The coastal team of Delta Marine Consultants [DMC] have taken the initiative to develop a new concrete armour unit for application on breakwaters and shore protections. Following the preliminary model tests conducted at DMC, 2-D hydraulic model tests have been carried out at Delft Hydraulics in October 2002. The experimental set-up and test...

Takahashi, S. (author)
In this book, different types of breakwaters are introduced and their historical development is described in order to understand the advantages and disadvantages associated with each type of breakwater. The failures of breakwaters are then discussed to demonstrate crucial points in their stability design. Finally, the design methods used for...

This text introduces the ‘Detailed scientific and technical report’ of the MAST III project MAS03- CT97-0116 ‘The optimisation of crest level design of sloping coastal structures through prototype monitoring and modelling’ (acronym: OPTICREST). This report gives an account of the detailed scientific and technical outcome of the project referring...

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 Core-Loc, invented and developed at the Waterways Experiment Station (WES), is a new-generation, optimized breakwater concrete armor unit for protecting shoreline and navigation structures.Because of the very difficult construction, in-service, and repair conditions associated with high-energy wave environments, a need was identified to...

in this study an analysis concerning the pulsating and impact portion of the tensile stresses inside tetrapod armour units is presented. The data has been obtained from a series of small scale model tests performed at Delft Hydraulics. Stresses have been measured using a load cell technique developed and made available by Coastal Engineering...

The paper presents a design formula for Tetrapod armour on a 1:1.5 slope exposed to head-on random wave attack The formula predicts the relative number of broken Tetrapods as function of: the mass of the Tetrapods, the concrete tensile strength and the wave height in front of the structure. Thus, the formula addresses the observed problem of...

The slender, complex types of armour units, such as Tetrapods and Dolosse are widely used for rubble mound breakwaters. Many of the recent failures of such structures were caused by unforeseen early breakage of the units, thus revealing an inbalance between the strength (structural integrity) of the units and the hydraulic stability (resistance...

The rational design diagram for Dolos armour should incorporate both the hydraulic stability and the structural integrity. The previous tests performed by Aalborg University made available such design diagram for the trunk of Dolos breakwater without superstructures (Burcharth et al 1992). To extend the design diagram to cover Dolos breakwaters...

The wave motion on-and-in Berm breakwaters as well as the reshaping process have been studied. Measurements were carried out to study wave interaction with a reshaped Berm breakwater. These tests were used for verification of a numerical model capable of simulating both the wave motion on as well as inside the structure. This numerical model has...

Measurements in a U-tube tunnel were carried out to study flow through coarse granular material. Tests with stationary flow and tests with oscillatory flow were done to study the differences between both. The coefficients from the extended Forchheimer equation, which is supposed to describe non-stationary porous flow, were determined. It...

This manual gives information about how to use the P.C.-model ODIFLOCS. The wave action on and in several types of coastal structures can be computed. The necessary input data and the output data have been described. Although many phenomena are implemented in the model, which resulted in rather accurate predictions of several properties, further...

This paper gives first an overall view of physical processes involved with rubble mound structures and a classification of these structures. After the description of governing parameters, the hydraulic response is treated. This is divided into: - Wave run-up and run-down, - Wave overtopping, - Wave transmission, - Wave reflection. The main part...
