Abstract

Experimental results are presented from which it is now possible to predict the threshold of movement of shingle. The experiments were conducted in an Oscillating Water Tunnel, (Ref. 1), on the threshold of movement of shingle size material. The Tunnel simulates the oscillatory water motion at the sea bed due to wave action with a semi-orbit range of 0-4.5 metres and a period range of 5-15 seconds. Additionally, a unidirectional current of up to 0.6 m/sec can also be superposed upon the oscillatory motion. Although limestone chips of between 0.32 cm and 2.5 cm diameters were the basic material tested, other materials such as coal and sand were examined in order to observe the effects of the various parameters over a wider range.
