WAVE TRANSMISSION AT LOW-CRESTED STRUCTURES, INCLUDING OBLIQUE WAVE ATTACK

A part of the DELOS research focused on wave transformation at low-crested structure and is summarised in this paper. Several flume tests have been carried out within the project to analyse wave transmission on rubble mound structures and simultaneously an existing database has been extensively increased by receiving data from other researchers in the world. This new database consists of more than 2300 tests and has been used to come up with the best 2D wave transmission formula for rubble mound LCS. Oblique wave attack on LCS was a second objective within DELOS. Small scale model results were produced and analysed leading to new transmission formulae for smooth LCS and to conclusions on 3D effects for both rubble mound and smooth LCS.
