This map illustrates satellite-detected flood waters over the affected districts of Chibuto, Chowke & Xai-Xai of Gaza province and Manhic, Magude & Bilene of Maputo province, Mozambique. Flood waters were identified through an analysis of Radarsat-2 satellite data recorded on 30 January 2011 with a medium degree of confidence. The pre-flood water extent was extracted from Radarsat-1 data collected on 3 February 2008. This flood detection is a preliminary analysis & has not yet been validated in the field. It is possible that flood waters have been significantly underestimated in certain vegetated areas along the Limpopo and Incomati rivers because of water signature confusion in the radar data. Flood waters shown in this map thus likely represent minimum estimates. The rainfall data was derived from the Tropical Rainfall Monitoring Mission (TRMM) precipitation dataset at a spatial resolution of approximately 25km for this region. It is possible that precipitation levels may have been underestimated for local areas, and is not a substitute for ground station measurements.
