A wave is an energy that can propagate with a medium; the propagation of moves respect to time by carrying velocity per unit time. Sea waves are one propagating problems broken down produce relatively inhomogeneous minimum amplitude and speed sea waves, which have their own difficulties in solving them numerically. This study aims analyze stability on submerged breakwaters. research will approx...
Abstract The hydrodynamic characteristics of a Bragg breakwater with triple vertical plates in monochromatic regular waves are experimentally studied. two spacings between the every adjacent denoted by S 1 and 2 respectively which both wide enough for necessary reflection, is equal or unequal to . A series experiments carried out wave flume equipped piston-type generator, performance analysed v...
During the design of a shoreline electrode station for High-Voltage Direct Current (HVDC) interconnections, location electrodes plays critical part, especially in development near-electric field. The basic structure is their linear placement, form successive frames, parallel to longitudinal axis breakwater, as proposed by CIGRE and implemented existing projects. However, this arrangement requir...
Extreme waves, called rogue waves or freak usually occur unexpectedly and with very large wave heights. In recent years, extreme were reported not only in deep ocean waters but also shallow waters, which threaten the safety intactness of coastal regions. To prevent infrastructures communities from devastating power surges many defense structures built along coastline, i.e., submerged permeable ...
بندپایان در حدود 75درصد انواع جانوران از جمله کنه های ایکسودیده ، بزرگترین شاخه جانوری می باشند (یخچالی و حاجی حسن زاده زرزای, 1383). خانواده کنه های سخت در زیر راسته متااستیگماتا و راسته کنه سانان (آکارینا) از شاخه بندپایان قرار دارند (wall and shearer, 2001). تاکنون 650 گونه و در حدود 13 جنس در 5 زیرخانواده از آنها گزارش گردیده است (wall and shearer, 1997; wall and shearer, 2001 ). به طوری که...
