sea level variations in the persian gulf, the oman sea and the north of the arabian sea have been investigated. for this purpose, 365 daily satellite images provided by the topex/poseidon (t/p) and jason-1 satellites were processed. programming in matlab software environment was also carried out for some parts of image processing. the results of this research reveal that water level fluctuation...

 Extended abstract 1- Introduction  Coastal systems are very dynamic, and their movement is relatively fast due to the collision of onshore and marine environment. The majority of the world's population is concentrated along with the coastal areas. Hormuz Strait coasts are affected by morphological variables due to the hydrodynamics of the sea and the dynamics of coastal and onshore environme...

a major part of tidal energy is usually dissipated by the interaction of tidal currents with bottom topography. gulf of oman is a marginal sea which has variable topography and its dominant tidal constituent is m2 semi-diurnal tide. in this paper, the interaction of barotropic tidal current with bottom topography is evaluated. this phenomenon causes the formation of internal tide. internal tide...

Extended abstract   1- Introduction Coastal environments are one of the most sensitive environmental systems under the influence of dominant hydrodynamic processes. Coastal changes and evolution are occurring very fast. Coastal areas are now gradually becoming known as severe natural and man-made disturbances, including sea levels rising, coastal erosion and sedimentation, and over-exploitat...
