D2.5 Advanced Hydrology of Groundwater and Modelling

The aim of this course is to introduce the basic theory and computational methods and techniques for modeling subsurface flow and contaminant transport and to develop practical groundwater modelling skills, an understanding of the subsurface flow regimes, the way in which conceptual models of a groundwater system can be built, and how appropriate modelling software can be used to include field measurements and test and refine the understanding of complex problems. A sound introduction to MODFLOW and FEFLOW software packages and application to case studies will be included.

  1. Basic principles of groundwater simulation and modelling standards. Hydraulics and hydrology of groundwater, mathematical formulation of the problem. Simulation of groundwater, formulation of 2-D (with the horizontal flow assumption) and 3-D models.
  2. Contaminant transport in groundwater, mathematical formulation of the groundwater pollution problem. Transport simulation.
  3. Groundwater models, one-cell and multiple cell models. Numerical methods. Finite difference method, application of MODFLOW software. Finite element method, application of FEFLOW software.
  4. Complex groundwater problems: Surface water and groundwater interaction, integrated management, methods of solution, mathematical modeling. Sea-water intrusion of coastal aquifers, methods of solution, the Ghyben Herzberg approximation, the Strack method, mathematical modeling. Unsaturated flow and introduction in multiphase flow problems.
