Satellite Detected Water Over Shabelle & Afder Zones, Ethiopia

This map illustrates satellite-detected flood water extent in Somali Region, Ethiopia. The analysis was conducted by analysing a Sentinel-1 image acquired on the 7 May 2018. As observed from the satellite radar image, a total of 11,329 ha of land were inundated in the area of interest. By using WorldPop data, we estimate that at least 8,800 people are potentially affected or living close to the potentially flooded area. This corresponds to about 6% of the population living in the area of interest. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks and within built-up urban areas because of the special characteristics of the satellite data used. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR UNOSAT.

This map illustrates satellite-detected flood water extent over the district of Baardheere (Gedo Region), the districts of Saakow and Bu'aale (Middle Juba region) and the district of Diinsor (Bay region), Somalia using a Radarsat-2 image acquired on 09 May 2018. As observed from the satellite radar image, a total of 61,000 ha of land were inundated in the area of interest. By using WordPop data, we estimate that at least 100,000 people are potentially affected or living close to the potentially flood area. This correspond about 35% of the population living in the area of interest. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks and within built-up urban areas because of the special characteristics of the satellite data used. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR UNOSAT.

**UNOSAT code FL20230327SOM, GDACS Id: 1101908** This map illustrates satellite-detected surface waters in Shabelle Zone, Somali Region of Ethiopia and Beledweyne and Northern Bulo Burto District, Hiraan Region of Somalia as observed from a Sentinel-2 image acquired on 14 May 2023 at 07:28 UTC. Within the analyzed area of about 8,000 km², about 500 km² of land appear to be flooded. Water extent appears to have increased by about 300 km² since 29 April 2023. Based on Worldpop population data and the detected surface waters in the analyzed area, about 29,700 people are potentially exposed or living close to flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to United Nations Satellite Centre (UNOSAT).

**UNOSAT code FL20230327SOM** This map illustrates satellite-detected surface waters in Shabelle Zone, Somali Region, Ethiopia as observed from a Sentinel-2 image acquired on 2 April 2023 at 07:38 UTC. Within the analyzed area of about 22,000 km², about 180 km² of land appear to be flooded. Water extent appears to have decreased by about 230 km² since 28 March 2023. Based on Worldpop population data and the detected surface waters in the analyzed area, 19,000 people are potentially exposed or living close to flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to United Nations Satellite Centre (UNOSAT).

**UNOSAT code FL20230327SOM** This map illustrates satellite-detected surface waters in Shabelle Zone, Somali Region of Ethiopia and Beledweyne District, Hiraan Region of Somalia as observed from a Sentinel-2 image acquired on 29 April 2023 at 07:06 UTC. Within the analyzed area of about 5,300 km², about 180 km² of land appear to be flooded. Water extent appears to have increased by about 60 km² since 19 April 2023. Based on Worldpop population data and the detected surface waters in the analyzed area, 7,500 people are potentially exposed or living close to flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to United Nations Satellite Centre (UNOSAT).

This map illustrates satellite-detected flood water extent in the district of Jilib, Middle Juba, Somalia. The analysis was conducted analyzing Sentinel-1 images acquired on the 1 May 2018. As observed from the satellite imagery, a total of 92,000 ha of land were inundated in the area of interest. The most affected districts are Saakow, with almost 38,000 ha of flooded land and southern Diinsoor, with almost 27,000 ha. At least 20 settlements are potentially located within the flooded area. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks and within built-up urban areas because of the special characteristics of the satellite data used. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR UNOSAT.
