[1] Enviromental Research Laboratory, NCSR "Demokritos", Athens, Greece
[2] Environmental Hydrogeology Group, Utrecht University, The Netherlands

Immiscible two-phase flow in porous materials is a process of significant scientific and applied interest encountered in numerous technological applications related to energy and the environment (e.g. subsurface water flows, petroleum recovery, soil remediation and geologic carbon ... Read More

A Computational App for a Proper Evaluation of the Irrigation Effect Over the Aquifers

D. Sampietro [1], J. Molinero [1], E. Fernández [2],
[1] Amphos 21 Consulting S.L., Spain
[2] Grupo Tragsa - SEPI, Spain

A correct design and control of the irrigation cycles is very important for the correct and efficient grow of the crops. It is well known that a correct design of the irrigation cycles increases its efficiency and reduces the amount of water required. An important objective in the ... Read More

Radionuclide Transport Through Different Routes Near a Deposition Hole for Spent Nuclear Fuel

V-M.S. Pulkkanen[1]

[1]VTT, Technical Research Centre of Finland, Espoo, Finland

Radionuclide transport modeling is a part of the research concerning geological disposal of spent nuclear fuel. Typically, the transport models near a single deposition hole focus on the reactions of nuclides, while the model geometry and the flow of groundwater are often simplified. In ... Read More

Evaluation of CO2 Leakages From An Aquifer Storage

A. Thoraval[1], R. Farret[2], A. Cherkaoui[2], and P. Gombert[2]
[1]INERIS, Nancy, France
[2]INERIS, Verneuil, France

This paper presents preliminary estimations of CO2 overpressure into the reservoir and CO2 leakage through the caprock and the overburden. A simple, two-phase flow model in porous media based on Darcy’s law was used, in order to explore easily long time periods. The models produced by ... Read More

Estimation of Volcanic Deformation Source Parameters Through Optimization of Geodetic Data at Cotopaxi Volcano, Ecuador new

J. Hickey[1], J. Gottsmann[1], P. Mothes[2]
[1]University of Bristol, Bristol, UK
[2]Instituto Geofísico, Escuela Politécnica Nacional, Quito, Ecuador

Volcanic eruptions are often preceded by periods of unrest, where the behavior of the volcano deviates from a background level towards one of increasing concern [1]. Understanding what causes and contributes to unrest is a key challenge in volcanology today, influencing risk mitigation ... Read More

Integrating Geological Structures into 3D Numerical Groundwater Flow Models

S. Scheidler [1], B. Anders [1], H. Dresmann [1], P. Huggenberger [1],
[1] University of Basel, Department of Environmental Sciences, Applied and Environmental Geology (AUG), Basel, Switzerland

The 3D knowledge of complex geological systems and their integration into hydrogeological models is a prerequisite to study the dynamics of hydraulic processes at different scales. However, the integration of constructed 3D geological models (GOCAD©) into numerical groundwater flow ... Read More

An Extension of Lauwerier’s Solution for Heat Flow in Saturated Porous Media

S. Saeid[1] and F.B.J. Barends[2]
[1]Technical University of Delft, Delft, The Netherlands
[2]Deltares and TU-Delft, Delft, The Netherlands

One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and ... Read More

A 3D Thermal Model for Lunar Surface Using COMSOL Multiphysics® Software: Validation and Results

K. Durga Prasad [1], S.V.S. Murty [1], V. K. Rai [1],
[1] Planetary Sciences Division, Physical Research Laboratory, Ahmedabad, Gujarat, India

A comprehensive three dimensional finite element thermal model has been developed using COMSOL Multiphysics® software to understand the thermo-physical behaviour of the uppermost regolith layer of the moon. The model can simulate variable layers, layer thickness and dimensions and can ... Read More

2-Dimensional Incompressible and Compressible Mantle Convection new

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 ... Read More

Permeability in Fragmented Materials and its Application to Underground Mining

S. Palma [1], R. Castro [1], A. Hekmat [1],
[1] Mining Engineering Department, Block Caving Laboratory, University of Chile, Santiago, Chile

The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. The block caving technique is based on the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of ... Read More
