A major flash flood struck Nepal’s Rasuwa district on Wednesday morning, sending a powerful surge of water, sediment and boulders through the Bhote Koshi and Trishuli river systems, raising concerns over further potential downstream impacts. “We are deeply saddened by this tragic disaster, which struck so suddenly and unexpectedly,” said Pema Gyamtsho, Director General of ICIMOD. “We stand in solidarity with the people and Government of Nepal during this difficult time. Our thoughts and prayers are with the victims, their families and all those affected, and we are committed to providing support wherever possible.” According to local reports, water levels in the Bhote Koshi basin began rising rapidly around 9:00 AM local time on August 26. The flood breached riverbanks and travelled downstream through the Bhote Koshi River into the Trishuli River, with potential impacts extending into Nuwakot and Dhading districts. Scientists from the International Centre for Integrated Mountain Development (ICIMOD) and partner institutions in Nepal and China are investigating whether the flood may have been triggered by an ice-rock avalanche originating from a high-altitude area. Preliminary assessment based on video footage and information from affected areas suggest that a large volume of ice and rock debris may have entered the Lende Khola, a tributary of the Bhote Koshi River. Researchers say the event could have generated a sudden surge that carried water, sediment and large boulders downstream.#nepalflood - @newshubtv
