The 2008 Bihar flood was one of the most disastrous floods in the history of Bihar, an impoverished and densely populated state in India. The Koshi embankment near the Indo-Nepal border (at Kusaha VDC, Sunsari district, Nepal) broke on 18 August 2008. The river changed course and flooded areas which had not been flooded in many decades.A Dalit watch report on the flood camps in Bihar https://web.archive.org/web/20090114192417/http://www.indiawaterportal.org/bihar/wp-content/uploads/2008/11/dalit_watch_report_on_flood_relief_camps_in_bihar.pdf 14 January 2009 The flood affected over 2.3 million people in the northern part of Bihar.http://www.ibnlive.com/news/half-of-bihar-under-water-30-lakh-suffer/72587-3.html Half of Bihar under water, 30 lakh suffer; 9 January 2008 CNN IBN 1 September 2008 https://web.archive.org/web/20080903134616/http://www.ibnlive.com/news/half-of-bihar-under-water-30-lakh-suffer/72587-3.html 3 September 2008 live
Incident
Kosi embankment
On 18 August 2008, heavy monsoon rains and poor maintenance caused a breach in the Kosi embankment. Water passed through the breach at an estimated 3675 cubic meters per second (129,800 cusecs), flooding many villages in NepalUN Office for the Coordination of Humanitarian Affairs http://reliefweb.int/report/nepal/nepal-koshi-flood-ocha-saptari-situation-report-02-oct-2008 Nepal: Koshi Flood – OCHA Saptari Situation Report, 02 Oct 2008 – Nepal | ReliefWeb Reliefweb.int 2 October 2008 and hundreds of villages in northern Bihar. The flood submerged most of the Kosi alluvial fan area, which is very fertile, with a dense agrarian population.
Background
The Kosi River's upper basin in southern Tibet and eastern Nepal drains some 60,000 km2 of mountainous terrain,http://iahs.info/redbooks/a201/iahs_201_0139.pdf Kattelman, Richard (1991) Hydrological Regime of the Sapt Kosi Basin, Nepal Iahs.info a region that tectonic forces are elevating by about 1 cm a year.http://www.terrapub.co.jp/journals/EPS/pdf/5210/52100735.pdf Xu, Liu, Song, Jiang & Shi, GPS measurements of present-day uplift in the Southern Tibet If erosion keeps pace with geologic uplift, an estimated 600 million cubic meters of sediment would be carried downstream in an average year. However, empirical measurements of the river's sediment load have yielded estimates of 100 million cubic meters annually,http://www.gisdevelopment.net/application/geology/geomorphology/geom0002.htm Srivastava, Ajay. Tectonic Zonation using Multi-Criteria Decision-Making (MCDM) Techniques: A case study of Kosi Fan, India Gisdevelopment.net indicating that the area is rising.
River gradient ranges from more than 10 meters/km for major upper tributaries in the mountains to as little as 6 cm/km as the lower Kosi nears the Ganges.Sharad Jain, Pushpendra Agarwal, Vijay Singh (2007) Hydrology and Water Resources of India. (Netherlands:Springer). As the gradient decreases on the plains, current slows and turbulence that holds sediments in suspension diminishes. Sediments settle out and are deposited on the riverbed. This process eventually raises a channel above the surrounding terrain. The river breaks out, seeking lower terrain, which it again proceeds to elevate by deposition. This creates a cone-shaped alluvial fan. The Kosi alluvial fan is one of the largest in the world, covering some 15,000 km2 and extending 180 km from the outermost foothills of the Himalayas to the Ganges river valley.http://www.geo.tu-freiberg.de/oberseminar/os07_08/ralf_dedow.pdf Dedow, Ralf. Megafans in younger orogens.
Flood waters naturally spread out over the surface of this cone. Flows over 25,000 m3/s have been measured where the Kosi exits the Himalayan foothills, enough to create a flow of water 30 km wide.http://disc.sci.gsfc.nasa.gov/geomorphology/GEO_4/GEO_PLATE_F-19.shtml Chapter 4: Plate F-19 – GES DISC Disc.sci.gsfc.nasa.gov 27 October 2009 https://web.archive.org/web/20100609135910/http://disc.sci.gsfc.nasa.gov/geomorphology/GEO_4/GEO_PLATE_F-19.shtml 9 June 2010 dead At this rate, in one week enough water would accumulate to cover the entire megafan to a depth of 1.5 meters.
Preventative flood control measures include upstream reservoirs that can also serve irrigation needs and produce hydroelectric power. However, in Nepal these are mostly in the planning stages.http://iahs.info/redbooks/a236/iahs_236_0583.pdf Nayak, Jit Narayan (1996) Sediment management of the Kosi River basin in Nepal Iahs.info The flood control measures mainly consist of downstream embankments meant to confine the river to a fixed channel. In theory, the faster flow along this channel would carry high flows away and keep sediments in suspension. 250px|thumb|Silt deposition near Kosi embankment at Navbhata, Saharsa, Bihar, India
On 18 August 2008 one of the man-made embankments failed. The river reverted from the prescribed western channel to an old channel near the centre of its alluvial fan. The river spread out widely and flooded towns, villages, and cultivated fields on the densely populated alluvial fan. Recurrent flooding on the lower Kosi contributes largely to India's history of suffering more flood deaths than any other country except Bangladesh, and has earned the Kosi the epithet "The Sorrow of Bihar".http://madhesi.wordpress.com/2008/10/29/the-sorrow-of-bihar-kosi-river The Sorrow of Bihar : Kosi River | Madhesi – United We Stand Madhesi.wordpress.com 29 October 2008

The Government of Bihar initiated Kosi Reconstruction and Rehabilitation Programme covering 30,000 affected families in Saharsa, Supaul and Madhepura district based on a pilot project implemented by ODR Collaborative, a network of organisations, supporting the Government and an owner driven reconstruction policy was formulated to support each family with Rs. 55,000 to construct their own house. After signing an agreement with the World Bank in January 2011, this programme has been upscaled to cover 100,000 families for reconstruction of hazard safe houses. The cost per house will be Rs. 55,000 ($1200) with an additional cost of Rs. 2,300 ($50) for a toilet and Rs. 5,000 ($110) for solar powered lighting. In cases where beneficiaries do not own land, the Government of Bihar will provide additional assistance of Rs. 5000 ($110) for the people to buy the land. Towards this project, the World Bank is contributing $220 million.http://www.worldbank.org.in/WBSITE/EXTERNAL/COUNTRIES/SOUTHASIAEXT/INDIAEXTN/0,,contentMDK:22806468~menuPK:50003484~pagePK:2865066~piPK:2865079~theSitePK:295584,00.html India Home Worldbank.org.in 28 March 2014 The Government of Bihar has also partnered with ODR Collaborative and UNDP to continue the social and technical facilitation and capacity building for this 'owner driven reconstruction' programme.http://www.drrprojects.net/drrp/default/download/drrpp_file.file.959a199215e44435.57422d42696861722d4b6f73695f5265636f766572792e504446.PDF Archived copy 10 May 2011 https://web.archive.org/web/20120323181126/http://www.drrprojects.net/drrp/default/download/drrpp_file.file.959a199215e44435.57422d42696861722d4b6f73695f5265636f766572792e504446.PDF 23 March 2012 dead Technical guidelines have been brought out to enable owners to build houses with various local materials including bamboo.
The rehabilitation work has been incredibly slow. Out of a total 100,000 houses to be built by the Government in the Kosi region comprising Madhepura, Saharsa and Supaul districts, only 12,500 were built till February 2014.2008 Kosi Flood Victims in Bihar still await Rehabilitation http://news.biharprabha.com/2014/02/2008-kosi-flood-victims-in-bihar-still-await-rehabilitation/ IANS news.biharprabha.com 28 February 2014
Administrative lapse
Fax messages sent by engineers at the Kosi dam warning the state government of the impending disaster went unheeded as the official authorised to respond was on leave. Consequently, many residents waiting for evacuation instructions never received warning of the flood. Nitish Mishra, Bihar's disaster management minister said that action should be taken to hold those responsible accountable.Floods have pushed Bihar back by 50 years http://www.expressindia.com/latest-news/Floods-have-pushed-Bihar-back-by-50-years/356893/ 3 September 2008 21 September 2008 dead https://web.archive.org/web/20081022082027/http://www.expressindia.com/latest-news/Floods-have-pushed-Bihar-back-by-50-years/356893/ 22 October 2008
Investigation
Bihar Government appointed a one-man inquiry commission, headed by Justice Rajesh Walia, former chief justice of Patna High Court, to probe the cause of the embankment breach. It was asked to examine all aspects related to the efforts to maintain the utility of the Kosi project since its inception in 1953 – particularly after a major landslide in 1979 pushed the Kosi towards its eastern bund – and a breach in 1991. The Commission submitted its report in March 2014.Kosi Flood 2008: Justice Walia Commission submits probe report http://news.biharprabha.com/2014/03/kosi-flood-2008-justice-walia-commission-submits-probe-report/ IANS news.biharprabha.com 28 March 2014
