Situation Update 5 - Sujawal Town flooded in Major outflow from Indus, Thatta District

This is the fifth situational update on the status of flood waters between the cities of Thatta and Sujawal, in Thatta district based on an analysis of ENVISAT ASAR satellite data recorded 1 September 2010 at 5:33 UTC. Over the last 48 hours the Town of Sujawal has likely been severely flooded, with no functional road access. This was the direct result of a major water outflow event from the eastern bank of the Indus River on 28 August 2010, advancing over 45km to the south-east as of 1 September. The town of Jati is under imminent threat of flooding within the next 24 hours. The current direction of this outflow should take it into the delta, which could act to lessen the severity of flooding further south in Thatta District along the Indus channel to the Arabian Sea. Flood waters immediately east of Thatta city have remained relatively stable over the last 72 hours and have not advanced closer to the city. The town of Chuhar Jamali is also at high flood risk. This situational analysis is based on a rapid analysis of current satellite data available and will be revised and updated as new data becomes available; this analysis has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT. Map scale for A4: 1:350,000; Projection: UTM Zone 42N - WGS-84.
