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...

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...

The strength of the Atlantic Meridional Overturning Circulation (AMOC) will decrease due to climate change. However, the magnitude of this decrease is still under debate, since uncertainties exist about the driving mechanisms of the sinking branch of AMOC. Conceptual models have shown that sinking is located at the lateral boundaries of the...

Momentarily the determination of the static stability of rock on mild slopes can be split in roughly two paths, the empirical and the physical approach. However, both the approaches have their limitations from which one could conclude that neither approach is currently an accurate description of the stability of rock on mild slopes under wave...

To determine the nominal diameter of armour rock for a rubble mound breakwater, the ‘Van der Meer’-formula is frequently used. It requires the so-called 'notional permeability' parameter P, which has been defined for a limited number of structures. Often designed structures deviate from these defined lay-outs. To determine the notional...

This thesis report considers the topic of sustainable marina development. This term can be understood to be a combination of two terms; “sustainable development” and “marina”. Sustainable development in this research study has been considered in relation to the coastal zone and basically entails an approach to ensure a balance between the...

Prototype single layer armour units on a breakwater slope are observed to break. To predict when breakage occurs, the objective of this research project is to obtain knowledge on, and measurements of the rocking behaviour and failure mode of single layer armour units. A single cube on a breakwater slope is subjected to investigations. An...

Although mangrove forests have proven to contribute to wave dissipation significantly, these ecosystem are threatened mainly by the expanding aquaculture. International or nationwide applied greenbelt policies are often used for the preservation of the mangroves and hence the flood hazard reduction, without taking local (hydrodynamic) conditions...

The objective of this study is to identify the mechanisms that drive the morphodynamic behaviour of the sediment disposals in the subtidal zone north of the intertidal shoal Walsoorden. The morphological development of the sediment in the subtidal zone near this shoal has been monitored and measured. The gathered bathymetric data show that one...

Navigation locks are used to transport vessels between waterways with different water levels. In the nearby future many navigation locks will be renovated or replaced. During the design of a new lock still some unknown factors are encountered. One of these factors is the vibration of the valve. The valve is part of the filling and emptying...

Bank protections are currently constructed with stone, wood, concrete and steel. NETICS has introduced a sustainable and commercially very attractive alternative called the GEOWALL. The goal of this study is to find a viable field of application within the quay structures by considering the arising challenges of a larger scale wall. Additionally...

The number of wind farms that are commissioned, being installed, or prepared is still increasing due to a growing demand for green energy. To benefit from the higher wind velocities, which can be found at sea, and to prevent the pollution of the horizon, wind farms are being built offshore and installed in an ever increasing water depth. The...

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,...

One of the most economically and ecologically important issues related to coastal engineering is the preservation of the coastal areas. The mean to do so, is the good understanding of the sediment transport mechanisms that are involved in the transformation of coasts. In order to protect these valuable areas, man-made structures have been...

In this thesis, the improvement and extension of the North Sea Storm Atlas is studied. The North Sea Storm Atlas is a new statistical approach for rapid flood forecasting in coastal areas. The method is based on a large database of potential weather scenarios. A detailed hydrodynamic numerical model (WAQUA-in-Simona/DCSM98) has been used to...

Traditional reinforced concrete tunnels show limits regarding large spans in the transverse direction. There was a lack of knowledge whether the steel-concrete-steel (SCS) sandwich tunnel can be a solution for tunnels with extreme large spans. Research was needed to understand the structural response of a large span SCS tunnel to the load...

Within Royal HaskoningDHV an innovative concept is thought to be feasible as a new foundation for larger wind turbines in deeper waters. In this thesis the development of this innovative offshore wind turbine foundation was aided. The research focused on two topics: - Scour at this gravity based foundations. - Possible design optimisations with...

Liquefaction may have large influence on performance of anchored quay walls and is important to include in seismic design. Design codes provide evaluation methods that provide hardly any insight in the actual development of excess pore pressures and the don’t consider soil structure interaction. There is a need for tools that include these...
