The RMBFM-Project (Rubble Mound Breakwater Failure Modes) is sponsored by the Directorate General XII of the Commission of the European Communities under the Contract MAS-CT92- 0042, with the objective of contributing to the development of rational methods for the design of rubble mound breakwaters. 11 institutes from the European Union...

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...

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.

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 purpose of the model investigation reported herein was to obtain design information for stone and dolos armor used on breakwater heads and subjected to breaking waves. More specifically, it was desired to determine the minimum weight of individual armor units (with given specific weights) required for stability as a function of sea-side...

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...

On request of the companies Ballast Nedam and Havenwerken BV, Amsterdam, the Delft Hydraulics Laboratory has carried out some tests on a composite type breakwater for the harbour of Saldanha Bay, South-Africa, as an alternative of the original design of a spending beach. The tests served to establish a preliminary design of a breakwater cross...

Meer in het bijzonder is het onderzoek gericht geweest op de volgende punten: - Het ontwikkelen van stortpatronen voor die gedeelten van de dammen die met behulp van de blokkenvaartuigen worden gebouwd. Tijdens de uitvoering zal dit stortsysteem eventueel kunnen worden aangepast aan de opgedane praktische ervaringen. Als gevolg van de gekozen...

Bij het begin van de stabiliteitsproeven voor de havendammen te Scheveningen in de windgoot van het Laboratorium te Delft lijkt het nuttig de voorbereidende discussies samen te vatten en een overzicht te geven van de mogelijke dwarsprofielen. Het huidige overzicht kon ten opzichte van het eerder (medio 1965) verschenen exemplaar sterk te worden...

In opdracht van de Rijkswaterstaat, Arrondissement Rotterdamse Waterweg, is door het Waterloopkundig Laboratorium in de windgoot van het laboratorium "de Voorst" een modelonderzoek uitgevoerd naar de golfoploop en de golfoverslag voor een aantal ontwerpen van de Nieuwe Zuiderdam te Hoek van Holland. Deze havendam zal ter bescherming dienen van...
