The aim of the Course is oriented to help a future professional in the interpretation of the water-rock interactions between aqueous solutions stored in a geological reservoir. Having the global water cycle in mind an environmental technician should understand at glance what is happening in an aquifer by means of water sampling, graphical interpretation of diagrams and processing of water analyses. This is done in the first part of the Course.
The second part is devoted to show a series of tools useful to prepare the numerical modeling of a reactive transport simulation by finite difference method showing how some numerical techniques (i.e. Newton-Raphson method for system of linear equations) enable the solution of 3D models built by field geological informations.
Changing observation scale, both in space and in time, some finer features of the inter- and intra-aquifer dynamics with other compartments of hydrosphere will be enlightened by the use of the imprinting of stable isotopes of hydrogen and oxygen. The meaning of the isotopic fractionation factor will be presented here.
The Course ends with the presentation of techniques of aqueous solution speciation calculations in thermo-baric condition characteristic of shallow groundwaters throwing the intimate relations between water and mineralogical nature of of the geological aquifer system.
Some practical water sampling and data measurement issues will be shown directly in the field. The theory presented in the Course will be coupled with computational practice helping the students to how convert an idea, based on (hydro)geological field experiences, to a useful model expanding the geochemical knowledge of systems.
