This paper investigates the wave transmission through artificial reefs utilised as low-crested breakwaters to mitigate coastal erosion and reduce energy. The study utilises DualSPHysics smoothed particle hydrodynamics (SPH) solver evaluate effectiveness of such structures. Wave coefficients were computed for various reef configurations conditions. Results indicate that shifted configuration pro...

the nonlinear discrete crack modeling of Shahid Rajaee thin arch dam is considered. The interface elements are positioned such that certain potential separated blocks can form possible failure mechanisms. The dynamic stability of theses blocks are investigated by a special finite element program "MAP-73" which its nonlinear algorithm and interface elements formulation are presented.

nowadays, the application of floating breakwaters in small or recreational harbors has found more popularity. these types of breakwaters are more flexible in terms of design, configuration and especially installation compared with fixed breakwaters. in the current study, the performance of floating breakwater (fbs) under regular waves was studied using the physical modeling method. for the mode...

The necessity to implement solutions that guarantee the protection and recovery of coastal area makes submerged breakwater employment is evaluated as a viable variant application because these works contribute conservation natural aesthetic conditions beaches, which part tourist product marketed. However, parameters intervene in their functional design are not very well established, propitiatin...

In this paper, we investigate the wave damping mechanism by sinusoidal submerged breakwater using a half-linear Shallow Water Equations (SWE). We solve equations analytically multi-scale expansion method to obtain elevation profile over with specific height and length. Then, get information about how much caused breakwater, derived analytical solution reflection transmission coefficient. Furthe...

Flood is natural phenomenon that cannot becompletelycontrolled by man. Floodis a global problem. Even urban areas whichhave good development planning and drainage systemsare susceptible to floods. Flooding in area usually associated with poor system maintenance, failure plan system, not planned properly,and climate change factors. Typically,engineering measuresare meanttoreduce severity of floo...

In this article, failure and fracture mechanisms in an aluminum alloy (which has been used in diesel internal combustion engines), with and without ceramic thermal barrier coatings, have been investigated under isothermal and non-isothermal fatigue loadings. In this research, the base material is an aluminum-silicon-magnesium alloy and the thermal barrier coating includes a metallic bond coat l...

Abstract This study develops a new numerical simulation model for rubble mound failure prediction caused by piping destruction under seepage flows. The has been pointed out as significant cause of breakwater during tsunamis. Once boiling and heaving occur on the surface, suddenly propagates in opposite direction flow. For prediction, coupled fluid-soil-structure simulator is developed combining...
