Skills and Tools

Areas of expertise

During our interventions, we address the following areas:

• General hydrology
  • water cycle and basic processes
  • catchment areas and measures
  • water balance and water regime
• Hydrological modelling
  • main principles
  • rain-flow model shimming
  • model validation and application
  • hydrological simulation on lightly or ungauged basins
  • uncertainty quantification
• Applied hydrology
  • statistical analysis of hydrological data
  • flow predetermination
  • regionalization approaches
  • water risk and resource management
  • spatial variability and flow mapping
• Flow forecasting
  • flood and low-flow forecasting
  • hydrometeorological forecast chain
  • ensemble forecasting and uncertainties
  • assessment of the quality and value of forecasts
• Impact of global changes
  • climate change impacts
  • impact of land use change
  • coping strategies
• Computer programming
  • beginner’s level
  • advanced stage
• Introduction to hydrology
  • speeches for the general public

Tools offered

For the teaching of hydrological modelling, the team offers tools for educational purposes.

Open Source Software

• Excel Spreadsheets:
  • GR4J hydrological model
  • CemaNeige snow accumulation and melting model
• airGRteaching
  • R package: very simple functions to use all the GR models (including GR4J and GR2M + CemaNeige) and a graphical interface
  • Online Graphical User Interface: to avoid computer programming (GR4J, GR5J, GR6J + CemaNeige)

Role-playing games

The team has also developed several role-playing games to address issues related to hydrological forecasting, available for download at HEPEX.
