Reducing Water Level Prediction Uncertainty in a Delfland Polder using Data Assimilation

Polder areas as typical in the Netherlands require real time control on the water levels. Efficient pumping is a subject with increasing interest due to a required use of 20% green energy by 2020 set by the government. In 2010, the energy requirements already exceeded 175 GWh per year. For optimal control, water level predictions are important....

Value of information on the operation of a dual-purpose reservoir

Reservoirs are often operated to meet two or more objectives that sometimes may conflict. An example of this conflict is to keep storage low enough to maintain spare capacity for flood protection, but also to keep it high enough to maintain reliability of water / hydropower supply. Optimising the control decisions of reservoirs can provide a...

On-line parameter updating as an optimisation tool for Decision Support Systems

Decision Support Systems (DSSs) that are used nowadays by water managers often predict states that do not correspond with the observed states. This is caused by changing parameters in the real systems, while the parameters used in the current DSSs are kept at a fixed level or follow a temporal pattern that does not always represents reality....
