A reshaping berm breakwater is a type of rubble mound breakwater in which, its seaward slope is allowed to reshape under wave attacks. There are some key parameters in the reshaped seaward profiles, which can schematize the reshaped profile of a berm breakwater. A total of 412 test results was used directly to cover the impact of sea state conditions and structural parameters on these reshaping...

Autonomous Underwater Vehicles (AUVs) are suitable for underwater observation, since they can swim freely without an umbilical cable. This paper proposes a robust navigation method for AUVs operating around artificial structures such as piers, quays and breakwaters. This method consists of a State Estimator and a Guidance System, enabling localization in the configuration map as well as followi...

A hybrid system integrating a power take-off (PTO) into floating breakwater is promising candidate for both shoreline protection and commercial wave energy extraction. Although geometric asymmetry important to such PTO-integrated breakwaters, its role in conversion efficiency attenuation poorly understood. In this study, two-dimensional semi-analytical model dealing with floats arbitrary bottom...

This paper is presented to develop the hydrodynamic performance of double-row floating breakwater (FBW) by changing cross-sectional geometry in high wave periods. The ANSYS-AQWA software employed for present calculations, which a potential-based boundary element method (BEM). rectangular moored pontoons single- and types are selected, results transmission coefficient response amplitude operator...

Surface gravity wave interaction with a semi-infinite floating elastic plate in the presence of multiple undulations has been studied under assumption linearized water theory and small amplitude structural response. The is modeled using Euler-Bernoulli beam equation, whilst are categorized as an array submerged trenches or breakwaters. numerical solution obtained finite depth boundary element m...
