Transfer function-noise modeling and spatial interpolation to evaluate the risk of extreme (shallow) water-table levels in the Brazilian Cerrados [PDF]

open access: yes
Water regimes in the Brazilian Cerrados are sensitive to climatological disturbances and human intervention. The risk that critical water-table levels are exceeded over long periods of time can be estimated by applying stochastic methods in modeling the ...

Dilemma of Spent Geothermal Water Injection into Rock Masses for Geothermal Potential Development

open access: yesEnergies
The global shift towards the use of renewable energy is essential to ensure sustainable development, and geothermal energy stands out as a suitable option that can support various cascading projects. Spent geothermal water (SGW) requires proper treatment

Application of Golden Sine Algorithm in Hydrogeological Parameter Optimization

open access: yesRenmin Zhujiang, 2020
To improve the accuracy of hydrogeological parameters, this paper conducts the simulationverification of golden sine algorithm (Gold-SA) algorithm by six standard test functions andcompares the simulation results with that of the particle swarm optimization (PSO) algorithm, andtaking two pumping test data as examples, optimizes two key parameters, i.e.

Hydrogeological model of Mijas mountain aquifers under different climate conditions (Málaga, Spain) [PDF]

open access: yes, 2017
Carbonate aquifers represent an important source of freshwater, both for urban and agricultural uses. This is particularly true in semiarid regions, where intensive pumping has often led to aquifer overexploitation.

Low‐Rank Geostatistical Inversion for Spatiotemporal Heterogeneity of Aquitard Hydraulic Parameters

open access: yesWater Resources Research
Many hydrogeological processes are intricately linked to both the spatial heterogeneity and temporal dynamics of the involved parameters. The variability in hydrogeological parameters across both space and time domains is defined as the spatiotemporal ...

Quick analysis of the characteristic hydrogeological parameters of an aquifer, using empirical formulas and the implementation of the clay substrate map: the case study of the shallow aquifer of the S. Eufemia Lamezia plain (Central Calabria - Italy).

open access: yesAcque Sotterranee, 2018
In Calabria, there are few works of quantitative hydrogeology. Therefore, the present study aims to provide a contribution to the hydrogeological knowledge of the region and, in particular, of the shallow aquifer of the S. E. Lamezia plain, characterized

Geostatistics as a tool to improve the natural background level definition: An application in groundwater [PDF]

open access: yes, 2017
The Natural Background Level (NBL), suggested by UE BRIDGE project, is suited for spatially distributed datasets providing a regional value that could be higher than the Threshold Value (TV) set by every country.
