Title
Satellite detected water extents in Red River Delta, as of 25 September 2024 [Viet Nam]
Description
**UNOSAT code: TC20240905VNM, GDACS ID: 1001090** Satellite detected water extents in Red River Delta, Viet Nam as of 25 September 2024 This map illustrates the floods using Sentinel-1 images acquired on 25 September 2024 at 05:58 local time. Within the analysed area of about 38,000 km², a total of about 600 km² of land appears to be affected by flood waters. Flood extent appears to have decreased by about 700 km² since 13 September 2024. Based on Worldpop spatial demographic data, about 400,000 people are exposed or living close to flooded areas as of 25 September 2024. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT). Important note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to the backscattering properties of the radar signal.
