Aircushion Supported Mega-Floaters

The increase of the global population and expanding coastal mega-cities will necessitate an innovative pursuit of the utilization of the ocean space in which mega-floaters will play an important role in the future. These types of structures are very large floating artificial islands that can be used for various facilities and purposes similar to...

Experimental study of wave forces on rubble mound breakwater crown walls

This paper has two main objectives: (1) to describe the experimental work carried out in order to verify the theoretical method from Martin (1995) for the calculation of wave forces on crown walls and (2) to show some results from field and lab measurements and compare these data to calculations from several analytical methods. The Principe de...

The application of spectral analysis in the determination of wave loads on vertical breakwaters

Vertical breakwaters are used in the design of harbours to create a protective area. This protective area can be an approach channel or the harbour itself. Because of large new projects, such as Maasvlakte 11 in the Netherlands and the increasing sizes of ships, many harbours have to be placed in deep water. Deep water requires higher...

Wave impacts on vertical breakwaters

The need for coastal structures, such as breakwaters, at great water depths is rapidly increasing as a result ofthe increasing draught of large vessels and off-shore land reclamations which can, for instance, be used for the benefit of the expansion of harbours and related industrial activities. In water depths greater than approximately 10 m...

Recent Italian Experience in the Design and Construction of Vertical Breakwaters

Italy is often considered as a mother country of vertical breakwaters for harbour protection, since they have been widely used all along our coasts long since. An updated location map is given in fig. 1, which also shows the position of the directional wave recording stations of the existing Italian network. The most common vertical breakwaters...

Mound Breakwaters under Wave Attack

Research on rubble mound breakwaters when confronted with waves. The rapport covers the flow characteristics and mound stability under regular waves and under oblique wave attack. The authors find a formula for rough, permeable slopes, flow characteristics under the action of a regular wave train by a function of the type. Furthermore they...

Wave shock forces: An analysis on deformations and wave forces in the wave and the foundation

At the inauguration of two advanced wind-wave flumes in the Netherlands, three decades after BAGNOLD's pioneer work, and one decade after the Haringvliet sluice investigation and the joint Dutch-Danish investigation of the Hanstholm breakwaters, it seems appropriate to summarize current knowledge on wave shock phenomena. These may be classified...
