Satellite detected water extent in Tillabéri & Niamey Regions, Niger as of 05 October 2022

**UNOSAT code FL20221004NER**  This map illustrates satellite-detected surface waters in Tillabéri  & Niamey Regions, Niger as observed from a Sentinel-2 image acquired on 05 October 2022 at 11:27 local time. Within the extent of this map of about 40,000 km2, about 180 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters within the map extent, about 50,000 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).

Preliminary satellite-derived flood evolution assessment - 16 September 2022

**UNOSAT code FL20220808PAK, GDACS Id: 1101522**  Status: Overall decreasing flood waters observed  
Further action(s): continue monitoring  
Evolution of Cumulative Flood Impact Assessment (01 - 07 September Vs 08-14 September 2022):  
From 08 to 14 September 2022 approximately 19 million people remain potentially exposed or living close to flooded areas;  
Based on satellite observations from 01-07 September 2022 and 08-14 September 2022, the overall flood situation appears to be decreasing  with approximately 1,700 km² in Balochistan, ~Punjab 3,900 km²  and  ~850 km² in Sindh.  
The dotted line represents approximately the Line of Control in Jammu and Kashmir agreed upon by India and Pakistan. The final status of Jammu and Kashmir has not been agreed upon by the parties.

Satellite detected waters extent in El Salam & El Jabalain districts, White Nile State, Sudan as of 11 September 2022

**UNOSAT code FL20220816SDN**  This map illustrates satellite-detected surface waters in El Salan & El Jabalain districts, White Nile State as observed from a RCM-3 image acquired on 11 September 2022. Within the analyzed area of about 200 km², about 17 km² of lands appear to be flooded. Water extent appears to have decreased of about 13 km² since the 04 September 2022. Flood waters are observed in the vicinity of Alagaya refugee camp as of 11 September 2022. Kilo Arba refugee camp appears to be affected by floods as of 11 September 2022.

Satellite detected water extents between 27 and 31 March 2023 over Mozambique

**UNOSAT code TC20230221MOZ, GDACS Id: 1000961**  This map illustrates cumulative satellite-detected water using VIIRS in Mozambique between 27 to 31 March 2023. Within the cloud-free analyzed areas of about 600,000 km², a total of about 12,000 km² of land appear to be affected by flood waters. Water extent appears to have decreased by about 6,300 km2 since 21-25 March 2023.  
  
Based on Worldpop population data and the maximal flood water extent, ~650,000 people are potentially exposed or living close to flooded areas mainly located in Zambezia province with ~220,000 people and Sofala province with ~140,000 people.

Impact des inondations du 25/26 mai 2023 dans les communes de Khemisti, Bousmail et Bouharoun, Wilaya de Tipaza, Algérie

**UNOSAT code FL20230526DZA, GDACS Id: 1102025**  Cette carte illustre l’étendue ainsi que l'impact des crues subite tels qu’observés à partir de l’image satellite Sentinel-2 acquise le 27 mai 2023 à 11:36 heure locale dans les communes de Khemisti, Bousmail et Bouharoun dans la wilaya de Tipaza en Algérie. Dans la zone analysée d’environs 12,000 ha, une zone d’une soixantaine d’hectares semble avoir subi des dégâts importants. Dans cette zone, UNOSAT a identifié 2 ports endommagés, 794 structures affectées et potentiellement affectées ainsi que 31 sections de routes ayant subi des dégâts.  
Ceci est une analyse préliminaire et n'a pas encore été validée sur le terrain. Merci de bien vouloir adresser vos commentaires au Centre Satellitaire des Nations Unies (UNOSAT).

Satellite detected water extent as of 20 July 2020 over the Northeastern region of Bangladesh

**UNOSAT code: FL20200713BGD**  This map illustrates satellite-detected surface waters over Chittagong, Dhaka, Mymensingh and Sylhet Divisions of Bangladesh as observed from a Sentinel-1 image acquired on 20 July 2020 due to the current monsoon rains. Within the analyzed area of about 14,250 km2, a total of about 7,120 km2 of lands appear to be flooded. Based on WorldPop population data and the detected surface waters, about 6,700,000 people area 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 UNITAR - UNOSAT.
Important Note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to backscattering properties of the radar signal.
