Numerical Simulation of Bank Protection Structure Deformation due to River Level Fluctuations

R. Hu [1], Y. Xing [1],
[1] School of Earth Science and Engineering, Hohai University, Nanjing, China

In this study, based on a bank protection structure engineering at Yangtze River, a 2D water-soil coupling model is established, in which the influence of water level fluctuation on groundwater seepage and soil shear strength is considered. According to the water level measured data of ... En savoir plus

Effect of Groundwater Flow on the Subsurface Temperature within Crystalline Rocks of Southern Norway

Y. P. Maystrenko [1], O. Olesen [1],
[1] Geological Survey of Norway (NGU), Trondheim, Norway

The subsurface thermal regime has been investigated in boreholes from southern Norway. During the purely conductive 2D thermal modeling, the COMSOL Heat Transfer for Solids interface has been used to simulate heat transfer by heat conduction. COMSOL physics interfaces Heat Transfer in ... En savoir plus

[1]Amphos21 Consulting, Barcelona, Spain
[2]Swedish Nuclear Fuel and Waste Management Co., Stockholm, Sweden

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 ... En savoir plus

An Innovative Reactive Transport Modeling Approach for the Chemical Evolution of a HLW Cell in the Callovo-Oxfordian Formation

J. Molinero[1], D. García[1], M. Grivé[1], A. Nardi[1]
[1]Amphos 21 Consulting, Barcelona, Spain

Andra (The French National Radioactive Waste Management Agency) envisages the safe disposal of High-Level Waste (HLW) and Intermediate-Level Long-Lived Waste (IL-LLW) in deep geological storage using a multi-barrier system. To ensure the containment of radioactivity, the principle of ... En savoir plus

Study of HVDC Grounding Systems Using Finite Element Methods

C. K. C. Arruda [1], A. A. Silveira [1], L. C. R. Vieira [1], F. C. Dart [1],
[1] CEPEL, Rio de Janeiro, RJ, Brazil

High Voltage Direct Current transmission (HVDC) is a suitable alternative for long distance transmission. During the years, the use of this technology has been increasing, which is one of the several reasons to improve methodologies in HVDC grounding systems. Unlike the usual approach ... En savoir plus

Modeling Magnetic Induction from Transient Events Impinging upon a Conducting Moon

H. Fuqua[1], G. Delory[1], I. de Pater[2], R. Grimm[3]
[1]University of California - Berkeley, Space Sciences Lab, Berkeley, CA, USA
[2]University of California - Berkeley, Berkeley, CA, USA
[3]Southwest Research Institute, Boulder, CO, USA

Electromagnetic sounding measurements utilize magnetic induction to constrain the interior geophysical properties of planetary bodies. Under some conditions, the Earth’s moon can be approximated by the response of a conducting sphere in a vacuum. Transient magnetic fields originating ... En savoir plus

Modeling of Biocalcification in Non-Saturated Conditions

B. Courcelles [1], C. Raymond-Poirier [1],
[1] École Polytechnique de Montréal, Montréal, QC, Canada

In the context of increasing demographic pressures around the world, soil improvement techniques constitute viable alternatives to expensive foundations. Among these techniques, the biocalcification of granular soils appears as a promising alternative relying on the formation of calcium ... En savoir plus

2-Dimensional Incompressible and Compressible Mantle Convection

Changyeol Lee[1]
[1]Faculty of Earth and Environmental Sciences, Chonnam National University, Gwangju, Republic of Korea

COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows ... En savoir plus

Magnetotelluric Response Distortion Over Rugged Topography

D. Rizzello[1], P. Canepa[1], E. Armadillo[1]
[1]DISTAV - University of Genova, Genova, Italy

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, ... En savoir plus
