Satellite Detected Water Extent Over Province 1 And 2

Disclaimer:

  • Flood analysis from SAR Sentinel-1 images may significantly underestimate the presence of standing waters in built-up and/or densely vegetated areas due to backscattering of the radar.
  • Flood extraction was calculated using a deep learning model. Details about the model and training set can be found here: https://www.mdpi.com/791202
  • WorldPop calculation may significantly overestimate the population affected by floods in urban areas.
  • All statistics are computed based on WorldPop and cover only over Nepal.
