Example of severe flooding of cultivated lands along Indus

Town of Ghaupur severely damaged by flooding from canal breachon 8-9 August, has remained submerged for over month.

The Sukkur Barrage resisted unprecedented water volume stressesand remained intact and functional providing local authorities withlimited but critical control over downstream Indus water flow.

Within the main flood water extent along the Indus there arethousands of small villages and towns that (as illustrated here insouthern Sindh province) are either submerged under water or havebecome literal islands within the Indus.

The Kotri Barrage resisted unprecedented water volume stressesand has remained intact and functional.

Severe town flooding24 August 2010

Severe urban flooding of Kot Isa Shah Town

Total collapse of two major bridges along the east and westboundlanes of the N5 approximately 700m to the north-east of the townSura Khel. All highway traffic diverted along an access road whichitself at risk of flooding. The east-west railroad lines unaffected andoperational.

Destroyed Bridge in LowerDir 14 August 2010

70 meters of main bridge south of Chakdara town in Lower Dirdistrict, Khyber Pakhtunkhwa destoryed by flash flooding.

Jacobabad remained partially flooded in northern and easternsections of the city for over two weeks; completely encircled byflood waters, leaving no functional land transport routes for aid orevacuation.

Within Sukkur city, 12 IDP camps with several hundred individualtents were identified as open from satellite imagery recorded on 29August 2010

ANALYSIS BACKGROUND:UNOSAT provided emergency response maps to thehumanitarian community with the support of theInternational Charter Space and Major Disasters incollaboration with several partners. This product is issuedin support of the Early Recovery Cluster and to facilitatethe work of the UN in the damage assessment and postdisaster phase. UNOSAT, the World Bank (GFDRR) andthe EC Joint Research Centre (JRC) have a standingcollaboration engagement for the use of GIS andsatellite analysis in support of damage assessment.ANALYSIS SUMMARY:This map presents a comprehensive overview of themaximum flood water extent across the affectedprovinces in Pakistan as detected by a constellation ofsatellite sensors throughout the course of thiscatastrophic disaster from 28 July to 7 September 2010.Flood waters depicted on the map have been symbolizedwith two classes, the first and primary class (shown inred), represents the maximum water extent across theaffected provinces, as identified with a very high degreeof confidence; the second class (shown in orange),represents potential flood waters which were identifiedwith a moderate to low degree of confidence. Insetsatellite images over selected locations across theaffected region provide detailed examples of the type ofdamages and other flood related issues that will need tobe addressed during the early recovery andreconstruction phases. Further, a spatial analysisconducted with satellite-derived flood data provided apreliminary estimate of the potential number of villages,towns, infrastructure sites as well as the length of roadsand railway tracks directly affected by the flooding.These results have been quantified by administrativeprovince (see included table). Across the whole of theflood affected region, it has been estimated that over7,490 villages, 135 towns/cities and 190 health facilities

were identified as potentially directly affected by theflood waters, the majority of villages completelyinundated or surrounded by flood waters without openland evacuation routes. Over 5,000 km of primary orsecondary roads were likely submerged along with 400km of railway tracks and 400 bridges. Please note thatthe numbers of affected locations presented in this mapand associated table likely represent absolute minimumestimates for the area assessed; because of limitations inavailable settlement and transportation datasets it iscertain that the numbers of affected villages, towns andaffected infrastructure / transportation lines aresignificantly underestimated. This disaster analysis wasconducted with satellite imagery provided through theInternational Space Charter as well as from ESA, NASAand USGS.CALCULATING THE MAXIMUM FLOOD EXTENTThe estimated total surface area of all satellite-detectedflood waters during this event was 37,280km2 based oncumulative analysis from 28 July to 16 September 2010.This estimate includes both water classes shown in themap and has been controlled for the normal, pre-crisiswater extent of major rivers, lakes and reservoir waterbodies using the best available hydrological datasets.Because of the limited duration of the reported flashfloods in the northern provinces of Pakistan (especiallyKhyber Pakhtunkhwa), as well as limitations of thesatellite sensors used for this analysis, it is likely that thetotal extent of flood waters have been underestimatedby potentially upwards of several hundred squarekilometres. Nevertheless, the total impact of thisprobable underestimation is essentially negligible whencalculating the overall accuracy and completeness of theflood water area estimation for the whole of Pakistan.Based on these results, it is estimated that approximately4.5% of the surface area of Pakistan was directly floodedduring the course of this event.

Collapse of N5 highway2 August 2010

A significant majority of buildings in the town of Nawe Kili werepartially submerged under flood water from the Kabul River and arelikely severely damaged or destroyed. Almost all interior local roadsimpassable.
