Description
These karstic hydrosystems represent an important proportion of the groundwater supplying the population in France, but also on the whole Mediterranean rim. They also play an important role in the so-called Cevennes floods (or existing on the Mediterranean rim), especially in their management. These hydrosystems are also characterized by important interactions between surface water and groundwater: either active losses located in rivers, which directly feed the associated karstic aquifer, or major karstic springs at the origin of rivers or streams. A presentation of these hydrosystems and their functioning, of their study method, will be realized within this UE. The aspect " Surface water - Groundwater interaction " will be particularly treated in this UE, through the study :
- Artificial tracings: Techniques, Methods of realization (theoretical and practical), Methods of analysis and interpretation. Artificial tracing
- Signal processing and rainfall-flow modeling, especially of karst springs that are the source of rivers.
These teachings will take place in the form of theoretical courses, but also of practical work with the processing of artificial tracing data or the processing of spring flow signals. A day field trip will allow to realize various experiments on a karstic hydrosystem, in particular an artificial tracing.
Objectives
The objective of this course is to master the tools of artificial tracing and signal processing, through the study of karst hydrosystems which play a major role in the study of groundwater and surface water resources, particularly in France and the Mediterranean region.
Necessary pre-requisites
To have acquired the bases in hydrogeology and hydrology of the M1 Water Resource (to have validated UEs equivalent to Water Cycle, Functioning of Hydrosystems, Hydrodynamics of the M1)
Knowledge control
The control of knowledge includes a note of TP (continuous control in the form of report or presentation of work carried out in TP), and a note of final control relating to the theoretical knowledge approached in the UE.
