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...

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...

Analysis of sea states in deep water. - Discussed will be the difficulties of an analytical solution for the wave period and the wave height probability - The closed solution for the wave height probability in the limit of the band-width approaching zero - The closed solution for the wave height probability in the limit H/sqrt(m0)->inf. - The...

Water waves break as they advance over a gently sloping beach for all off-shore sea states except for the calmest conditions. Most theoretical, experimental and field studies have been directed to this type of wave breaking, yet waves can break with greater violence on steep slopes and close to coastal structures and cliffs. Further, on those...

Surf zone dynamics is a highly complicated topic in hydrodynamics which deals with the waves and wave generated phenomena in the region between the breaker line on a beach and the shoreline. When waves break on a gently sloping beach, large amounts of energy are released and turned into turbulence. As the waves keep breaking and interacting with...

The present lecture deals with models for situations in which the spatial dimensions cannot be separated according to the scales of the morphological processes. Rather common examples of such situations are the morphological evolution near structures (e.g, breakwaters), river outflows, tidal inlets, etc. But also in the absence of such distinct...

Kraus, N.C. (author)
In this chapter we consider beach profile and cross-shore sediment transport processes commonly encountered in coastal engineering applications. Main emphasis is on beach profile change produced by direct wave action, and our assumption will be that longshore transport processes are constant along the profile. Present engineering knowledge of...

An analysis of "soft" measurements, in the form of beach nourishment, to protect ourselves against the sea. The rapport covers the following subject with regard to "soft" measurements: - Design of soft solution: review of design tools, practical consequences of morphological theory and failure modes - Construction methods for soft solutions:...

During the last few decades the believe that absolute security could be provided has been recognized to be mistaken in many branches of engineering. This happens as a consequence of the imperfect predictability of load intensity, structural characteristics and structural behavior, as well as a consequence of human gross errors during the design...

Dalrymple, R.A. (author)
The propagation of waves from offshore to onshore is a difficult problem due to the mathematical complexities of the governing equations and the degree of uncertainty of the bathymetry over which the waves must travel. In this lecture, the various methods of transforming offshore wave trains to shallow water are discussed. First, single wave...

The project to protect Venice against periodic flooding appears to be a complex problem due to the city and surrounding environment that are extremely fragile, the presence of the port activity and the hazard of perturbation of the physical, chemical, biological equilibrium of the Venice lagoon. The mobile barriers are one of the components of a...

Bijker, E.W. (author)
The motivation to develop a transport formulation for the combination of waves and current has been the necessity to model longshore transport passing tidal in- and outlets. The generally applied C.E.R.C. formula for the longshore transport is not applicable here because that formula relates the longshore transport to the longshore current...

The design and construction of structures for the coast lines of the world must consider numerous forces and factors. These include the purpose of the structure, the design waves, the design wave climate, the material of which the structure is to be built, foundation conditions, earthquakes, tsunamis, availability of construction and maintenance...

The historical development of upright breakwaters in Japan is briefly reviewed as an introduction. Various wave pressure formulas for vertical walls are discussed, and then the design formulas currently employed in Japan are presented with an example of calculation. Several design factors are also discussed.

In general a safety factor or a conventional partial coefficient is used for the design of structures at sea. These methods are classified as Level I (deterministic) methods. However, such approaches do not allow the determination of the reliability (or the failure probability) of the design, and consequently it is neither possible to optimize,...

The safety analysis of marine systems is studied. One assumes that the required results of the hazard analysis are available. The identification of the appropriate performance function and the relevant reliability calculation are discussed in detail. The procedure is exemplified for some basic categories of marine systems.

Structural approaches can be employed to stabilize shorelines against erosion, to provide sheltered areas for swimming or for a myriad of other benefits. In this section, the emphasis will be on shoreline stabilization although much of the information and discussions presented would be equally applicable to accomplish other objectives. Three...
