Influence of load interdependencies of flood defences on probabilities and risks at the Bovenrijn/IJssel area, The Netherlands

In the Netherlands, flood risk analysis is usually carried out for a location, without considering potential flood defence failures in upstream areas. This may result in significant over- or underestimation of flood risks. The effect of upstream failures on failure probabilities and flood risks in other areas is called load interdependence of...

Kantelstuwmeting op basis van beeldherkenning

Een nieuwe manier van meten van kantelstuwstanden, de Mobile Tracker-­FL, wordt momenteel getest bij het hoogheemraadschap De Stichtse Rijnlanden. Waterschap Aa en Maas, heeft de meetmethode, na een uitgebreide pilot, in gebruik genomen. De methode werkt met een klein, speciaal waterpas, dat op de stuw gemonteerd wordt. Met een smartphone-­?app...

A joint probability approach using a 1-D hydrodynamic model for estimating high water level frequencies in the Lower Rhine Delta

The Lower Rhine Delta, a transitional area between the River Rhine and Meuse and the North Sea, is at risk of flooding induced by infrequent events of a storm surge or upstream flooding, or by more infrequent events of a combination of both. A joint probability analysis of the astronomical tide, the wind induced storm surge, the Rhine flow and...

Influence of a storm surge barrier’s operation on the flood frequency in the Rhine Delta area

The Rhine River Delta is crucial to the Dutch economy. The Maeslant barrier was built in 1997 to protect the Rhine estuary, with the city and port of Rotterdam, from storm surges. This research takes a simple approach to quantify the influence of the Maeslant storm surge barrier on design water levels behind the barrier. The dikes in the area...

Distributed model predictive control for multi-objective water system management

Model selection for salt water intrusion in delta areas

Due to land subsidence and sea level rise, salt intrusion in delta areas increases. This is a potential thread for agriculture in these areas. To investigate this thread and measures that can counteract on it, numerical models are developed to mimic the behavior of the water system under different strategies and scenarios. This behavior is...

Coordinated model predictive reach control for irrigation canals

Irrigation canals are large-scale systems, covering vast geographical areas, and consisting of many interconnected canal reaches that interact with control structures such as pumps and gates. The control of such irrigation canals is usually done in a manual way, in which a human operator travels along the irrigation canal to adjust the settings...

Model predictive control on open water systems

Human life depends on water daily, especially for drinking and food production. Also, human life needs to be protected against excess of water caused by heavy precipitation and floods. People have formed water management organizations to guarantee these necessities of life for communities. These organizations manage a water system within the...
