Fig. 3: Detailed flood detection comparison in key Ethiopian regions.
From: Mapping global floods with 10 years of satellite radar data
Comparison of flood extent mappings in two flood-prone regions of Ethiopia: a Semera in the Awash River Basin and b Dolo Ado along the Ganale River. Blue areas show Sentinel-1 SAR flood detections from our deep-learning model (2014–2024), orange areas represent MODIS/Landsat flood extent (1984–2021), and green indicates agreement between datasets. Both regions demonstrate increased flood detection capabilities from our method, with significant amounts of flooding detected only by our model (blue). Darker gray areas indicate regions where flood detection may be unreliable.
