Hydrogeology

This course introduces groundwater in the hydrological cycle and discusses the properties of the water/rock complex: porosity, permeability. It provides the essential notions of groundwater hydrodynamics in natural and artificial flow and elementary hydrochemistry of groundwater.

The acquisition of knowledge is facilitated by the practical application of the course during practical sessions on a column (measurement of porosity and permeability, establishment of Darcy's law, tracing with salt) and in class (resolution of common hydrogeological problems based on the reading of piezometric and hydrogeological maps - construction and interpretation of piezometric maps - interpretation of well and water table tests - meaning of physico-chemical analyses of water)

A field day illustrates the relationships between geological structure and hydrodynamic functioning and provides an introduction to drilling measurement techniques.

Hourly volumes:

• CM : 13h
• TD :14h
• Practical work: 12 hours
• Field :6h

The objective of this course is to acquire both theoretical and practical skills in hydrogeology in order to be able to pursue a master's degree and also to be directly operational in the professional world.

Students will understand the relationship between geological structure and hydrodynamic functioning of aquifers in order to understand and interpret fundamental hydrogeological processes and to be able to assess their impact on groundwater management and protection

Geological mapping

100% Full Continuous Testing:

• 4 grades - 50% (PT+Field+CC1)
• +50% CC2

Know how to solve common hydrogeology problems based on reading piezometric and hydrogeological maps and using data. In this context, the student must know:

• Identify aquifers from a drilling log or geological section
• Master the techniques of reading and analyzing a hydrogeological map to deduce the functioning of a groundwater table
• Master the techniques of construction and interpretation of piezometric maps (Theory and practice)
• Calculate a gradient and a flow from data or piezometric curves
• Interpreting a well and water table test
• Relate a physico-chemical analysis of water to a type of rock
