A phreatic aquifer ( also called unconfined aquifer，water table aquifer) is one in w hich a w ater table ( phreatic surface ) serves as its upper boundary. Actually，above the phreatic surface，w e have a capillary fringe w hich is often neglected in groundw ater studies. A ...
The current knowledge on thermal water resources in carbonate rock aquifers is presented in this review, which also discusses geochemical processes that create reservoir porosity and different types of utilisations of these resources such as thermal baths, geothermal energy and carbon dioxide (CO2) seq...
At the same time, aquifer storage replenishment through natural or managed recharge made occurs at a slower rate than its exploitation in such regions6. The imbalance between groundwater recharge (GWr) and the combination of natural rates of discharge and anthropogenic GW withdrawal have resulted in...
In a coastal aquifer the presence of seawaters at the base of fresh groundwaters and mixing processes between these two types of waters are the additional factors which influence temperature distribution. In fact the residence times of salt waters are generally much longer than those of fresh ...
Uptake of uranium (U) by secondary minerals, such as carbonates and iron (Fe)-sulfides, that occur ubiquitously on Earth, may be substantial in deep anoxic environments compared to surficial settings due to different environment-specific conditions. Yet,
EC and TDS are predicted because they are the most important water quality indicators. Predicting the electrical conductivity of water provides valuable information about its purity or contamination. The electrical conductivity of water is directly related to the dissolved ions or salts in the water. ...
decades to a level which is today close to the natural background. Due to the low tritium concentration today, the focus is more and more on the relationship between tritium (3H) and its daughter product helium (3He). Stable environmental isotopes such as18O and deuterium (2H) are used ...
A comprehensive assessment of water security can incorporate several water-related concepts, while accounting for Blue and Green Water (BW and GW) types de... Duke B. B. Rodrigues,HV Gupta,EM Mendiondo - 《Water Resources Research》 被引量: 32发表: 2015年 Impact of climate changes during ...
38. The ability of ML models to model groundwater salinity has been demonstrated via the establishment of a linear or non-linear relationship between water salinity and its control parameters (such as water table, evaporation, and distance to saltwater bodies) and using those relationships for the...
and aquifer minerals. Chloro-Alkaline indices (CAIs) were used to study cation exchange processes between the groundwater and its host environment at stagnancy and/or during groundwater travel. The Gibbs ratio 1 values were found to range from 0.26 to 0.94 and Gibbs ratio 2 values ranged from...
