This map illustrates satellite-detected flood waters along the Limpopo River in the Guija and Chokwe districts of Gaza Province, Mozambique, as detected by SPOT-5 imagery acquired the 24 January 2013. This analysis indicates a considerable flood extent due to swelling of the Limpopo River as waters flow towards the coast, a conclusion also supported by analysis of MODIS satellite imagery from 24 January 2013. There has been a dramatic increase of flood waters from the 23rd to 24th January 2013. Multiple villages and the city of Chokwe are inundated by flood waters along the river. Flood waters have begun streaming south of Chokwe city into surrounding agricultural areas and towns,with similar conditions on the eastern bank of the Limpopo River in the analysis area. Large sections of road and railroad are also potentially affected. It is likely that flood waters have been systematically underestimated in highly vegetated areas along main river banks, and within built-up urban areas due to the characteristics of the satellite data used. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR /UNOSAT.
