Blue energy is a technique that converts the difference of molar free energy between fresh river water, and salt sea water into electricity. Theoretically, 1,5MW can be won when mixing flows of 1m3/s of river water with sea water. Taking into account all losses that occur in the system, makes that the net power is approximately 1,0MW/m3/s. For a...

A process-based numerical model was applied to investigate wave reworking in the deltaic environment. The two main objectives were (1) to develop this model and (2) consequently apply it to study the effects of wave reworking on the morphology and stratigraphy of a delta. A depth-average Delft3D model with two sediment fractions (fine silt and...

The erosion problem in Hai Hau coastal district (Vietnam) is the subject of this thesis. The exact processes that drive this ongoing erosion however are not well defined yet, and therefore two main goals are defined. The first goal is to gain more insight into the processes that drive the ongoing erosion in Hai Hau. The second goal is to predict...

In the year 1991 the Technical Advisory Commission (TAW-A4) ordered a full scale investigation on wave impacts on an asphaltic concrete revetment. The goal of the experiment was to gain insight into the mechanisms which would lead to failure, cracking of the revetment. Also the behaviour of the revetment after failure (residual strength) was...

The safety of a large part of the Netherlands depends on sea dikes. Due to climate change, a sea level rise is predicted. Together with stronger storms and more wave attack, wave overtopping on the current dikes will increase. As a response, crest levels of the dikes need to be raised in order to meet the present regulations for wave overtopping...

In a consortium Iv-Infra has made a proposal for a storm surge barrier to protect the city of New Orleans against hurricanes like Katrina. The design is a pile supported concrete structure with a considerable complex superstructure. The superstructure of the reference design consists of a perforated inclined wall and a vertical back wall. Since...

This thesis is about the stability of toe material for rubble mound breakwaters in depth limited conditions. The present equation, Van der Meer 1998, gives results for depth limited conditions but is not validated. The empirical equation is based on physical model tests done by Gerding 1993. The Van der Meer equation implies deep water and...

The objective of this thesis is to improve the insight into the morphological processes in the outer delta of the Westerschelde estuary, especially those related to the sediment exchange between the delta and the estuary. The main residual sediment transport patterns in the delta have been found to look as follows. On a large scale there is a...

This research has focussed on the identification of the relevant processes behind the long-term fine sediment dynamics. Three main influences were considered: the tide, wind waves and biological stabilization/destabilization. The study was performed by means of computational modelling, within the process-based model, Delft3D. By modelling...

This thesis concentrates on the autonomous behaviour of the breaker bars in front of the Holland coast in the period 1965-2006. The breaker bars in front of the Holland coast show a seaward movement, starting small at the waterline, growing during their seaward motion and dying out at deeper water. A typical profile in front of the Holland coast...

The rise of sea level (18 to 91 cm in South Australia by the end of the 21st century) will result in beach erosion and, hence, poses a significant risk to the beaches of southeast Australia. This risk can be mitigated by means of beach nourishment. The costs of applying beach nourishment to the coast of southeast Australia in the 21st century...

For local protection of coastal stretches where buildings are situated in or form part of the coastal defense line the deep water reef concept has been developed. Two reef concepts were designed; a shore-parallel breakwater (of 3 km length) and a segmented breakwater (three blinds of 1 km length), both located in 10 m water depth at 1.5 km off...

Coastal erosion is a serious problem in several coastal areas in Vietnam. One of these areas is the district of Hai Hau, located in Nam Dinh province. This district suffers from severe coastal erosion, the coastline has been retreating for more than 100 years. Efforts have been made to stop this erosion which resulted in the construction of...

The Indian Ocean Tsunami has once again revived the discussion in the tsunami modelling community if the non-linear shallow water equations are a valid model for the propagation of tsunamis. It is suggested that the mechanism of frequency dispersion which is absent in these equations might be important in the correct modelling of large scale...

The Port of Thessaloniki is the second biggest port in Greece after Piraeus. Located in the Northern part of the country, it has a large hinterland above it, the Balkan Peninsula, which renders the Port a transit one. It is naturally protected from winds and waves and it is the best alternative for vessels coming from the Suez Canal and heading...

Elastocoast is a new type of revetment system for use as a cover layer on dikes. It consists of granular material (rocks), which is fixed together with a two-component polyurethane adhesive. In the Elastocoast system each individual rock is covered with a thin film of polyurethane. When the adhesive is cured, this film fixes the rocks together...

In September 2007 two prototype pilot tests were constructed along the Dutch coast with an experimental, polymer based revetment. An area of 490 m2 was put on a dike slope in the Eastern-Scheldt basin, and another 385 m2 on the horizontal surface of a beach groyne near the Pettemer Zeewering along the North-Sea coast. The revetment consists of...
