The objective of the study is to conduct a survey to assess the hydraulic performance of a range of
coastal structures with respect to the energy transformation processes. In doing so attention is
wave reflection in view of its importance with respect to the long term
hydraulic performance of coastal structures. Since the structures investigated did not include low
crest structural configurations, wave overtopping was not considered in this study. Most of the
structures which were reviewed refer to coast protection structures of the revetment/ seawall type.
Hence external transmission was only considered in the case of armoured porous trapezoidal
structures.
