This map presents a chronological view of the estimated changes in flood water affected areas in Mopeia District, Zambezia Province from 4 to 20 January 2008. Flood water has been detected and measured using the MODIS Terra & Aqua satellite imagery. The spatial extent of flood water in Mopeia has been classified by date to help illustrate the dramatic increase in flood-affected areas from 322 km2 on 4 January 2008 to over 1,250 km2 on 20 January 2008. The map extent illustrates the area of greatest flood water expansion north of the Zambezi river, however there are smaller areas of rising flood water in Mopeia that are not visible within this map. All Estimates for flooded areas have been calculated in km2, represent approximate values only. This flood detection is a preliminary analysis & has not yet been validated in the field.
