Objectives

Provide students with a set of structural concepts in the understanding and study of the circulation of groundwater. Particular emphasis is given to methods for quantitative analysis of the movement of groundwater. At the same time, practical classes will be based on the presentation of more technical knowledge of nowadays state of the art.

Learning outcomes and competences

It is intended that the future engineer stay with the Basic Concepts of hydrogeology enabling it to exercise professional activities in this area.

Program

Introduction – the water cycle: infiltration, regional and global water balance, watershed and groudwater basin. Exercises: calculation of RAS hydrogeological balance, precipitation and evapotranspiration. Fundamental equations in groundwater hydraulics: Navier-Stokes continuity. Gradient operator, divergence and Laplacian. Water in porous medium. Laplace equation. Analytical integration of water circulation in a porous medium by fracture or cylindrical orifices. Exercise: determination of fracture discharge with pre-defined piezometric conditions. Darcy’s empirical law. Porosity, hydraulic conductivity. Aquifers, aquitards and aquicludes. Circulation in fissured medium. Measurement of hydraulic conductivity. Serial and parallel association. Exercises: Darcy’s law; Darcy’s law in serial and parallel systems. Unconfined and confined aquifers; notion of transmissivity, storage coefficient; Graphical representation of aquifers, streamlines and isopiestic lines. Examples. Deduction of unconfined aquifer equations; Dupuit hypothesis. Extrapolation to the linear case of confined aquifers. Advantages of linearity. Steady state.
