Abstract
According to analysis of geographical location and meteorological data of Colombo port, Sri Lanka, the monsoon influences project sea area was confirmed, and the prevailing wind was NE direction in winter and SW direction in summer. The cyclone was weak when it passed through Sri Lanka island, and no serious disaster influ-ences on the project area. In this paper, the meso scale atmospheric model MM5 was adopted to reappear wind fields in 20 a from 1991 to 2010. Wave conditions at-30 m isobath around Colombo port were calculated by SWAN model using the wind field of MM5 model. The verification between model results and satellite wave values were conducted to optimize the input file of SWAN model. Yearly extreme wave height from 1991 to 2010 was obtained to calculate wave conditions in different return periods by P-Шcurve fitting method.关键词
