Abstract: An alternative to rubble mound construction, with or without precast concrete armor units, is recommended which comprises flexible membranes filled with cement mortar in situ. The placement of these for greatest stability ...

Abstract: The simple case of sand accretion behind an impermeable breakwater parallel to the shoreline with normally incident waves is treated. The cuspate foreland or salient so formed has an apex whose location from the breakwater ...

Abstract: Waves impacting on breakwaters, even of rubble‐mounds, are reflected efficiently from them, so producing almost standing waves for normal approach and a complex short‐crested wave system for oblique approach. In the former, ...

Abstract: The reason for submitting one more scenario to this spectacular failure is that it may prevent a similar occurrence. It is suggested that failure was due to bed subsidence or liquefaction, so causing the supporting rubble ...
