This map presents a preliminary analysis of probable flood-affected villages, towns and infrastructure along the Indus River in Sindh and Balochistan Provinces, and is based on satellite imagery covering the period from 5 to 18 August 2010. Villages, towns, infrastructure sites as well as the length of roads and railway tracks within the detected flood water extent have been identified and quantified by administrative district (see included table). In Balochistan Province, over 110 villages, 5 towns and 8 health facilities were identified as probably severely affected by the flood waters, the majority completely inundated or surrounded by flood waters without open land evacuation routes. Over 170 km of primary or secondary roads are likely submerged along with 10 km of railway tracks and 5 bridges. In Sindh Province, over 1,120 villages, 28 towns/cities and 34 health facilities were identified as probably severely affected by the flood waters, the majority completely inundated or surrounded by flood waters without open land evacuation routes. Over 950 km of primary or secondary roads are likely submerged along with 120 km of railway tracks and 23 bridges. In addition to the overall expansion of the flood water extent, there are specific locations of rapid flood water outflow to the west which have advanced over 120km from the original suspected canal breach along a canal line north of Sukkur barrage, inundating a total of 2,670 km2 of land. This flood water outflow event continues to advance at a rate of approximately 10-25km per day and represents a significant threat to potentially hundreds of currently unaffected villages along the boundary between Sindh and Balochistan province. The approximate direction and relative size of these flood outflows have been identified. Please note that the numbers of affected locations presented in this map and associated table represent absolute minimum estimates for the area assessed; because of limitations in available settlement and transportation datasets it is certain that the numbers of affected villages, towns and affected infrastructure / transportation lines are significantly underestimated. This analysis is based on satellite data collected by MODIS sensors from 8-18 August, JAXA PALSAR data on 5 August, and Radarsat-2 data on 5 August 2010. Please note that detected water bodies likely reflect an underestimation of all flood-affected areas within the map extent. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT. Map scale for A3: 1:500,000: Projection : UTM Zone 42N; Datum : WGS-84.
