Karst hydrology - Signal processing

These karstic hydrosystems account for a significant proportion of the groundwater used to supply the population of France and the entire Mediterranean region. They also play an important role in the management of floods known as Cévennes (or existing around the Mediterranean). These hydrosystems are also characterized by significant interactions between surface water and groundwater, whether through active losses in rivers, which feed directly into the associated karstic aquifer, or through major karstic springs, which are at the origin of rivers. A presentation of these hydrosystems and how they function, as well as the methods used to study them, will be included in this course. The "Surface water-groundwater interaction" aspect will be particularly covered in this course, through the study of :

• Artificial tracings: Techniques, Methods of realization (theoretical and practical), Methods of analysis and interpretation. Artificial tracing
• Signal processing and rainfall-runoff modeling, in particular for karstic springs that create rivers.

These lessons will take the form of theoretical classes, as well as hands-on exercises involving the processing of artificial tracing data and spring flow signal processing. A day-long field trip will enable us to carry out various experiments on a karstic hydrosystem, in particular artificial tracing.

The aim of this course is to master the tools of artificial tracing and signal processing, through the study of karstic hydrosystems, which play a major role in the study of underground and surface water resources, particularly in France and around the Mediterranean.

To have acquired a basic knowledge of hydrogeology and hydrology from the M1 Eau Ressource (to have validated the equivalent UEs in Water Cycle, Functioning of Hydrosystems, Hydrodynamics from the M1).

The assessment of knowledge includes a grade for practical work (continuous assessment in the form of a report or presentation of work carried out in practical work), and a grade for a final test based on the theoretical knowledge covered in the UE.
