RISK-BASED DECISIONS
When water levels are high, decisions are continuously being made on the basis of uncertain information. This project develops methods that link this information about the system to the equally uncertain added value of interventions. In this way, a mathematical decision model is being developed that makes the uncertainty in the available information explicit. Conditional failure probabilities are the decision-making criterion here.
The knowledge and methods will be optimised, tested and validated in a ‘dashboard’ that is under development. This FC2015 Dashboard Water Safety provides users with an up-to-date picture of water safety. They can use the resource in operational situations, but also opt to install certain 'meters' in their own existing systems. Testing and validation take place in, among other locations, Indonesia and Thailand.
As with a car, the dashboard displays a number of indicators and reports when one or more threshold values are exceeded. And, as with mechanics who can understand more by looking at the logbook than the driver of a car, users will soon be able to decide themselves how they want the information about, and forecasts for, water levels, water defences, floods and interventions to be displayed.
Sub-projects:
- Solution methods for decision-making models [numerical decision-making model]
- Optimal management during high-water alarm conditions [optimisation of the management of large-scale hydraulic infrastructure in the Rhine/Meuse delta when water levels are high]
- Evacuation strategies
- Dashboard
- Trial projects in Jakarta and Ho Chi Minh
- Integration of high-water predictions and alarm levels
