This book presents an experimental study on wave reflection on coastal structures and current state of the art anti-reflective designs of breakwaters. In particular, this book shows the results from an experimental study on a new low-reflectivity quay wall caisson based on the MUCAR patent. The original idea of a multi-cell circuit scheme consisting of connecting caisson cells in two different directions to create circuits of appropriate length to optimize the given response to low-frequency incident waves was considered. Results from twelve 1/35 scale physical model tests, carried out at the...
