Probabilistic approach for flood safety
Flooding is a severe problem worldwide. The Netherlands is well known on its expertise in managing the water and flood prevention. Due to the recently developed EU Flood Directive, The Netherlands developed new projects in order to determine the flood risks for every area in the country. The projects FLORIS (VNK) and WV21 are the first projects that develop and apply flood risks methods in the Netherlands. The project FLORIS aims to give an actual and realistic estimation of the flood risk for all dike ring areas. The WV21 project calculates flood risks in order to achieve information on new safety level standards.
This course is based on the approach used in the project FLORIS. The participants learns the background of the probabilistic approach and the basic principles of using existing data and modelling. The set-up of a river system and an flood prone area in a model, the modelling itself and the results interpretation is part of the course. Based on the modelling results, the damage of flooding (economic and casualties) is handled. Finally the participants learn how to present the flood hazard and flood risk in maps.
The course exists of the following topics:
- Flood risk management (The Netherlands & EU Flood directive)
- Probabilistic flood risk approach
- Modelling principles (how to build and to use a model?)
- Software packages for modelling
- Data collection and gaps in data
- Damage determination and calculation
- Mapping principles
- Flood hazard map
- Flood risk mapping
Hand-outs of the presentations, exercises and background information.
The participants have to use computers during the training. The software package in which the participants normally model (like SOBEK or MIKE) could be used in the course.
The participants can work on chosen study areas as practical exercises during the training.
