Optimising reinforcements in flood defence systems with multiple lines of defence

Under growing pressures of climate change, it is vital for our society to implement cost-effective reinforcements in a flood defence system. This thesis proposes a method for optimising reinforcements in a flood defence system with multiple lines of defence under sea level rise.

Assessment of a storm surge barrier: A probabilistic fragility-based framework for the assessment of complex hydraulic structures

This thesis introduces a fragility-based framework in order to perform a custom assessment of the complex Eastern Scheldt storm surge barrier. By applying a conditional approach to loading parameters, the statistical dependency between failure mechanisms and structure elements can be described separately for the strength and loading part of the...

Impact of Tidal Energy Extraction in the Eastern Scheldt Storm Surge Barrier on Basin Hydrodynamics and Morphology

The Eastern Scheldt basin is protected by a semi-open storm surge barrier that was completed in 1986. In 2015 a set of five turbines was installed in one of the barrier openings as a pilot for tidal energy extraction. Due to the construction of the barrier, the average tidal range and velocities have significantly decreased throughout the basin...

Physical Scaling of Tocardo’s Eastern Scheldt Turbines: Additional Graduation Work

Additional thesis - The largest structure of the Dutch Delta Works, that protect the Netherlands against high water levels at sea, is the Eastern Scheldt storm surge barrier. The Eastern Scheldt barrier is constructed as an<br/>open structure that can separate the Eastern Scheldt estuary from the North Sea. In case that water<br/>levels of +3.00...

A future proof Eastern Scheldt storm surge barrier

The worst flood of the 20th century happened at the night of January 31, 1953. After this disastrous flood the Dutch government came up with The Deltaworks, a large scale plan to protect the hinterland against future threats of high water. As part of the Deltaworks the Eastern Scheldt area was compartmentalized with the Eastern Scheldt storm...

Pressures in Sand from Waves and Caisson Motion

In The Netherlands recurring floods have occurred in the southwestern part of the country from infrequent large storm surge from the ocean. The Delta plan was originated to increase the safety against flooding. This resulted in shortening of the coastline by closure of various estuaries, including the Eastern Scheldt estuary. A closure of the...
