Satellite detected waters extents, as of 23 October 2019 over Unity, Jonglei and Lakes State of South Sudan

**UNOSAT code: FL20211015SSD** This map illustrates cumulative satellite-detected water using VIRRS in South Sudan between 09 to 13 October 2021 and 26 to 30 September 2021. Within the analyzed extent not covered by clouds, a total of about 37,000 km2 appear to be flooded. Based on Worldpop population data and the detected surface water, about 1,000,000 people are exposed or living close to flooded area. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).

**UNOSAT code: FL20211015SSD** This map illustrates cumulative satellite-detected water using VIIRS in South Sudan between 19 to 23 November 2021 compared with the period between 03 to 07 November 2021. Within the cloud free analyzed areas of about 630,000 km2, a total of about 33,000 km2 of lands appear to be affected with flood waters. Water extent appears to have decreased of about 660 km2 since the period between 03 to 07 November 2021. Based on Worldpop population data and the detected surface waters, ~880,000 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 the United Nations Satellite Centre (UNOSAT).

**UNOSAT code: FL20190815SDN** This map illustrates satellite-detected surface water in Sennar State, Sudan as observed from SPOT-6 imagery acquired on 28 August 2019. Within the analysed extent of about 700 km2, a total about 23 km2 of lands appear to be flooded as of 28 August 2019. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT.

**UNOSAT code: FL20220119SSD** This map illustrates cumulative satellite-detected water using VIIRS in South Sudan between 23 to 27 Feb. 2022 compared with the period from 11 to 15 Feb. 2022. Within the cloud free analyzed areas of about 629,000 km2, a total of about 21,200 km2 of lands appear to be affected with flood waters. Water extent appears to have decreased about 8,000 km2 since the period between 11 to 15 Feb. 2022. Based on Worldpop population data and the maximal flood water coverage, ~522,000 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 the United Nations Satellite Centre (UNOSAT).
