  Mapping Flood Risk of Nsanje District in Malawi Using Sentinel-1 Data

  By Steven V.C. Gondwe, Shital H. Shukla

  Abstract: The all-time imaging ability of SAR systems which can penetrate cloud cover and free availability of Sentinel C-Band data are very useful in deriving critical spatial information for flood disaster management in tropical areas such as Malawi. This study shows how Sentinel-1 data has been used to map flood extents by utilizing VH and VV polarizations and enhance risk mapping during the years 2015 to 2020 in Nsanje district. Multi-dated …
