Unravelling Drivers of Morphological Change: A Case Study on the Prins Hendrik Sand Dike

Berning, Max (author)

Flood defense will have to be strengthened all over the world as sea level rise poses great challenges for the safety of coastal settlements. Strengthening traditional hard flood defenses is becoming increasingly more difficult due to limited space in the coastal zone and large costs inflicted with renovation. Adaptive ‘soft solutions’ pose an...

Curved concrete crownwalls on vertical breakwaters: Finite Element Analysis

Gísladóttir, Lára (author)

Crownwalls are often placed on top of vertical composite breakwaters to reduce overtopping. Adding a seawards facing overhang at the top of crownwalls has successfully reduced overtopping even further without increasing the freeboard of the crownwall. Crownwalls with a fully curved (FC) face are most often used in seawalls where they are...

Wave radiation from offshore pile driving for non-symmetric force fields

El-Ghalbzouri, Amal (author)

Monopiles are by far the most chosen foundation option for most off-shore activities. The installation of the foundation is commonly done by impact pile driving. The biggest issue of the traditional pile driving method is the sound emission, which reaches levels that are harmful to the immediate environment. Partly because of this, an...

Dynamic Response of an Orthotropic Bridge Deck Subjected to EOVs: A Case Study of the Haringvlietbrug

Kockelkorn, Tycho (author)

The Haringvlietbrug, which was delivered in 1964 and connects the island of Goeree-Overflakkee to the Dutch mainland, approaches the end of its lifetime. Rijkswaterstaat and Witteveen+Bos investigate the potential use of vibration-based structural health monitoring (SHM) to track deterioration. In vibration-based SHM, a change in the structure’s...

Extended application of timber for gates of existing locks

Groeneveldt, Niels (author)

Many navigation locks in the Netherlands under management and maintenance of Rijkswaterstaat need to be replaced or renewed in a sustainable way before 2050. In order to achieve this goal, Rijkswaterstaat is planning to renew as sustainable and cost-effective as possible. Most of the navigation lock gates that have been renewed in the last...

Adaptive design of flood defence systems: Incorporating adaptive design methods to cope with sea level rise uncertainty in a system-to-structure approach in the Rhine-Meuse estuary

Vrinds, Thijs (author)

Climate change is increasingly becoming more impactful on our society. Recent events such as the extreme rainfall in the summer of 2021 in Germany, Belgium and The Netherlands and hurricane Ida in Mississippi (USA), caused severe floodings and damages in these areas. Climate change, in turn, leads to an increase in sea level rise, making flood...

Experimental research on the factors which influence the fleeing time and rescue time of people evacuating flooded areas

van den Bulk, Marion (author)

The floods of 1953, 1993, 1995, 2021 and the almost flood in Rivierenland show that floods have major consequences. Before a flood people can evacuate preventively or vertical and during a flood people can flee, being rescued or permanently stay behind. This research focuses on fleeing and being rescued to a safe region. The research question is...

The New Haringvliet barrier: Conceptual design for the storm surge barrier of the Delta21 project

Onwuachu, Robbert (author)

The combination of continuous sea level rise, and more frequent extreme river discharges will become a rapidly developing problem for the Rhine-Meuse delta over the course of the next century. The current Dutch delta management policy mostly revolves around the consistent improvement of the existing dikes to account for the increasing water...

Bescherming van Noordzeekanaal tunnels tegen scheepvaart calamiteiten: Casus Velsertunnels

van der Heijden, Mark (author)

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...

The effect of timber bands and columns on the seismic behaviour of rubble stone masonry: A numerical study on Nepal's proposition for reconstruction of residential buildings

van Hoogdalem, Carlijn (author)

This research investigates if confining rubble stone masonry by timber bands and columns increases resistance against earthquake loads, by performing a number of numerical analyses in the finite element software program Diana. In order to establish a reliable model, the input parameters are investigated by means of a literature study and...

The historic quay walls of Amsterdam: A study into the hidden structural capacity of masonry quay walls under the condition of a partly failing foundation

Voortman, Rick (author)

The city of Amsterdam contains about 1600 bridges and 600 kilometres of quay walls. Of these walls, about 200 kilometres are of masonry walls placed on a timber floor and founded on timber piles. These quay walls are sometimes over 100 years old. Due to the increasing loads in the past century and the degrading of material properties in the...

Reliability updating of existing quay walls based on the effects of past performance: Introduction of a novel mathematical application in the probabilistic assessment and evaluation of quay walls

Laghmouchi, Kamal (author)

In practice, many structures among which quay walls are designed according the Dutch national guidelines (CUR). Dutch national practical guidelines (NPR), with guidelines for renovation, is still in development for the building industry. These guidelines follow the Dutch Norms (NEN) and Annexes. The guidelines propose procedures in which newly...

Structural Optimisation and Behaviour of the Breakwater Integrated Oscillating Water Column Device: A Combined 3D CFD and Structural Analysis

Goeijenbier, Bart (author)

The Oscillating Water Column (OWC) device is one of many available technologies for generating electricity from water waves. It is a caisson-like structure, which houses a water column in an enclosed chamber with an inlet at the bottom. Waves enter the device, exciting the water column. The trapped air above is forced out through a turbine,...

Urban quay walls: A numerical study to recognize foundation defects via masonry damage patterns

Grund, Mitchel (author)

The city of Amsterdam has a large number of old quay walls with rotten foundation piles. These foundation piles need to be identified and measures need to be taken. The urban quay walls are supported by two types of foundation: pinewood piles, which are easily affected by bacterial decay and spruce piles. To understand the mechanical behaviour...

The dynamic behaviour of hydraulic structures caused by wave impact loads: Enhancing the present design method in time and space

Sleeuwaegen, Shannon (author)

At this moment hydraulic structures are designed based on a simple method: the Dynamic Amplification Factor (DAF) method. This method does not consider the full dynamic interaction between the wave impacts, structure and water. The research project DynaHicS focusses on the dynamic behaviour of hydraulic structures, taking into account fluid...
