This report gives information about the hydrodynamic coefficients of a box-shaped ship with zero speed of advance in case of pure swaying and yawing on shallow water. In the horizontal plane a harmonically oscillating motion is imposed on the ship; the hydrodynamic coefficients for the modes of motion of the ship are determined from the exciting...

In 2001 a DIOC-project was started at Delft University of Technology on the behaviour of mud in the water column. In this project the behaviour, spreading and settling velocity of fines is studied. After an introductional literature review on the behaviour of fines released due to dredging, the focus was placed on the behaviour of the fines on...

With the number of offshore wind farms rapidly increasing, in a wide variety of site conditions and using different turbine sizes, the need for alternative support structures other than the conventional monopile structure is apparent and several projects have been realised using other support structure types. In this report the results of Upwind...

Jack-ups have been constructed for numerous ocean environments, but to date there has been no operating experience under Arctic sea ice conditions. The current state of jack-up technology does not allow working outside the ice-free season and thus ice management will be needed to extend the drilling season. Currently, ice load calculations are...

Assessing swimmer safety along the Dutch coast entails more than only assessing the risk of rip currents. Seven criteria have been formulated to make a comprehensive assessment of swimmer safety along the Dutch coast. These are based on interviews with lifeguards, rescue report statistics and detailed lagrangian measurements of the current...

This study deals with the development of deep scour holes in the river bed of the Dutch Rhine delta in the Netherlands. Assessment of multi-beam surveys, laboratory-flume experiments, and 3D numerical modelling, shows how fast this type of scour holes grows in depth and width. These typical scour holes are found in the tidal deltaic rivers that...

Due to economic growth, Lagos Harbour is expanding. Capital dredging is needed to allow larger vessels to call the port. As harbour siltation is already a problem, increase of maintenance dredging is a worry. In the past no data was available to understand the hydraulics and sediment transport to estimate maintenance dredging volumes. This paper...

The performance of the spectral wind wave model SWAN in tidal inlet seas was assessed on the basis of extensive wave measurements conducted in the Amelander Zeegat tidal inlet and the Dutch Eastern Wadden Sea, as well as relevant data from other inlets, lakes, estuaries and beaches. We found that the 2006 default SWAN model (version 40.51), the...

Land reclamations and island coasts often involve strongly curved shorelines, which are challenging to be properly modeled by numerical morphological models. Evaluation of the long term development of these types of coasts as well as their response to storm conditions requires proper representation of the governing physical processes. Not all...

The earthquake and tsunami of March 2011 led to death and destruction in coastal areas in Japan. A seminar was held in June 2012 for Japanese and Dutch coastal researchers to discuss lessons for the management of the risks in coastal areas associated with tsunamis, typhoons and storm surges. The seminar has highlighted important practical and...

This study further develops the method of probabilistic design and to address a knowledge gap in its application regarding safety and reliability, risk assessment and risk evaluation to the fields of flood defences. The thesis discusses: - a generic probabilistic design framework for assessing flood defence systems; - statistical techniques in...

The Yangtze river (China) is one of the biggest rivers in the world in terms of length, area, discharge and sediment load. The large sediment supply by the Yangtze river resulted in the development of large coastal wetlands in its estuary, which form rich and important ecosystems. Human activities are increasingly influencing the Yangtze estuary...

The current research is aimed at finding a proper relation between flow forces acting on the bed and the bed response. To this end, experiments were carried out in which both the bed response (quantified by a dimensionless entrainment rate) and the flow field (velocity and turbulence intensity distributions) are measured. The three available...

Submarine outfall disposal of domestic and industrial sewage is a method of disposal of steadily growing importance. The flow from an ocean outfall is essentially that of a submerged horizontal or vertical jet. Thus a study of the hydrodynamics of such jets is needed to evaluate the dilution of the sewage flow. A study of this kind is presented...

Knowledgeof the yield strength of subaqueous sediment beds is essential to calculate their sensitivity to erosion and failure. Also for dredging operations yield strength is a parameter of the utmost importance. This report describes measurements of the yield strength profiles of cohesive sediment samples with a sounding instrument developed by...

Keynote lecture at the ICSE2006. Various types of scour can confront the engineer, who has to design and construct a hydraulic structure in a marine environment. The engineer is interested in the magnitude of the scour to be expected and its development in time. He hopes that such information, if at all available, is accurate and that he can...
