Abstract

This report results from a collaborative study by Hydraulics Research, Wallingford, and Queen Mary College, London, on the design of rock armouring. It presents results of recent hydraulic model studies, and discusses the effect of these recent advances on design methods. The research study was concerned principally with the hydraulic performance of rock armour of different shape and roughness characteristics. Over sixty laboratory tests with random waves were conducted to determine the armour movement/stability performance for an impermeable 1:2 slope armoured with rocks of five main shape types.
