The Netherlands are protected against extreme high waters from the sea by an ingenious system of barriers. One of the most famous ones is the Maeslant barrier in the New Waterway near the port of Rotterdam. This barrier however, is subject to discussion, as it might not function as intended, because of the following reasons. It has a very low...

Dutch flood protections are assessed every five to six years in a nationwide safety assessment round. During the last assessment round large dike stretches in the Dutch Wadden Sea could not meet the safety requirements, and were assessed with failure. Dike strengthening is therefore needed in these areas. However, in front of these dike salt...

For decades, sub-sea pile driving has been performed to safely attach offshore and sub-sea infrastructure such as jackets, templates and manifolds to the supporting soil. In sub-sea pile driving, a hammer is lowered from an installation vessel and similarly descended until the (generally steel tubular) pile reaches his final penetration depth....

A group of islands will be constructed in the lake Markermeer to act as nature reserve for birds, called the Marker Wadden. These islands will be constructed out of soft clay, dredged from the bottom of the lake. Building with soft cohesive soils, also referred to as mud, is still a largely unknown territory. Traditionally, sand is used for land...

This research investigates approaches to conduct an efficient sensitivity analysis of wave forcing in coastal erosion studies. For this three speed-accuracy trade-offs have been assessed: (i) between the use of a simple and a complex model, (ii) between the use of several methods for conducting a sensitivity analysis, and (iii) between the use...

As a consequence of extracting gas from gas fields in the subsoil of the Groningen province during the last decades, seismic activity is increasingly encountered. As The Netherlands is not located in a seismic active area, dynamic loads due to earthquakes historically are not taken into account in structural design. The dynamic loads from...

Indonesia has planned to develop 24 main ports to support inter-island maritime highway concept. It has envisioned to balancing the trading activity between the eastern and western part of Indonesia. Nevertheless, trade problem in Indonesia also is caused by inefficient hinterland transportation to/from the port, thus increase transport cost....

Due to the removal of mangrove forests, the coastal zone of Demak district has suffered from severe erosion. One of the proposed solutions to restore the sediment balance and encourage mangrove re-establishment, is the construction of semi-permeable dams. This study aims to optimise the design of such structures. A 2DH site-specific model was...

The city of Amsterdam increases with approximately 10,000 inhabitants per year and Amsterdam-North is strongly under development attracting housing, employment and (re)creational activities. This is expected to induce a growth of 65% in pedestrians and cyclists, referred to as slow traffic. crossing the river IJ in 2025. The city ferry system,...

Five years ago, the Great Eastern Japan tsunami devastated a large part of Tohoku area (Northeastern Japan), and since then, other coastal areas in Japan have feared the possibility of such a large tsunami. This challenge of reducing flood vulnerability of coastal areas due to tsunamis has been discussed with high importance amongst the...

Sheet pile walls are increasingly applied in the Netherlands to reinforce dikes. Up to now it is not known what is the real strength and stiffness behaviour of this sheet pile walls and when the dike with the construction can be considered to have failed. Nowadays an elastic design is applied for reinforcements with sheet pile walls, while for...

Offshore wind turbines are exposed to complex irregular and highly fluctuating environmental conditions. The analysis is, therefore commonly performed in the time domain, resulting in a time consuming and computationally demanding optimization process. In order to reduce the computational cost, an optimization approach using the principle of...

Aquatic vegetation attenuates local currents, dampens wave energy and promotes sedimentation. Its function as shoreline defence has gained strong interest in the recent years, since it may offer sustainable and cost-effective solutions to coastal protection problems. Predictions of wave dissipation by macrophytes require understanding of the...

The present state-of-the-art modelling tools (such as FAST, BLADED) used for modelling an offshore wind turbine (OWT) are too detailed and computationally expensive. These tools are required only at detailed design stages of a project. For the preliminary phase, however, a much simpler (yet reliable) 3D model can improve and speedup the design...

A survey dataset taken at the Sand Engine mega-nourishment on the southwest coast of Holland was analyzed in an attempt to locate beach scarps and characterize their development. A beach scarp is defined as a vertical discontinuity in the upper foreshore slope generated through the removal of sediment by natural processes. More specifically,...

Fire Island has been monitored since Hurricane Sandy (2012). During that period, Fire Island showed recovery (accretion on the island). Behaviour of the recovery is not yet well-known. Main processes during the recovery are also not known. Therefore, the emphasis of this thesis is on the understanding of the main processes of the recovery of...

The Hollandsche IJssel is a river between Rotterdam and Gouda and is protected from the main river system in the Netherlands by a storm surge barrier. The Hollandsche IJssel experiences several problems: the storm surge barrier dates from 1958 and has a relatively low closure reliability; three quarters of the dikes have been rejected according...

The offshore industry and especially the oil and gas production, has faced a remarkable growth in the last decades, causing an increase in the population of offshore structures. The overwhelming majority of these structures are bottom founded and mostly made out of steel. Over these decades much experience has been gained with the design and...

Coastal regions change continuously due to natural processes. Human activities in coastal regions require a steady environment. Usually the dredging industry is contacted for coastal maintenance. Knowledge about the time development of sediment volume changes in specific regions is necessary for risk assessment in contracting. Nearly a century...
