Changing Flood Water Levels in Northern Senegal and Southern Mauritania
	Product ID: 1381 - 30 Sep, 2009 - English GLIDE: FL-2009-000170-MRT Product FOOTPRINT (LAT x LONG, WSG84 Geographic, decimal degrees) TopLeft: 17 x -16.5 BottomRight: 14.5 x -12 This map illustrates satellite-detected changes in the flood water levels in northern Senegal and southern Mauritania, as based on change detection methods using multiple MODIS Aqua & Terra data acquired over the period of 29 August - 21 September 2009. There are 3 water classes represented in the map: Flood water present throughout 29 August - 21 September 2009 (yellow) flood water present durring 29 August - 07 September (orange) flood water present durring 19 - 21 September (red). This data is a conservative estimate of the event and is a preliminary analysis which has not yet been validated in the field. Source(s): Satellite Data ....................

It is likely that standing water bodies located along narrow streets have been potentially underestimated. This flood assessment is a preliminary analysis & has not yet been validated in the field.

Pre-crisis Radasat-1 from 6 September 1999 and was also used. The primary locations of flood waters affecting the city are located in the northern and eastern edge of the urban zone. Please note there is an associated degree of uncertainly for this flood assessment resulting from the dense urban environment and the lack of archived radar data of corresponding sensor characteristics. It is likely that standing water bodies located along narrow streets have been potentially underestimated. This flood assessment is a preliminary analysis & has not yet been validated in the field.

	International Charter Space and Major Disasters Product ID: 987 - 20 Sep, 2007 - English GLIDE: FL-2007-000153-GHA Product FOOTPRINT (LAT x LONG, WSG84 Geographic, decimal degrees) TopLeft: 18 x -17 BottomRight: 14 x -11 This map illustrates the estimated population density within 5km of satellite detected flood water in Mauritania and Senegal. Total population figures have also been estimated by province and district admin. units (levels 1 & 2). Flood water analysis was made using MODIS Terra data recorded from 12-15 September 2007. Additional pre-flood MODIS terra data from May 2007 (depicted in blue) was used in this analysis. This flood detection is a preliminary analysis & has not yet been validated in the field.
