THE MONITORING OF RUBBLE MOUND BREAKWATER STABILITY USING A PHOTOGRAPHIC SURVEY METHOD

摘要

A method of surveying the above-water slope of breakwaters by means of photography has been developed at the National Research Institute for Oceanology. The method is simple and inexpensive and yet capable of detecting movement or displacement of a single armour unit on a breakwater. This poster paper describes the method and presents some examples of its application in the field.
