The Spectral Induced Polarization (SIP) is a promising electrical method, which can be used to predict the saturated hydraulic conductivity of consolidated and unconsolidated porous media. It is important to investigate how the SIP response is affected by the shape and distribution of ... En savoir plus

The calibration of groundwater models is usually limited by the scarcity of direct hydraulic data. The estimation of heterogeneous distribution of hydraulic properties can be improved through a joint or coupled inversion in which the calibration dataset is complemented with geophysical ...

Controlling the odiferous landfill gas (LFG) [e.g., Hydrogen sulfide (H2S)] emission is an important environmental issue during operating a municipal solid waste (MSW) landfill. A combination of LFG collection system and landfill cover has been an adapted method to mitigate the issue ... En savoir plus

Municipal Solid Waste (MSW) landfills typically experience significant settlement associated with various multi-physical factors such as waste property, placement timing, total height, and environmental conditions such as temperature and saturation throughout the lifetime of the ... En savoir plus

In a pumping test the drawdown of the water table in a piezometer is recorded, as response to pumping from a nearby well. Pumping tests belong into the common toolbox of hydro-geologists, used to obtain basic parameters for aquifer characterization. There are various approaches to ... En savoir plus

Smouldering is flameless combustion which depends on an exothermic surface reaction occurring within a porous medium. It is harnessed by engineers to destroy organic liquid wastes in soil as the technology Self-sustaining Treatment for Active Remediation (STAR). During this remediation ... En savoir plus

Modeling of fractured porous media systems is currently of high interest in various academic and applied fields, mainly in the geological and material sciences. The very different scales of the region of an application case on the larger end and the fracture on the lower end pose a ... En savoir plus

The unconventional shale gas reservoirs have a major contribution to hydrocarbon production in recent years. The hydraulic stimulation technique is being used to enhance the productivity of the target reservoirs. The drilled wellbore and existing natural fractures in the host rocks have ... En savoir plus

Subduction, the process through which the cold and dense oceanic lithosphere sinks into the highly viscous mantle, is the main driving force of plate tectonics and is important for recycling the Earth's materials. Active subduction has not been observed in any other planet in our solar ... En savoir plus

COMSOL Multiphysics® is used in various engineering fields and has recently been introduced as an efficient tool to solve certain geophysical problems. We used this software to study the mechanisms associated with the buckling formation at a plate-tectonic scale on Earth. Buckling is not ... En savoir plus
