Modeling tools for water resource management; An introductory theoretical course will be offered and will allow you to become familiar with the essential notions of modeling. TDS sessions will follow where students will manipulate two models on synthetic, real or pseudo-real cases. The first model - FEFLOW - is intended to describe flow and transport processes in porous media. The second model – LISEM – describes the processes of flow, transport and erosion on the soil surface.
Advanced geographic information systems (GIS); The objective of the EU is to acquire in project mode the skills and know-how to diagnose an environmental problem using GIS functionalities. More specifically, this EU involves a project to diagnose the risk of runoff at the scale of agricultural watersheds.
In pairs, students will have to propose and carry out a diagnosis method from A to Z in the ArcGIS environment during several supervised sessions to optimize the design and implementation of the steps under GIS.
Field methods in hydrogeophysics; This course aims to present field methods useful in the field of hydrogeology. It consists of two parts: field methods in hydrogeophysics and hydrology
(1) In the section concerning hydrogeophysical aspects, students will discover how certain geophysical methods are particularly suitable for providing relevant information on hydrosystems.
The course will be divided into a first theoretical part (4 hours) introducing hydrogeophysics and certain geophysical methods, in particular electrical resistivity tomography and magnetic resonance. In a second practical part (7 hours), these methods will be implemented on the SCERES experimental platform on the CNRS campus in Cronenbourg (Controlled Experimental Research Site for Water and Soil Rehabilitation, https://ites.unistra. fr/services-platforms/pole-experimental/sceres).
Measurements traditionally carried out in hydrology will also be carried out by the students. The idea will then be to combine the information obtained using hydrological and geophysical tools to characterize the water transfer properties of the SCERES. The evaluation of the module will be based on an analysis report of the measurements carried out and interpreted by the students.

(2) In this part we will put into practice the theoretical lessons of hydro geology: measurement of a piezometric level on site, setting up a test pumping, a tracing test, a measurement flow rate, interpretation of experimental data.
Modeling a hydrogeological site with Visual Modflow - The following points will be covered in this course:
General information on spatial modeling and getting started with the code: 2 hours
Presentation of the study area and the documents necessary for the construction of the conceptual model (geological map, piezometric maps, permeability maps, rainfall data, ETP): 3 hours
Construction of the conceptual model, digitization of data, first simulations: 3 hours
Simulations and tests of different hypotheses (wells, pollution, depollution): 2 hours
