Bescherming van Noordzeekanaal tunnels tegen scheepvaart calamiteiten: Casus Velsertunnels

Het Noordzeekanaal verbindt de Haven van Amsterdam met de Noordzee via het sluizencomplex van IJmuiden. In de huidige situatie is de Noordersluis maatgevend voor de maximale diepgang van de scheepvaart op het Noordzeekanaal. Met de geplande realisatie van Zeesluis IJmuiden begin 2022, zal de Noordersluis niet langer maatgevend zijn voor de...

Shear Capacity of Large Structural Elements: A case study of the shear behavior of the itaipu concrete lock walls

The concept of shear loading and the shear resistance is well known for ‘regular’ sized beams, meaning beams that can be characterized as a slender beam. However, once the beam increases in size such that it is characterized as a deep beam or even falls outside the range of the typical deep beam, less knowledge is available....

Ship collision on inflatable weirs: Case study: weirs in the Meuse

In the Meuse seven weirs are located in the Dutch reaches, controlling the water level to enable inland navigation through the river. The weirs are being scheduled for replacement, where weir Grave is the first one in 2028. They are reaching their end-of-life time. One of the main issues that became of more importance in the recent years is ship...

Gate Driving Mechanisms and Dynamics

Vertical sliding valves that are part of a filling and emptying system of a lock are often subjected to an underflow of water during emptying and filling. The flow induces time varying forces on the structure which leads to dynamic behaviour of the valve. Whether the structure is in the range of resonance and what the amplitude of the vibrations...

Smoothed Particle Hydrodynamic Modelling of Wave Impact: A numerical and theoretical analysis of non-breaking wave loads on structures with overhang

Hydraulic structures can be prone to impulsive wave impact, which is a highly stochastic and uncertain process. This type of impact, defined by extreme pressure peaks and a very short duration, is not only caused by breaking waves, but also by non-breaking standing waves on structures with an overhang, such as culverts and steel gates. In this...

Techno-economic feasibility of Hydropower at weir-complex Driel with assessment method for low-head run-of-river powerplants

The goal of this research is to assess technical and economic feasibility of hydropower at the weir-complex of Driel. A local initiative opting to improve the environment gained interest in the idea and asked Arcadis NL for help. The weir complex at Driel lays in a key position in the Dutch river Delta and regulates the flow to the IJssel and...

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...

Flow-Induced Vibrations of Fibre-Reinforced Polymer Hydraulic Gates

Hydraulic structures that are surrounded by flowing water can experience undesirable Flow-Induced Vibrations. These vibrations have a record of negative consequences. The most important cause of vibrations is self-excitation. This is a mechanism in which the forces acting on the hydraulic gate are amplified by the movement of the hydraulic gate...
