This map illustrates satellite-detected flood waters over the affected regions of Zambia as of 8 & 20 March 2009. Flooded areas have been sorted into 3 classes: Flood waters detected only on the 8th (indicating a decrease in flood waters); only on the 20th (indicating a rise in flood waters); and on both the 8th and 20th of March 2009 (indicating stable flood water levels). The rainfall estimate was derived from the Tropical Rainfall Monitoring Mission (TRMM) precipitation dataset at a spatial resolution of approximately 25km for this region. This flood detection is a preliminary analysis & has not yet been validated in the field. Map scale for A3: 1:850,000; Projection - UTM Zone 34 South WGS 1984.
