Volume 4, Issue 1 , February 2014, Pages 1-6

  The use of acoustic waves in researches related to sea water is of most importance among scientists recently. Since these waves are the only waves, transmitted in water with lowest attenuation and high speed, they can be used in many scientific fields. The main goal of this research is to better understand ...  Read More

Numerical modelling of induced rip currents by discontinuous submerged breakwaters

mohammad javad ketabdari; m. BarzegarPaiinlamouki

Volume 4, Issue 1 , February 2014, Pages 15-24

  Submerged breakwaters are one of the shore protective structures. Any discontinuity in these breakwaters causes changes on current parameters including speed and water surface profile. In this paper, discontinuous submerged breakwaters were modelled to investigate the changes in the wave and flow pattern.To ...  Read More
