Content and teaching methods
- Precipitation : precipitation mechanism : condensation, hydro-meteorological context, types of rains ;
rainfall data : rain measurement, duration-intensity-frequency curves, extension to a watershed ;
- Hydrologic budget : hydrologic cycle, evaporation, infiltration ;
- Streamflow : streamflow data and measurement, cumulative discharge curve, flow-duration curve : characteristic elements, parabola of Coutagne, shifted lognormal law of Galton-Gibrat, applications to navigable rivers and hydroelectric production ;
- Hydrographs : factors influencing the hydrograph shape, separation between base flow and net hydrograph ;
- Rainfall-discharge relation and hydrograph construction : unit hydrograph, rational method, application to urban drainage (Hauff-Vicari method).
Statistical hydrology (3 hours) :
- Floods: definition and characterisation ;
- Extreme values probabilistic and statistical models :
- Average and maximum rainfalls : the exponential distributions, maximum annual flow : the lognormal distribution (method of moments and method of maximum likelihood).
