Abstract

Kien Giang is one of the provinces with great potential for sustainable marine aquaculture development in Vietnam and the marine dynamics is an important factor in choosing an appropriate mariculture area. This paper presents the results of research, analysis and assessment of marine dynamics in the sea area of Kien Giang province through the process based modeling of the MIKE21/3FM. The results of the study indicated that, in the study area of ​​Kien Giang sea area, irregular diurnal waves play the main role in the tidal regime with an average tidal oscillation of approximately 1m. In general, the flow speed in the study area is relatively small, averaging 20-35cm/s, except for some sea areas of An Thoi and Ganh Dau. Unlike some other sea areas in Vietnam, the wave field regime is weak with wave height of about 0.3m-0.7m in Kien Giang sea waters in the northeast monsoon, which is smaller than in the southwest monsoon with the average wave height of around 0.5m-1.0m. From the results of marine dynamics, the article also proposes a number of suitable potential mariculture areas in Kien Giang sea waters, of which two areas with great potential are Phu Quoc island and the Nam Du archipelago.
