Satellite detected water and landslide/mudflow extents in Brazzaville Department, Republic of Congo as of 8 February 2024

**UNOSAT code: FL20240102COG** This map illustrates satellite-detected surface waters and landslides/mudflow extent in Brazzaville and Pool Departments, Republic of Congo, as observed from a Sentinel-2 image acquired on 28 December 2023, at 10:21 local time. Within the analysed area of 30,000 ha, approximately 190 ha of landslide scars/mudflow extent are observed and about 230 ha of land appear to be flooded. Based on Worldpop population data, the detected surface waters and the landslide scar/mudflow extent, about 15,000 people are potentially exposed or living close to landslide and flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please provide ground feedback to the United Nations Satellite Centre (UNOSAT).

**UNOSAT code: FL20231229COD** This map illustrates satellite-detected surface waters and landslides in Kinshasa Province, Democratic Republic of The Congo, as observed from a Sentinel-2 image acquired on 28 December 2023, at 10:21 local time. Within the analysed area of 44,000 ha, approximately 3 ha of landslide scars are observed and about 460 ha of land appear to be flooded. Based on Worldpop population data, the detected surface waters and the landslide scar extent, about 25,000 people are potentially exposed or living close to landslide and flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please provide ground feedback to the United Nations Satellite Centre (UNOSAT).

**UNOSAT code: FL20231229COD** This map illustrates satellite-detected surface waters and landslide location in Kinshasa Province, Democratic Republic of The Congo, as observed from a WorldView-3 image acquired on 13 January 2024, at 10:36 local time. Within the analysed area of 130km2, approximately 4 km2 of land appear to be flooded and a landslide location observed. Within the analysed area 9,352 buildings are identified as potentially affected by the floods and landslide. 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: FL20211208COG** This map illustrates cumulative satellite-detected water using VIIRS in Republic of Congo between 03 to 07 December 2021 compared with the period between 26 to 30 November 2021. Within the cloud free analyzed areas of about 335,000 km2, a total of about 3,500 km2 of lands appear to be affected with flood waters. Water extent appears to have decreased of about 300 km2 since the period between 26 to 30 November 2021. Based on HRSL population data and the detected surface waters, the potentially exposed population of ~190,000 people is mainly located in department of Likouala with ~ 94,000 people, Brazzaville with ~ 70,000 people and Plateaux with ~10,000 people. 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: FL20240102COG** This map illustrates cumulative satellite-detected minimum floodwater using VIIRS in Republic of Congo between 29 December 2023 and 2 January 2024. Within the cloud free analysed area of about 330,000 km2, a total of about 1,000 km2 of lands appear to be affected with flood waters. Based on Worldpop population data and the minimum flood water coverage, ~114,000 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 provide ground feedback to the United Nations Satellite Centre (UNOSAT). Important note: Minimum floodwater extent indicates the portion of the pixel (375m) covered by 80 to 100% of flood water.

**UNOSAT code FL20221019TCD** This map illustrates satellite-detected surface waters in N'Djamena Department, N'Djamena Region, Chad as observed from a WorldView-2 image acquired on 24 October 2022 at 10:38 local time. Within the analyzed area of about 300 km2, about 38 km2 of lands appear to be flooded and 14,799 structures are potentially affected by the floods. Based on Worldpop population data and the detected surface waters, about 154,000 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).
