Nepal Flash Floods 2026

On 26 August 2026, catastrophic flash floods tore through the Tibetan and Nepal border, entering the BhoteKoshi river system at approximately 09:00 NPT, causing widespread destruction in Timure, Rasuwagadhi and Syafrubesi before moving downstream along the Trishuli river corridor. Authorities have now confirmed that a glacier collapse triggered a landslide and flash floods that swept away entire villages downstream. The initial impact of the glacier breaking off and hitting the valley floor was so powerful that it registered an earthquake of 5.2 Magnitude on the Richter scale. As a wall of ice, mud and rock barreled down the narrow river valley, the powerful flood waters and debris swept through towns and villages along the Bhotekoshi and Trishuli river corridors. The incident caused significant loss of life, displacement and damage, particularly in Rasuwa district and the Bhote Koshi –Trishuli river corridor including Nuwakot and Dhading districts. Houses and settlements have been washed away or severely damaged, while roads, bridges, hydropower facilities, vehicles and other critical infrastructure have sustained major damage.Habitat for Humanity Nepal is on the ground in Rasuwa and responding to this crisis in close collaboration and coordination with the authorities, and other humanitarian and development partners.

As of 1 September, the death toll has reached 939, more than 3,925 people remain missing, and over 10,000 households have been displaced. Behind every number is a household that lost its home in minutes and is now deciding what to salvage, and where to spend the night. Rebuilding safe, permanent housing for displaced families is what Habitat for Humanity Nepal does. Your support helps us reach affected communities first with emergency shelter, then with the materials, skilled labor and construction know-how needed to rebuild homes that can withstand what comes next.

THE PLAN

How our response unfolds

Habitat's response follows a phased path immediate shelter first, then durable recovery so support arrives when it's most useful.

Phase I - Emergency response

First 0-3 months (Sept - Nov)

Emergency Shelter Kits (ESKs) distributed so families can make immediate repairs and put up temporary shelter while the situation stabilises.

  • Distribute Emergency Shelter Kits (ESKs) for 1000* families
  • Support local governments with needs assessment

Phase II - Transitional recovery

Early Recovery (Nov - August) 10 months*

Durable transitional shelters with basic sanitation, alongside conditional cash transfers that let families meet their own most urgent recovery needs.

  • Transitional community shelters in 3 communities
  • Transitional shelter construction using local material and local techniques for 300 families
  • Conditional Case Support – shelter repair/ rental support for 700 families
  • Support local governments with detailed damage assessment
  • Monitoring and evaluation

THE CHALLENGE

Why building here is hard

Steep, remote terrain and damaged road access shape everything about how and how quickly shelter can reach these communities.

IMPACT MAP

Path of the catastrophic floods

The floods entered Nepal via the Lhende Khola, a Bhotekoshi tributary on the Tibet border, then surged south through Timure and Syabrubesi into the Trishuli river system reaching Nuwakot, Dhading, and Chitwan as it moved further downstream, leaving a trail of destruction.
