The clarification on the collapse mechanism of a caisson breakwater has been an urgent task in order to reduce damages caused by next millennium tsunamis. In this study, piping destruction of a mound induced by seepage flow is taken into consideration solely. A stabilized ISPH method proposed by Asai (2012) is adopted with some modification associated with the extended Darcy law (Akbari 2013, 2...

Cmt Kennedy K. S. 1974. General history ot vestibular disorders in diving. Undersea Biomed. Res. ^rC '(I): 73-81.-The history of vestibular symptomatology in hyperbaria is reviewed. Most of this literature deals with vertigo as a symptom of decompression sickness in divers and caisson workers, although other symptoms (e.g. nystagmus, staggers), other influences (compression, mixed gases), and o...

Wave impacts on vertical caissons may cause breakwaters failures. This paper focuses the analysis of stability under violent wave by using a triple-coupled Fluid-Porous-Solid model. The fluid model is described Volume-Averaged Reynolds-Averaged Navier-Stokes equations in which nonlinear Forchheimer for porous medium are added to inertia terms. solid model, based DDA method an implicit DEM metho...
