General hydrology [ LBIRE2103 ]

- Issues of water management at the local and catchment scale - Hydrological cycle (rainfall, infiltration, run-off, drainage, hypodermic flow, evapotranspiration) : processes, mathematical description, measurement methods and interpretation. - Hydrological modelling at the field and catchment scale - Hydraulic control of surface water flow

At the end of the theoretical course (2.5 ECTS) and the practical exercises (2.5 ECTS), the students must be able : - to understand the issue of water management at the scale of the local scale (the field parcel) and the scale of the catchment ; - to describe the different processes and the different terms of the hydrological cycle at the scale of a pedon, the field parcel and the catchment, and to understand the equations used for describing these processes ; - to describe the functioning, the advantages and disadvantages of hydrological measurement devices ; - to interpret basic hydrological measurements (rainfall, evapotranspiration, drainage and run-off); - to calculate, by means of simple hydrological models, the rainfall runoff relationship at the field and catchment scale; - to justify the choice of a hydraulic device to control the surface water flow at the field and catchment scale; and - to write a synthetic report on the practical work and to analyse critically the obtained results.

Theoretical courses - Introduction. Issues of hydrology at different scales - Rain- Infiltration - Evapotranspiration - Run-off - Hydrological modelling - Hydrological control Practical work The theoretical aspects are illustrated by means of practical work in the laboratory and computer class room around 2 hydrological projects : the design of a storm bassin in a catchment and the calculation of the hydrological balance of a field parcel. An excursion allows to illustrate concepts of hydrometry and hydrological control.
