This map provides an overview of satellite detected waters along the coastline of Quang Ninh province, northern Vietnam. UNITAR-UNOSAT identified 5,986 hectares of flood affected land within the analyzed region. A total of 11 analyzed districts in the provinces of Quang Ninh and Lang Son were impacted by the floods. The district of Mong Cai in Quang Ninh province was the worst affected with 1,557 hectares of flooding, followed by Tien Yen district (951 ha) and Cam Pha district (674 ha). Approximately 2.8 kilometers of roads were possibly affected by flood waters in 9 of the 11 analyzed districts. Of this total, roughly 0.94 kilometers were identified in the district of Mong Cai. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks, and within built-up urban areas because of the special characteristics of the satellite data used. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT.
