This map illustrates satellite-detected flood waters in Quang Binh province, Viet Nam, based on a preliminary analysis of crisis Radarsat-2 data acquired on 8 & 10 October 2010. Although there are no significant indications of standing flood waters along the banks of the main Song Nan river, there are multiple areas of potentially severe local flooding mostly in the highlands to the south of Song Nan river affecting a number of locations including: the villages of Yên Lac and Tân Hóa in Tuyen Hoa district, the village of Chà Nòi in Bo Trach district; multiple small villages west of the village of Co Lung in Quang Trach district; and multiple villages along the south bank of the Song Con river in Bo Trach district. Further, at the mouth of the Song Nan river between the towns of Hoa Ninh and Ba Don, there are potentially large areas of flooding, however because of the complexity of the mixed urban, marshland and aquaculture environment in this area, there is a relatively high degree of uncertainty associated with the flood water detection and classification. This flood assessment is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
