Van Dijk, B. Nederpel, A. Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 2003-01-01 Abstract Medium height breakwaters are subjected to a considerable amount of overtopping. This implies the armour on the inner slope has to stable against overtopping waves. Existing equations do lack some basic understanding of the process of starting up movement of rock on the inner slopes. In order to get more insight into this phenomenon a special device has been constructed in the laboratory. In this device it is possible to generate one single, overtopping wave. So with this piece of equipment overtopping of single waves can be repeated several times and a relation can be looked for between the individual plunge and the stability of the individual blocks. In an other research program the relation between the random waves and the individual plunges is investigated. As a follow up the results of damage by individual waves will be combined with the distribution of overtopping water over a breakwater. This combination will result in a damage distribution due to random overtopping. It has been found from the first test series that stability of the blocks can be described as a function of the maximum water velocity on the crest, combined with some geometrical parameters of the inner slope. From this research followed that the crest height and inner slope also had an effect on stability Subject riprapinner slopewave overtoppingbreakwaters To reference this document use: http://resolver.tudelft.nl/uuid:dc5f9b51-18c7-450a-af50-78dbb122b94b DOI https://doi.org/10.1061/40733(147)18 Publisher American Society of Civil Engineers ISBN 0784407339 Source Coastal Structures 2003: Proceedings of the 3rd International Conference, Portland, USA, 26-30 August 2003 Part of collection Institutional Repository Document type conference paper Rights © 2003 Verhagen, H.J.
