The document summarizes water-induced disaster management in Nepal by the Department of Water Induced Disaster Prevention (DWIDP). It outlines the types of water disasters that frequently affect Nepal, including floods, landslides, and debris flows. It then discusses DWIDP's role in managing these disasters through both structural measures like river training and dikes, and non-structural measures like public awareness campaigns, training programs, and emergency relief efforts. The document concludes by noting several ongoing issues around water disaster management in Nepal like unplanned development and the need to strengthen preparedness and community awareness.
Dwidp presentation 1
- 1. Plan of action of Department of Water Induced Disaster Prevention in Disaster Risk Reduction R.P Adhikary, SDE, DWIDP
- 2. Outline of Presentation Background of Country Types of Water Induced Disaster in Nepal Average annual losses by Water Induced Disaster Management of Water Induced Disaster Role and activities of DWIDP Issues of Water Induced Disaster Management
- 3. Background Nepal posses more than 6,000 rivers draining about 225 BMC of water annually High temporal and spatial variation in runoff and rainfall High instantaneous flood due to high intensity rainfall up to 350 mm/day Average annual rainfall 1530 mm of which more than 82% occurred during June to September Steep mountain terrain and fragile geology Nepal often suffers from various types of Water induced disasters like floods, landslides, debris flow, GLOF etc Unplanned development activities and lack of land use plan cause further vulnerability The forest cover is 38% but deforestation is continued due to high growth of population Resource constraints and lack of awareness are major obstacles in mitigation of water induced disasters
- 4. Variation of altitude with respect to distance
- 6. Types of Water Induced Disaster in Nepal Floods- Monsoon Flood, Flash Flood Landslide and Debris flow- Fall, Slides, Topples, debris flow, Cause tremendous destruction of productive land, irrigation systems, foot trails, road alignment as well as villages in the hills Shifting, meandering, widening and braiding, scour bank erosion and under cutting and inundation of lower Terai during monsoon, and siltation along the farm land.
- 7. House survived but at risk by landslides
- 8. Rock failure, Siddhartha Highway Damaged Highway
- 9. Debris flow 1993 e.g. Debris flow at Phedigaon, Palung
- 10. Bridge Failure, Seti River, Pokhara

- 16. Floods in Kanchanpur District, 19 September, 2008
- 17. Floods in Kanchanpur District, 19 September, 2008
- 18. Water Induced Disaster Management Policy, Rules and Regulations Natural Disaster Relief Act -1982-amended 1992 Water Resources Strategy – 2002 National Water Plan- 2005 Water Induced Disaster Management Policy-2006 Institutional Arrangements Central Natural Disaster Relief Committee District Natural Disaster Relief Committee River Training Project under DOI in 1970 DPTC established in 1991 Department of Water Induced Disaster Prevention (DWIDP) established in 2000 River Training Division of DOI merged into DWIDP in 2002
- 19. Establishment of DPTC DPTC was established in October 1991 Aims to enhance institutional capability of GON through: Technology development Provision of training and Establishment of data base
- 20. Activities of DPTC.. Office Building at Pulchowk Hydraulic Lab at Godawari Landslide Management at Kath-Trisuli Road Model River Training at Khokana
- 21. Department of Water Induced Disaster Prevention (DWIDP) DWIDP was established in 2000 to institutionalize the objectives of DPTC Responsible for managing and mitigating water induced disasters River Training Division of DOI transferred in 2002 DWIDP has 7 Divisions, 5 Sub-divisions and 2 central Project Offices The DWIDP implements non-structural measures, which mainly, are awareness generating software, trainings, activation of inundation committee, warning/preparedness etc Structural measures are engineering structure like dike, spur, sabo dam, bio-engineering works, river channelization etc.
- 23. Major Activities of DWIDP Settlement and agricultural land protection Infrastructure Protection Provision of emergency relief materials Trainings Public awareness Information Dissemination Hazard map preparation Research and study
- 24. Physical Activities of DWIDP
- 25. Infrastructure Protection Works Highway and roads- Kath-Nuwakot, Charali-Ilam, Kath-Naubise, Mugling-Narayanghat, Sindhuli Bardibas Hydropower- Marsyangdi HP, Irrigation Canals- SMIP Religious and cultural importance places- Manakamana temple, Devighat temple, Changunarayan temple,
- 26. Major Works in MUNA Project
- 27. Major Works in SIBA Project
- 28. Provision of Emergency Relief Materials Bamboo Spurs (Retards) Bamboo Spurs (Retards)
- 29. Training and Seminars Roving Seminars- since 1993 ---50 nos in various districts General course training- 257 nos for junior technicians Advanced course training- 189 nos for senior technicians Intensive course-51 nos for senior levels
- 30. Information Dissemination Data base management and publication Roving seminars IDRR day exhibitions DWIDP bulletin, Disaster Review School materials Higher study course materials
- 31. Issues in Water Induced Disaster Management Settlement in river banks and inside river boundary line pose high vulnerability Cultivation in steep slopes Global warming-glaciers retreat rapidly Lack of flood forecasting system Planning and preparedness for flood disaster yet to strengthen Community awareness is not adequate
- 32. DWIDP would like to network and cooperation from all concerned. Thank You
