Simulation of Poyang Lake water levels and outflow under historical extreme hydrological scenarios

Due to an intensification of anthropogenic activities and climate change in recent decades, the hydrological connections and relationships between rivers and lakes have been significantly modified globally. Poyang Lake is one of the largest freshwater lakes globally and is one of the few that remain naturally connected to the Yangtze River....

A Kalman filter approach to realize the lowest astronomical tide surface

In this paper, we present a novel Kalman filter approach to combine a hydrodynamic model-derived lowest astronomical tide (LAT) surface with tide gauge record-derived LAT values. In the approach, tidal water levels are assimilated into the model. As such, the combination is guided by the model physics. When validating the obtained “Kalman...

A knowledge intervention to explore stakeholders’ understanding of a dynamic coastal nature reserve

As quantitative modelling can be used to build stakeholder understanding for management decisions, and can help build consensus (Stave, 2003), a system dynamics modelling study of the abiotic dynamics of an archetypical small estuary, the Slufter in the Netherlands is formulated. The model is used in combination with an analysis of stakeholders’...

Roadmap to a mutually consistent set of offshore vertical reference frames

This thesis presents a combined approach for the realization of the (quasi-)geoid as a height reference surface and the vertical reference surface at sea (chart datum). This approach, specifically designed for shallow seas and coastal waters, provides the relation between the two vertical reference surfaces without gaps down to the coast. It...

Real-time Control of Combined Water Quantity & Quality in Open Channels

Fresh water supply and flood protection are two central issues in water management. Society needs more and more fresh water and a safe water system to guarantee a better life. A more severe climate will result in more droughts and extreme storms. As a consequence, salt water intrusion will increase. Therefore, clean and fresh water is becoming...

Rainfall fed inundation in greenhouse dominated polders: Research of water system assessments

Since the end of the last century, polders in the Netherlands have suffered from inundation due to heavy rainfall. Inundation occurrences in 1998 have led to large economic losses, especially in polders with a fast rainfall runoff process due to the high percentage of land occupied by greenhouses. This thesis focuses on water system assessments,...
