The influence of armourstone shape and rounding on the stability of breakwater armour layers

This is the second of two reports relating to a collaborative prograrmne of random wave flume tests to quantify the effect of rock shape on stability. The first report, SR 150, by Hydraulics Research, Wallingford, gives a summary of recent advances in design methods for rock armoured coastal structures and presents a detailed description of the...

Dynamic structural response of Core-Loc

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...

Xbloc armour unit development - hydraulic performance of Xbloc armour units, 2D model tests at WL Delft

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...

Riprap design for wind-wave attack, a laboratory study in random waves

In 1962 the Civil Engineering Research Association (CERA) sponsored laboratory tests which resulted in the publication of a report (1) giving design procedures for determining the riprap size required for given design wave conditions. the CERA work represents one of the first attempts to rel.te the results of tests using regular waves to those...

A critical review of the hydraulics of rubble mound structures

Forces by uprush and downrush, the imporatnace of permeability, the resonance phenomenon, friction between armor blocks and between armor and sublayer, slope geotmetry and practical design principles

Static stability of loose materials under wave attack: New design formulae and probabilistic approach

Overview of application of the Van der Meer formula in a probabilistic environment.
