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...

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...

Linking water and energy objectives in lowland areas through the application of model predictive control

Unlike mountainous areas, lowland areas have limited potential to generate energy from water flows. Instead, for water systems in lowland areas that continuously need to pump water out of the system, the focus should be set to saving energy in the present water management. This paper gives an introduction into possibilities to manage water...

Clustered K nearest neighbor algorithm for daily inflow forecasting

Instance based learning (IBL) algorithms are a common choice among data driven algorithms for inflow forecasting. They are based on the similarity principle and prediction is made by the finite number of similar neighbors. In this sense, the similarity of a query instance is estimated according to the closeness of its feature vector with those...

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...

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...

The Effect of Four New Floodgates on the Flood Frequency in the Dutch Lower Rhine Delta

The Dutch Lower Rhine Delta, a transitional area between the Rivers Rhine, Meuse and the North Sea, is at risk of flooding induced by infrequent events of storm surges or fluvial floods, or the combination of both. To protect the delta from storm surges, it can be closed off from the sea by large dams and controllable storm surge barriers. Also,...

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...

Model Prediction Control For Water Management Using Adaptive Prediction Accuracy

In the field of operational water management, Model Predictive Control (MPC) has gained popularity owing to its versatility and flexibility. The MPC controller, which takes predictions, time delay and uncertainties into account, can be designed for multi-objective management problems and for large-scale systems. Nonetheless, a critical obstacle,...

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...
