Satellite-detected water extents, as of 6 November 2019 over Hiraan, Middle Shabelle and Lower Shabelle Region of Somali

**UNOSAT code: FL20191030SOM** This map illustrates the extent of surface waters detected over Jowhar District, Middle Shabelle Region located in Somalia, as detect by VIIRS-NOAA satellite between 30 October & 3 November 2019. In the analysed area, a total of about 700 km2 are likely flooded and about 70,000 people may be affected, based on WorldPop population estimates. The 10 km of roads seem to be affected. This is a preliminary analysis and has not been validated in the field yet. Please send ground feedback to UNITAR-UNOSAT.

**UNOSAT code FL20230327SOM, GDACS Id: 1101908** This map illustrates cumulative satellite-detected water using VIIRS along the Shabelle River in Somalia between 19 to 23 May 2023. Within the analysed area of about 39,000 km², about 1,400 km² of land appear to be flooded. Based on Worldpop population data and the maximum flood water coverage, at least 120,000 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, GDACS Id: 1101908** This map illustrates satellite detected surface waters Hiraan, Lower Shabelle, and Middle Shabelle Regions Somalia as observed from Sentinel-2 image acquired on 29 April 2023 at 07:06 UTC. Within the analyzed area about 12,000 km², about 600 km² of land appear to be flooded. Water extent appears to have increased by about 480km² since 19 April 2023. Based on Worldpop population data and the detected surface waters in the analyzed area 59,000 people are potentially exposed or living close 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, GDACS Id: 1101908** This map illustrates satellite-detected surface waters over southern Hiraan Region and Jowhar CIty, Middle Shabelle Region, Somalia observed from a Sentinel-2 image acquired on 24 May 2023 at 07:06 UTC. Within the analysed area of 8,600km², about 430 km² of land appear to be flooded. Based on Worldpop population data and the detected surface waters in the analysed area, at least 47,000 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).

This map illustrates satellite-detected flood water extent over Booco and Hagan areas, Hiraan region, Somalia using a Radarsat-2 image acquired on 09 May 2018. Within the extent of the map about 4,000 ha of land appear to be inundated and according to WorldPop data, ~22,000 people, live within the extent of this map about 6,500 within 100 meters distance from the flooded areas which corresponds to about 30% of population in this zone. 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 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.
