Extensões de água superficias detectadas por satélite na Província de Zambezia Moçambique, no dia 15 de março de 2022

**UNOSAT code: TC20220311MOZ** Este mapa ilustra água superficias detectadas por satélite nos distritos de Mossuril, Mogincual e Liúpo, Província de Nampula em Moçambique, no dia 13 de março, 2022, as 17:44 hora local. Dentro da área analisada de cerca de 14,000 km2, um total de 110 km2 aparece inundada. Baseado nos dados de população do Worldpop e na águas superficiais, cerca de 12,000 pessoas estão potencialmente expostos ou vivem perto das áreas inundadas. Esto sao análises preliminar e ainda não foram verificados no terreno. Por favor, envie comentários United Nations Satellite Centre (UNOSAT). Nota importante: Análises de inundaçãoes a partir de imagens radar podem subestimar a presença de águas acumuladas em áreas construídas e áreas de vegetação densa devido às propriedades de retrodifusão do sinal radar.

**UNOSAT code: TC20220311MOZ** This map illustrates satellite-detected surface waters in Maganja da Costa, Moaquival and Namacurra Districts, Nampula Province, Mozambique as observed from a RCM-1 image acquired on 15 March 2022 at 05:10 local time. Within the analyzed area of about 1500 km2, about 237 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 22,600 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). 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.

**UNOSAT code: FL20250121MOZ** Este mapa ilustra a água detectada por satélite nos Distritos de Mossuril e Ilha de Moçambique, Província de Nampula, usando imagens satélite tirada no dia 18 de janeiro de 2025 às 09:34, horário local. Dentro da área analisada de aproximadamente 4.600 km², estima-se que 60 km² de terra tenham sido afetados pelas águas das enchentes. Com base nos dados demográficos espaciais do WorldPop, aproximadamente 9.000 pessoas estão expostas ou morando perto das áreas inundadas. Essa é uma análise preliminar e ainda não foi validada em campo. Envie comentários sobre o solo para o Centro de Satélites das Nações Unidas (UNOSAT).

**UNOSAT code TC20230221MOZ, GDACS Id: 1000961** This map illustrates cumulative satellite-detected water using VIIRS in Mozambique between 21 to 25 March 2023. Within the cloud free analyzed areas of about 620,000 km², a total of about 18,300 km² of lands appear to be affected with flood waters. Water extent appears to have decreased of about 2,700 km2 since the 15-19 March 2023. Based on Worldpop population data and the maximal flood water extent, ~1,300,000 people are potentially exposed or living close to flooded areas mainly located in Zambezia province with ~480,000 people, Nampula province with ~210,000 people and Sofala province with ~ 210,000 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 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. This preliminary analysis has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).

**UNOSAT code: TC20220124MOZ** This map illustrates satellite-detected surface waters in Malawi and Mozambique as observed from a Sentinel-1 image acquired on 02 February 2022 at 10:04 local time. The flood analysis were carried out by using an automated analysis with Artificial Intelligence based methods. Within the analyzed area of about 145,978 km2, about 859 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters in the analyzed area, the potentially exposed population is mainly located in the districts of Mutarara, Cidade de Quelim and Morrumbala with respectively ~ 33,000 people, ~ 11,000 people, and with ~16,600 people. 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.
