The aim of this course is to provide students with a practical, high-level perspective on the hydrological modeling of watersheds dominated by agricultural activities and subject to climate change. The UE is structured around 4 points of view:

1. Watershed hydrology and its place in the history of science,

2. Specific features of agricultural landscapes and implications for modelling ,

3. Changing scales,

4. Practice and criticism of hydrological modelling.

The UE will provide advanced knowledge of production functions, transfer functions, global and distributed modeling. Students will be able to work independently with various hydrological models (Green and Ampt, reservoir, Curve Number, unit hydrograph, reservoir cascade, etc.), and to step back from the parameterization, calibration and validation of hydrological models.

The status of a watercourse as defined by the WFD comprises two aspects: chemical and ecological. To define the ecological status, several parameters need to be taken into account, including those related to the volume of water (via flow measurement) in the watercourse. In this course, students will be required to carry out field or laboratory measurements to determine some of the key parameters used to determine the state of a watercourse or, more generally, those used in hydrological studies (flooding, resource assessment, etc.).

4 aspects will be covered:

- Hydrometry, using various gauging techniques (point-by-point method with electromagnetic current meter, ADCP, dilution method, float gauging, radar).

- Soil hydrodynamics, with the use of several infiltrometry methods to determine saturation conductivity, and the sampling of soil cylinders to determine soil porosity, dry density and water content after drying.

- Hydrochemistry, with :

• a field section (sampling and analysis with a multiparameter and a field spectrophotometer) for physico-chemical parameters (temperature, electrical conductivity, pH, dissolved oxygen, TAC, PO4 and NO3, etc.)
• a laboratory part (analysis and quantification of 4-tert-octlyphenol in a surface water sample, using gas chromatography coupled with mass spectrometry (GC-MS/MS)) to determine the trace presence of emerging contaminants from the alkylphenol ethoxylate (APEO) family, compounds found in products such as detergents, emulsifiers and solubilizers.

- Hydrobiology, which takes into account the presence or absence of certain species: fish, invertebrates, macrophytes (aquatic plants) and diatoms (unicellular algae), with a view to determining specific indices (IPR, IBGN, IBMR, IBD) relating to the biological quality of the watercourse.

This course focuses on natural mineral waters and thermal waters, whose specific characteristics make them special resources in terms of exploitation, management and protection of their deposits. Students will be trained in the specific technical and regulatory/health aspects of exploiting these resources, notably through presentations by industry professionals and a visit to an exploitation site. They will also be made aware of the management and protection of this type of aquifer, so as to be able to propose study protocols to be implemented in situ to characterize and protect these resources, and thus acquire hydrogeological expertise for this type of aquifer.

This course is designed to enable students to acquire the skills needed to collect hydrometric data (in the broadest sense) in the field and apply them to different types of case study, in order to carry out an engineering/research project in hydrogeology.

This UE is divided into two parts:

• A first week entirely in the field in the Pyrénées Orientales department;
• A second week was spent in the classroom, processing, analyzing and interpreting the data acquired in the field.

During the^1st week, the first 3 days are devoted to acquiring the various technical skills in hydrometry (in the broadest sense) in situ, so that the students can then become "project managers" during the last 2 days, when they will work on a case study to be solved by project groups. They will then be assigned to 2 experimental sites, where the projects to be carried out will be defined. The subjects will be presented in greater detail at the beginning of the course, so that the groups can propose an experimental protocol to be carried out in situ, enabling them to solve their problem. The supervisory team will validate the proposed protocols the day before the experiments begin.

During the^2nd week, the students will go through the data acquired on their field-project, and will share out the various analyses and interpretations of this data in order to propose a presentation and a report integrating and synthesizing all these results, which will serve to evaluate their work.

This course is divided into a theoretical part, which provides an understanding of groundwater transfer, and a more practical part, which combines field work, numerical modeling and environmental studies. Quantitative hydrogeology is approached through analytical and numerical solutions to account for transfers in the underground environment.

This UE covers in particular:

1) mathematical tools and fundamental equations underlying analytical and numerical modelling;

2) the principles of numerical modeling ; 

3) a typical methodology for creating a 3D numerical model for flow simulation and ;

4) analysis of scenarios integrating climatic and anthropogenic forcings for optimal management of water resources.

The "hydrological/hydraulic modeling and flood risk" module covers the study of flood genesis, flood propagation and flooding. The module aims to enable students to acquire skills in hydrological and hydraulic modeling of processes at watershed and river scales:

1) The production function, which separates rainfall into runoff and infiltration;

2) The transfer function on slopes and via the hydrographic network, overflow and flooding;

3) Construction of a project rainfall and synthetic hydrograph;

4) Applications of hydrological and hydraulic flood models.

The course also includes a field day (in situ data acquisition for hydrological/hydraulic modeling purposes, in situ flood risk analysis).

The tutorials focus on practical applications in watersheds and rivers in France and abroad, using spatialized hydrological flood models (e.g. ATHYS, MHYDAS) and hydraulic models (HEC-RAS, Onde diffusante, Onde cinématique, etc.).): analysis of rainfall/discharge data, use of hydrological/hydraulic models, parameterization/calibration/validation of models, analysis of the impact of development scenarios (dike, dam, etc.).

This course covers the concepts of mass and heat transfer in aquifers, as well as the characteristics of low- to high-energy geothermal energy.                                                                                                                                                                                                             

The vulnerability of the underground resource will be assessed and, where appropriate, methods for protecting the aquifer from pollution will be evaluated. Various techniques for cleaning up aquifers will also be discussed, with particular emphasis on the answers offered by numerical simulation tools.

The principles of geothermal energy will also be discussed, with examples of specific systems based on the three types of geothermal energy (from shallow to very deep, from low temperature to very high temperature).

This course is based on the Vidourle Mediterranean watershed and the new experimental site of the Observatoire Multi-Échelle de la DYnamique des Crues et de l'hYdrodynamique Souterraine en milieu karStiques (MEDYCYSS - OSU OREME -SNO KARST). 

A first day in the field introduces the geographical, geological and climatic context, as well as the various geomorphological elements, the different orogenetic phases and their links with vegetation. A stop at the experimental site introduces the measuring devices used (rain gauge, flow tower, probes measuring soil temperature and humidity, etc.), before tackling the issue of hydrological risk with the Conqueyrac flood control dam. A more theoretical section redefines the concepts of geomorphology and hydrogeomorphology, and looks at soil-vegetation-atmosphere transfers.                            

The second day in the field, around the experimental site located near the causse de Pompignan, is devoted to field measurements: infiltration into the soil to determine hydraulic conductivity at saturation, sampling of soil cylinders to determine porosity, water content and density, vegetation measurements, flow measurements.   

The last part of the course is devoted to hydrological modeling, with an introduction to the HEC-HMS software through practical exercises, aimed at estimating available water resources on a BV scale (including evapotranspiration), and forecasting flows during floods, particularly during Cevennes episodes. Data measured in the field will be fed back into this modeling work.

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 present the current and future impacts on all sectors associated with the water sector.

What are the trends in climate extremes such as droughts and floods, and in the regions affected by these extremes? What impact will this have on underground and surface water resources, agricultural land and irrigation methods?

How are sea levels and coastlines changing? How does this impact current and future population movements, and what solutions can be proposed for coastal management?

Through a series of lectures given by specialists from different fields, and covering all the Water Master's courses, this course will present the latest advances in this field.

Through TD and TP sessions, students will be asked to work in groups on a particular theme (using an example) associating climate change with a water-related field, in order to present a summary of the subject. This work will be presented in the form of a mini-seminar, and will be assessed as part of this course.

Water resources and their management are often approached through the knowledge and principles established in the developed countries of the temperate zone. Yet the countries of the South, starting with the Mediterranean and Africa, offer us an extreme diversity of social and environmental situations that force us to significantly modify our points of view and question the validity of certain approaches that are too far removed from the reality on the ground.

Researchers working mainly in developing countries draw on their practical experience to reflect on the specific nature of hydrological and geochemical processes in very dry or very wet tropical regions, the consequences of anthropization and the challenges of sustainable water resource management.

A significant amount of time is devoted to critical analysis of scientific articles dealing with water resources and their management in the South.
