Aims
Main themes
Content and teaching methods
* Causes for flooding
* Worsening factors
* Flood risk management
- Forecasting of high and low water levels :
* Empirical methods : method based on time series, catchment-based methods
* Statistical methods : reminders
* Determination of flood discharges based on extreme rainfall data : 'Gradex' method
- Discharge regulation :
* Reservoir management : Damping of peaks and flood routing, Simulation of exploitation : Cumulative discharge curve, stochastic modelling (lognormal model, seasonal autoregression model of Fiering), Reservoir sedimentation : critical silting discharge, evolution of sediments charac-teristics, sedimentation modelling
* Mitigation of floods induced by hydropower
- Flood protection :
* Catchment management
* Embankments
* Floodplains management
- Flood propagation
* Flood routing (Muskingum method)
* Flood modelling (Flood cells method)
- Droughts and low water levels
* Framework : origin and worsening factors
* Prediction of low water levels
* Analysis of dry seasons and droughts
