The authors present a closer look on the Single-Well Injection-Withdrawal Experiment (SWIW) or Push-Pull Experiments and its ability to determine the groundwater velocity, as one of the major parameters concerning reservoir management and underground reservoir characterization. The flow field is modeled using analytic and numerical solutions. Different modes like Darcy-law, solute-transport and ...

We present an implementation of the Structural Mechanics module of COMSOL Multiphysics to model the state of stress associated with the emplacement of large volcanic edifices on the surface of a planet. These finite element models capture two essential physical processes: (1) Elastic flexure of the lithosphere beneath the edifice load, and (2) Pressurization of a magma-filled chamber that serves ...

Topographic effects on magnetotelluric responses may be severe on rugged terrains. Finite elements simulation is a valuable tool to quantify this effect, due to its capability to match real morphologies. To do the estimate of the distortion, the AC/DC Module of COMSOL has been employed, using a model of homogeneous resistivity on which a DEM (Digital Elevation Model) profile of the Deep Freeze ...

The percolation of water into soil can be modeled considering Darcy's Law in laminar flow. In this manner the key property is the coefficient of hydraulic conductivity. Its determination can be made through laboratory or field testing. One of the most known field tests used for determination of this property is the Slug Test. This test consists of a perforated well in the ground where a known ...

Bridge piers and abutments makeup the bridge substructure and transmit loads from the superstructure to the bridge foundation material (Figure 1). The bridge abutment serves three purposes: to provide vertical support to the bridge superstructure where the bridge ends, to connect the bridge with the approach roadway, and to retain roadway base materials. There are several types of abutment ...

Energy piles transfer the mechanical loads from buildings to the ground and serve as heat exchangers. Temperature changes in the ground influence its moisture content. This paper examines the effect of soil moisture content on the shaft resistance of a pile. Tests were carried out in the laboratory to determine the mechanical properties of an interface corresponding to various soil moisture ...

The Swedish Nuclear Fuel and Waste Management Company (SKB) operates the underground repository for low- and intermediate-level nuclear waste (SFR) located in Försmark, Sweden. An extension of the SFR is planned to accommodate mainly waste arising from the decommissioning of Swedish nuclear power plants. The long-term safety assessment for the SFR repository takes into account the future ...

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent treatment of the generated gases or liquids. Of all the decontamination methods, bioremediation appears to be the ...

Groundwater is a key factor affecting mine operations worldwide. On one hand, both underground and open pit mines need to pump out groundwater in order to proceed with mineral extraction and increase the stability of rock slopes. On the other hand, groundwater abstractions can produce undesired environmental and social impacts, which should be anticipated in the environmental impact assessments ...

Structural, morphological and ground deformation studies suggest that the eastern flank of Mt. Etna (eastern Sicily) is spreading seaward. According to the deep-seated spreading model, both the volcanic edifice and its uppermost basement are spreading eastwards because of magma inflation processes related to a dike complex located at a depth between the summit craters and the Valle del ...
