Flood Waters of South Asia 2008
	International Charter Space and Major Disasters Product ID: 1264 - 12 Sep, 2008 - English GLIDE: FL-2008-000145-IND Product FOOTPRINT (LAT x LONG, WSG84 Geographic, decimal degrees) TopLeft: 28 x 82 BottomRight: 21 x 98 This map illustrates satellite detected flood water over the affected region of South Asia, covering the eastern Indian States of Bihar and Assam, as well as the whole of Bangladesh. Those areas with likely standing flood waters have been identified from Modis Aqua and Terra satellite imagery collected from 1 to 8 September 2008 at a spatial resolution of 250m. The flood water extent from August 2007 is also presented for a time comparison. Pre-flood water levels were measured for 1-10 May 2007. Of special note is the distinct area of flood water along the old Kosi river channel in the Indian state of Bihar, the result of an embankment breach in southern Nepal on 18 August 2008. Estimates of flood water area (km2) have been calculated for the affected Indian and Bangladesh administrative units (levels 1 & 2) and are presented in tabular lists. Note only units with flooded area values over 100km2 have been included. This is a preliminary analysis and has not yet been validated in the field.

Flood water detection was made with IRS (L-4) satellite imagery recorded on 24 August 2008, and a time series of ENVISAT-ASAR (IMM) radar data recorded on 22 June, 27 July & 31 August 2008. A total of 108 village / building cluster sites identified in this map extent, including the Taluk HQ town of Chhatapur are either totally or partially submerged by Koshi River flood waters as indentified with IRS satellite imagery on 24 August 2008. Additional flood analysis from ENVISAT-ASAR radar data recorded on 31 August and 5 September confirm that this area remains severely flooded. This flood detection is a preliminary analysis & has not yet been validated in the field. Map scale for A3: 1:24,000; Projection : UTM, Zone 45 North; Datum : WGS 1984.
