01-01-1999 0183 32 This chapter describes the processing of the blocks or fragmented stone after removal of the rock from the mine or quarry face The processing of armourstone and rock fill have much in common and armourstone will be taken to include material intended for coastal protection as well as other forms of hydraulic stone and rip-rap used to prevent erosion of ,...
01-01-1999 0183 32 Man has been involved in the construction of harbours and the protection of vulnerable sections of the coastline since antiquity The use of large blocks of rock to armour such structures also has a long history, but it is only within the last century that the design of structures using natural rock materials has been treated scientifically...

graded armour classes have a higher porosity than wider graded armour classes and therefore higher permeability, which increases the stability of the structure and decreases both the overtopping and reflection from the structure One of the aims in designing an Icelandic-type berm breakwater is to maximise the possible output of the...
