Learning unit contents

A. How to use the many data represented on a geological map? (1) Short presentation of the different rock types and their spatial organization; (2) the geological map: use and examples; (3) the geological map on the field.
B. An introduction of the fundamentals of hydrogeology and groundwater are proposed in this course: - Introduction - Definitions: groundwater resources advantages and drawbacks, relative importance in the world, in Belgium, in Walloon region. - Hydrological cycle and water balance of a basin, groundwater reserves. - Confined, water table and perched aquifers: definitions and examples, importance of a clear geological understanding when defining hydrogeological conditions. - Hydrogeological parameters and groundwater flow equations: hydrostatic, porosities, hydraulic conductivity and Darcy's law, intrinsic permeability, generalisation, application, limitations, measurements on field, piezometric maps, application examples, transmissivity, steady state groundwater flow in saturated conditions, specific storage coefficient, transient flow in confined and water table aquifers.

Part 2 : groundwater

An introduction of the fundamentals of man-made pressures on the underground and more particularly of hydrogeology and groundwater are proposed in this course: - Main pressures on the underground, Introduction - Definitions: groundwater resources advantages and drawbacks, relative importance in the world, in Belgium, in Walloon region. - Hydrological cycle and water balance of a basin, groundwater reserves. - Confined, water table and perched aquifers: definitions and examples, importance of a clear geological understanding when defining hydrogeological conditions - Natural quality of groundwater and main sources of pollution. - Hydrogeological parameters and groundwater flow equations: hydrostatic, porosities, hydraulic conductivity and Darcy's law, intrinsic permeability, generalisation, application, limitations, measurements on field, piezometric maps, application examples, transmissivity, steady state groundwater flow in saturated conditions, specific storage coefficient.

Learning outcomes of the learning unit

To understand a geological map and to be able to extract the information useful for environment management.
At the end of the course, the student will have a good understanding and knowledge about groundwater aquifers. He will be able to:
- compute a hydrogeologic water budget; - understand and exploite theoretical and practical hydrogeological concepts; - interprete hydrogeological maps; - draw and interprete piezometric maps; - predict and detect local hydrogeological specificities of a study-site;
Exercices and practical courses are lead by a local (Arlon) assistant. It will help each student to develop his self-sufficient capacities on practical and real case studies. The not compulsory reading of reference books (in english) will allow additional documentation and understanding of scientific texts in this topic.

Prerequisite knowledge and skills

The course requires basic knowledges of hydraulics and mathematical and vectorial analysis.

Part 1 : geological map

None.

Part 2 : groundwater

The course requires a good knowledge of general geology, geological mapping and basic knowledges of hydraulics and mathematical and vectorial analysis

Planned learning activities and teaching methods

The course is composed of "ex-cathedra" lectures, fieldwork and directed exercises sessions. The exercises sessions are organised in direct relation with the topics covered by the theory lectures.

Assessment methods and criteria

Exam(s) in session

Any session

- In-person

written exam ( open-ended questions )


Additional information:

A written exam intergrating the two parts of the course is organised in January and in September sessions. The allocation of points is as follows: 40% geological maps; 60% aquifers.
With open questions, the evaluation is based mainly on understanding the concepts and processes, but it requires also memorisation. Indeed, a good knowledge and perfect command of the fundamentals are needed for preparing accurate and adequate answers.
