Fig. 2: Comparison of flood extent maps for Ethiopia.
From: Mapping global floods with 10 years of satellite radar data
Comparison of flood extent mappings over Ethiopia from multiple satellite sources. Blue areas show SAR flood detections from our deep-learning model (2014–2024), while orange areas represent historical flood extent from MODIS and Landsat optical and near-infrared imagery (1984–2021). Green areas indicate agreement between SAR and optical datasets. The map reveals both consistencies and complementarity between detection methods, with notable flood-prone areas identified along the Shabelle, Ganale, and Awash rivers. Darker gray areas indicate regions where SAR flood detection may be unreliable due to terrain or land cover characteristics.
