The EU aims to accompany students to the practice and the high level of hindsight on the hydrological modeling of watersheds dominated by agricultural activities and subject to climate change. The UE is articulated around 4 points of view:
1. Watershed hydrology and its place in the history of science,
2. Specificities of agricultural landscapes and implications for modeling ,
3. The problem of changing scales,
4. Practice and critique of hydrological modeling.
The course will provide advanced knowledge on production functions, transfer functions, global and distributed modeling. It will lead the students to the autonomous practice of different hydrological models (Green and Ampt, reservoir, Curve Number, unit hydrograph, cascade of reservoirs, etc.) and to step back on the parameterization, calibration and validation of hydrological models.

The status of a river according to the WFD includes two aspects: a chemical status and an ecological status. To define the ecological status, several parameters will have to be taken into account, including parameters related to the volume of water (via flow measurement) of the watercourse. In this course, students will be asked to carry out field or laboratory measurements to determine some of the key parameters in the determination of the state of a river or more generally used in hydrological studies (floods, evaluation of the resource...).
4 components will be addressed:
- Hydrometry, with the use of different 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 the saturation conductivity, the sampling of soil cylinders for determination after drying of the porosity, dry density, and water content of the soil.
- the Hydrochemistry component, with :
- a part on the field (sampling and analysis with a multiparameter and a field spectrophotometer) for physico-chemical parameters (temperature, electrical conductivity, pH, dissolved oxygen, TAC, PO4 and NO3, ...)
- a part in laboratory (analysis and quantification of the presence of 4-tert-octlyphenol in a surface water sample, by gas chromatography coupled to mass spectrometry (GC-MS/MS)) to determine the presence of emerging contaminants of the alkylphenol ethoxylate (APEO) family, compounds present in products such as detergents, emulsifiers and solubilizers.
- the Hydrobiology component, with the presence or absence of certain species taken into account: fish, invertebrates, macrophytes (aquatic plants) and diatoms (unicellular algae), in order to determine specific indices (RPI, NBI, RMI, DBI) relating to the biological quality of the watercourse.
