Abstract :

Observation and consideration of waves’ characteristics in coastal zone is one of the most importanttopics in the field of costal engineering. Chabahar area has attracted attentions due to its strategiclocation in transportation developments of the region with other parts of the world, especially FarEast. This study looked at the data gathered from buoy during summer, and winter of 1998 to 2000and registered wind analysis during 1998 until 2003, waves and wind rose of the region. Based on thisinformation, it is shown that this region mostly has instabilities in its surface layers and most of thetime, duration-limited wave growth conditions dominated on waves. The similar model of wave,considers the relationship between non-dimensional parameters. The main objective of this research iscalculation and estimation of non-dimensional energy, frequency, fetch and duration of wind wavesand the relations between these parameters for Chabahar coast.
