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...

The hydrogeological processes driving the hydrochemical composition of groundwater in alpine pristine aquifer system Port del Comte Massif (PCM) are characterized through multivariate statistical techniques Principal Component Analysis (PCA) and Gaussian Mixture Models (GMM) framework Compositional Data (CoDa) analysis. Also, Natural Background Levels (NBLs) for NO3 SO4 Cl evaluated, which spec...

A new method for the determination of permeability fields in highly heterogeneous aquifers is proposed. It stems from the known relations between soil electric resistivity and permeability. Several cut-offs are made to electric resistivity probability distribution. These cut-offs are heuristic estimates about what classes of values of one variable should relate to what classes of values of the ...

Karst hydrological models are widely used for simulating groundwater dynamics at the aquifer scale. However, modeling streamflow of a topographic catchment that is partially covered by karst rarely reported. This absence due to difficulties properly considering strong differences karstic and nonkarstic hydrodynamics widespread occurrence unclosed water balances in regions intercatchment flow (I...

Hydrogeological mapping is a key tool for groundwater resource management. Generally, hydrogeological maps focus mainly on porous or karst aquifer at large scale. In fractured-rock aquifer, the flow path not immediately deductible due to intrinsic complexity of fracture systems. Then, it crucial importance collecting complete dataset describing site interest: fault and strata patterns, geomorph...
