Conceptual Design of Rubble Mound Breakwaters

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...

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...

Design of rubble mound breakwaters

This rapport includes two main topics for designing a rubble mound breakwater: 1. Geometrical properties and durability of rock materials 2. Structural integrity of concrete armour units Included in this rapport are some design diagrams for Dolos of different waist ratios.

Design and Construction of Rubble Mound Structures: An Introduction

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 design of upright breakwaters

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.

Detached Breakwaters and their Use in Italy

Detached (or "offshore") breakwaters of emerging type are a common and effective approach for beach protection, particularly for areas with small tidal oscillations. This kind of breakwaters aims at acting on sediment transport by decreasing the transport capacity of long-shore currents, thus locally causing settlement of sediments. Unlike...

Detached Breakwaters

In this paper, the hydraulic functions and stability of detached breakwaters and submerged breakwaters with wide crown widths are discussed. The following subjects with regard to detached and submerged breakwaters are discussed: - Function of detached breakwaters in controlling waves and wave-induced currents - Function of detached breakwaters...
