures control the permeability and depth of t...

Disposal of saline drainage water is a significant problem for irrigated agriculture. One proposal is to recycle drainage water to irrigate salt tolerant crops until the volume has been reduced sufficiently to enable final disposal by evaporation. Part of this concept requires in-situ crop water use from shallow groundwater; and data is needed to quantify the potential use of groundwater by alt...
