Breaker wind waves energy at Iraqi coastline.

Abstract

Abstract Hydrographical survey were carried out for four cruises during the period 22 March to 9 May, 2007 by Marine Science Center team in the Iraqi marine water. By using the prediction method of Karsten , the breaker wave height root mean square Hrms was computed as a function of water depth and the breaker wave energy was computed as a function of Hrms in Mean Higher High Water (MHHW) for 45 points at the Iraqi coastline in the north of the Arabian Gulf. The results showed that the gradient of Iraqi coast at the study area was flat and the predominant type of breaker waves was spilling.The highest value of the energy of these waves was 1214,258992 J/m2 at point no. 45. The highest breaker wave height root mean square Hrms was 0.981 m at the same point.
