The goal of achieving net-zero emissions by 2050 requires innovative ways to reduce energy consumption in all sectors. This thesis presents an in-depth analysis on the effect of coastal currents on energy consumption of sailing dredging vessels and the potential to make use of these currents to minimize energy consumption in dredging projects....

Knowledge of nearshore bathymetry is crucial for every aspect of the blue economy. Currently, it is expensive to obtain nearshore bathymetry at regional scales, and therefore this data is not available for many coasts. The data scarcity occurs especially in the global south and big ocean states that are at the highest risk from climate change....

Remotely Operated Vehicles (ROVs) are positioned relative to an underwater acoustic positioning system: Ultra-Short BaseLine (USBL). The accuracy is affected by refraction artifacts, caused by the variations of the sound velocity in the water column. Accurate positioning would require continuous measuring of the sound velocity profile (SVP)...

Coastal flood risk is expected to increase over the 21st century as a result of climate change and economic growth, which makes low-lying regions especially vulnerable. Global screening techniques are needed for a more widespread use of NBS in these flood prone coastal regions. This research expands on the current assessments done by developing...

This thesis introduces a new algorithm for optimising shipping routes within a dredging project. Highly dynamic and time-dependent hydrodynamic features influence shipping routes. Due to the complex interactions between the horizontal tide, vertical tide, stratifying forces, wind-driven forces, and limited water-depth, shipping routes were...

Subsea Rock Installation vessels cover pipelines, which transport oil from oil and gas fields. This is done by means of a flexible fallpipe until depths of 1000 meters. Around the Shetland Islands, the workability of the vessels at two specific project locations is compromised by the conditions in the ocean. In this research, data from a 3D...

Troost, A.P. (author)
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...

Van Oord is currently building the Gemini Wind farm in the North Sea. It is located 80km North of Schiermonnikoog. Before execution started some wave and current analysing buoys have been deployed to investigate the currents on the location of the wind farm for workability and insurance purposes. In this report the ADCP-current data will be...

The topic of this paper is the study of the tidal velocity profiles within a region of fresh water influence (referred to as ROFI in this paper). These regions of fresh water influence occur where rivers discharge fresh water into salty seas. The main research question is how depth influences the behaviour of the tidal velocity profile in a...

Stam, G.N. (author)
Recently, nourishments have been carried out on a large scale to counteract the on-going erosion along the Dutch Coast. The main advantage of these large beach extensions is that large stretches of coastline are protected for a long time scale (e.g. 20 years), which decreases the frequency of nourishing significantly. This is not only cost...

Kalpias, A. (author)
The longshore sediment transport (it will be referred also as LST) is a core issue in the field of coastal engineering. It is among the most important nearshore processes that control the coastal morphology, and determines in large part whether shores erode, accrete, or remain stable. Consequently, it is important to be able to calculate the LST...

In this master thesis the residual circulation in the North Sea is investigated. It has been shown that the numerical models used in this thesis (DCSMv5 and DCSMv6) give a rather low representation of the actual circulation pattern in the North Sea. The dominating forces which cause residual currents in the North Sea are the tidal forcings,...

After decades of coastal erosion in the north-west area of the Island of Texel, the shore-normal `Eierlandse Dam` had been built in 1995. The dam, situated in the outer delta of the Eierlandse Gat tidal inlet, resulted in a remarkable short-term morphological development of the adjacent coast. Four years following completion of the dam, large...

Shore-parallel submerged breakwaters (SBWs) appear as an attractive form of coastal protection. Compared to their emergent counterpart there is no impact on the beach amenity and aesthetics. In addition, there is a possibility for recreational purposes. However, the actual application of SBWs is often discouraged because the complexity of the...

The Open Geospatial Consortium has been developing a wide range of open standards for the field of Geographical Information (GI). One of the standards allows for remote processing; the Web Processing Service (WPS). WPS has not been implemented in many project yet but it is a promising standard which can also be applied outside the field of GI....

The study presents an assessment of sustainable practices for applying sand nourishments aiming long term coastal protection and development. Such concepts are applied in three study cases: Sylt (Germany), S'Abanell (Spain) and Ghanaian coast.

East Coast Park is a 15 km long coastal park along the southeast coast of Singapore. It is built on entirely reclaimed land and comprises a sandy shoreline. The beaches along this shoreline are formed due to the implementation of anthropogenic structures all along this stretch of coast through so-called headland control. These structures were...

For many applications in the field of coastal engineering 2D-morphological models are being applied. Due to the large computational effort these models demand it is nearly impossible to include a full wave climate in long-term morphological modeling. This has asked for waveclimate reduction methods in order to reduce the input and consequently...

In 2003, a first proposal for identification of seaward development, preliminary in combination with residential building, was presented in the Chamber of Deputies and within the States-Provincial (South-Holland), by respectively Geluk and Waterman. In response to this proposition, the ministry started an investigation, but concluded there was...

Becker, J.H. (author)
Nowadays, the ecological effects of dredge plumes are usually managed based on the precautionary principle. Predictions of suspended sediment levels are made, which have to be compared to thresholds set by the responsible authority. Failing to comply may cause a project to be delayed and thus lead to additional costs. The precautionary principle...
