Syllabus
Learning Objectives
To conceive soils and rocks as porous media governed by Solid and Fluid Mechanics. To formulate and implement Finite Element and Finite Differences numerical models with the objective to analyze the processes that govern ground response, to interpret field information and to predict soil response. To analyze, discriminate and integrate geological and geotechnical information in studies and projects. To calculate, evaluate, plan and regulate surface and groundwater resources.(Specific competence of the specialization in Groundwater Hydrology). To assess and manage environmental impacts from waste disposal, soil contamination and groundwater pollution. (Specific competence of the specialization in Groundwater Hydrology). To design and execute hydraulic systems, including transportation facilities, distribution and storage of solids, liquids and gases, water treatment plants and waste management (urban, industrial or hazardous). (Specific competence of the specialization in Groundwater Hydrology). To assess and manage projects, plants and water facilities for the environmental point of view. (Specific competence of the specialization in Groundwater Hydrology). To model, assess and manage geological resources, including mineral and thermal groundwater. (Specific competence of the specialization in Groundwater Hydrology). * To know the main basic principles of multiphase contaminants flow and transportation in saturated and unsaturated areas of the subsoil. * To understand the behaviour and transportation mechanisms of organic contaminants in non aqueous liquid phase and showing scarce solubility in water. * To known the remediation outline for soils and aquifers and to be able to mathematically model them. * To be able to carry on a study on the potential impact of a soil or water contamination problem on the population or the ecosystems. * To understand the thermodynamic processes and their effect on the chemical signature of water. * To know and model the main mass balance transfer processes. * To understand the importance of chemical kinetics and existence of advanced geochemical models. * To solve simple geochemical problems. - Thermodynamics: internal energy, entropy, enthalpy, Gibbs free energy . - Thermodynamic properties of pure substances.

Teaching Methodology
El curso se divide en sesiones teóricas y problemas, donde se prevee el uso de programas convencionales de cálculo geoquímico. Although most of the sessions will be given in the language indicated, sessions supported by other occasional guest experts may be held in other languages.
Grading Rules
The evaluation calendar and grading rules will be approved before the start of the course.
The course is evaluated through exercises and a final assignment.
Test Rules
Failure to perform a laboratory or continuous assessment activity in the scheduled period will result in a mark of zero in that activity.
