from the 22 January 2017 image 20°58'0"S This map illustrates satellite-detected flood waters over Save River in Mozambique as observed from the Sentinel-1 image acquired on 10 January 2017 and Machanga Radarsat-2 image acquired on 22 January 2017. An Expansion of the Save River as observed increase of surface water extent was observed in the from the 22 January 2017 image 22 January 2017 image compared to the 10 January 2017 image including the zones along the Save river and several areas along this river were inundated. The surface waters evolution is about 60% from the 10 Primary School Matasse January to the 22 January 2017. 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 Nova Mambone 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 - Riverbank Mussanga UNOSAT. 21°0'0"S
