The method includes two stages. The first stage is called the raw stage. In this stage based on the history of oil pollution at the Vietnamese coast and oil pollution footprint detected by remote sensing technique numerical computation of wind and flow field in the sea was carried out. With the obtained wind and flow fields reversed analysis was carried out to have a raw determination of possible sources of oil pollution. The second stage is called the refined stage. In this stage based on the results of the raw stage the location of oil source was corrected by assuming different oil slick scenarios locations of oil source discharge amount and discharge time . Then numerical computations were carried out again to determine the transport and weathering of oil after being discharged from the source. The oil slick scenario which best fit the history of oil pollution and oil slick footprint will be selected as the oil pollution source. 1. Introduction Recently oil pollution has become an increasing environmental problem for the Vietnamese coast and sea. The area with oil pollution is expanding while the degree of pollution is increasing. During recent ten years there are more than ten oil pollution events which caused great environmental consequences to the estuarine and nearshore areas of Vietnam. Typical oil pollution events are listed bellows. On October 3 1994 the Neptune Aries Singapore collided with pier at Cat Lai port caused the slick of tons of oil. On September 7 2001 the Formosa One Liberia collided with other ship at Ganh Rai Bay caused the slick of 900m3 of oil. On February 6 2002 the Bach Dang Giang Vietnam collided with submerged rock in Hai Phong coastal water caused the slick of
