Over one hundred scour holes are located in the Rhine-Meuse delta. These scour holes have relatively large depths and steep slopes and could pose a risk to the stability of river banks and hydraulic structures, especially since some scour holes are still growing. Scour holes develop at locations where either the hydrodynamics or the erodibility...

Floating Production, Storage & Offloading (FPSO) units are extensively utilized in remote offshore areas for deep water developments where a pipeline infrastructure is not an economically viable solution. Traditionally, FPSOs are converted from oil tankers, which entails that they are not equipped with an appropriate mooring system. A spread...

The river Rhine is subject to a multitude of controls imposed by nature and humans. Natural controls refer to climate and tectonics, while human activity is represented by a series of interventions aimed at flood protection, navigation, land reclamation and exploitation of river supplied resources such as hydro energy and sediment. These...

A crown wall is a gravity based L- shaped concrete structure on top of a rubble mound breakwater. Functions of a crown wall are: reduction of wave overtopping, enable transport on the breakwater and placement of pipelines on top of the flat surface. Marine contractor Van Oord was awarded to extend a breakwater with a crown wall on top, located...

220 miles offshore the West-Australian coast lies the Ichthys Field. In 2013 Heerema Marine Contractors (HMC) was contracted to install the umbilicals, risers and flowlines for the Ichthys Project, including the installation of several in-line structures such as in-line tees (ILT) and flow-line end terminations (FLET). The ship assigned to these...

To protect the hinterland, flood defences are often located on the border between water and land. This same border however is also an attractive place to live, which may hamper improvement of flood protections. Closing off a tidal (river) system, especially in case of little discharge, may in this case be a logical consideration. This would...

Wave overtopping in harbour areas is a fairly untreated topic in the context of flood risk analyses. Pragmatic approaches were undertaken to evaluate the possible influence of wave overtopping on the frequency of flooding. However no consensus was reached on how wave overtopping in a harbour area could be quantified. Therefore it is also...

Estuaries are complex systems that show a variety of hydrodynamic conditions. These conditions are influenced by bathymetry, geometry, climate characteristics, interacting fresh and salt water flows, and mixing effects caused by winds and wind-waves. The interaction between fresh and salt water flows in combination with mixing effects caused by...

River systems are vastly changing environments, not only due to natural process, but also human intervention plays an important role. With the many different river functions at play, large amounts of maintenance budgets are associated with river management. For decision makers it is important to know expected costs or losses and the spread...

Robustness is a hard-to-grip concept within engineering. This master thesis uses a framework to quantify the level of robustness that has been proposed by the Joint Committee on Structural Safety to assess the influence of the reliability requirement of a structural element. The lock complex at Weurt (the Netherlands) has been used for a case...

In order to accurately predict passing vessel interaction forces, different simulation tools have been developed over the years. Many of these are based on a double body flow approach. MARIN (a hydrodynamic research institute located in the Netherlands) developed a simulation tool called the FlowInteraction (FI) module, which is part of the...

The coastal protection system of the Dutch low-lying hinterland is under increasing pressure due to growing population and high economic value combined with climate change and a rising sea level. Supplying sand to dunes, beach and shoreface by means of nourishments is a widely applied technique to increase coastal safety. Climate change and a...

During Abandonment and Recovery (A&R) operations, steel wire ropes (figure 1) can experience torsional deformation. This deformation is a result of the helical configuration and the tension gradient in the rope due to its self-weight. The latter is very high when the ropes are used in deep water operations. Since the static component of the...

After the Deepwater Horizon oil spill in 2010, oil was released into the Gulf of Mexico and partly reached the shorelines. Here, it mixed with sand in the surf zone to form sand and oil agglomerates (SOAs). These cm-sized particles are heavier than water and are therefore found on the seabed. Years after the initial formation of these particles,...

The use of the detached offshore submerged breakwater (SBW) for coastal protection has an increasing popularity due to its low aesthetic impact on the natural environment. Submerged breakwaters however have only rarely been adopted and therefore its efficacy remains largely unknown (Ranasinghe et al. 2010). Shoreline erosion has been reported in...

An important step in the design process of breakwaters is the laboratorial tests which show the performance of the breakwater. One of the important aspects in the performance is the stability of the armour layer. A common methodology for breakwater testing is a method in which the design wave conditions are simulated in four steps of 1000 or...

The first quay walls were constructed in 2400 BC and were constructed with bricks. Since then, the quay walls have developed a lot. The quay walls nowadays are constructed out of steel, concrete or a combination of both materials. An upcoming material in the field of hydraulic engineering is fibre reinforced polymer (FRP). FRP has several...

The fairway connecting Holwerd and Nes forms the main transport route between Friesland and Ameland (the Dutch Wadden Sea). It consists of several tidal channels that funnel the majority of the tidal currents propagating through the tidal basin. Over the past decades, several channel bends have expanded leading to a fairway length-increase of...
