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

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

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

Numerical Analysis of Shaft Resistance and Toe Resistance of a Pile in Unsaturated Soil

E. Evgin[1], J. A. Infante Sedano[1], Z. Fu[1]
[1]University of Ottawa, Ottawa, ON, Canada

A pile transfers structural load to the ground at the surface of its shaft and at its toe. In the calculation of these two components of load, both the deformation characteristics and the strength properties of the soil are needed. In unsaturated soils, matric suction changes the stress ... 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

Remote Sensing of Electromagnetically Penetrable Objects: Landmine and IED Detection

R. Eze [1], G. Sivulka [2], ,
[1] City University of New York - LaGuardia Community College, Long Island City, NY, USA
[2] Regis High School, New York, NY, USA

The detection, characterization, and classification of underground environmental hazardous objects [mines, IEDs, and other unexploded military hardware] is a worldwide problem that needs urgent attention and solution. While electromagnetic sensor technologies have been applied to ... En savoir plus

Implementation of a Modified Anisotropic Creep Model for Clays with Use of the Physics Builder

M. Karlsson [1], J. Yannie [1],
[1] Chalmers University of Technology, Gothenburg, Sweden

In this work a modified anisotropic creep model with structure for soft soils was implemented by using the Physics Builder. The model is validated against boundary value laboratory test such as undrained tri-axial tests and CRS (constant rate of strain) tests. The implemented user ... En savoir plus

Investigating the Impacts of Hydrogeological Parameters on DSI Efficiency through Numerical Simulation

Y. Jin[1], E. Holzbecher[1], S. Ebneth[2]
[1]Department of Applied Geology, GZG, Georg-August- University of Göttingen, Göttingen, Germany
[2]Hölscher Wasserbau, Haren, Germany

Düsensauginfiltration (DSI),‘nozzle-suction-infiltration’, is a new method for dewatering that avoids groundwater abstraction from the aquifer. Drawdown is achieved via pumping of groundwater at upper abstraction section, meanwhile, all the pumped water is injected through the same ... En savoir plus
