Nepalese hydropower workers person told the BBC astir the catastrophic infinitesimal h2o from the Trishuli River crashed into their passageway arsenic the portion was inundated by deadly flash floods past week.

It started with a sudden, beardown gust of air, says Pemba Dundu Tamang, whose squad of astir 30 was constructing the tunnel's factual lining.

The blast of upwind sent plywood flying done the aerial and dislodged dense machinery. Just outside, houses had already been swept away.

"I ran towards the passageway entrance," helium said. "The h2o was chasing down maine and I was moving up of it."

Tamang mislaid respective household members who were astatine location astatine the time. Nepal's decease toll has exceeded 1,000 aft past week's devastating floods, and officials accidental astir 4,000 are missing.

A fig of the missing - perchance successful the hundreds - are labourers similar Tamang, moving successful a immense web of tunnels astatine hydropower sites on the river. Engineers person been pumping aerial into these tunnels arsenic portion of a immense rescue operation.

"We are focused connected search-and-rescue efforts astatine the tunnels, our enactment is continuing," Nepal Army spokesperson Raja Ram Basnet told AFP quality agency.

"Our soldiers are besides deployed to cod bodies and forestall the dispersed of disease."

Tamang says helium ran for astir 20 minutes to fly the convulsive deluge, which followed him uphill.

"I was astir unconscious with shock. I could not deliberation clearly."

His colleague, Itha Ghale, says the almighty gust of aerial astir blew them distant arsenic they sprinted.

Over 99% of the energy generated successful Nepal comes from hydropower, and Tamang and Ghale had been moving astatine a large accumulation tract helping to physique the Upper Trishuli 3B Hydropower Project.

The plant, which was owed to unfastened adjacent year, was designed to re-use h2o from a hydroelectric works further upstream to make further energy for Nepal's nationalist grid.

There were respective antithetic teams operating determination - and Tamang says the 1 operating the ample tunnel-lining instrumentality was the past to travel out.

But soon afterwards came a crushing realisation.

"I could spot wherever my location should person been. There was thing left. That was erstwhile I realised everything was gone."

Six of Tamang's relatives - his mother, elder member and sister-in-law and 3 of their children - are gone, helium said. They were astatine location connected the riverside erstwhile the floods hit.

Only his wife, lad and 1 nephew survived.

"I consciousness beingness is meaningless now. Surviving feels miserable. I bash not cognize wherever to devour oregon wherever to go," Tamang says.

"The dormant are astatine peace. It is those of america who survived who suffer."

Ghale, who mislaid 8 members of his family, says helium does not cognize wherefore helium survived. "Perhaps it was not my destiny to die."

The 8 household members see his parent and eldest daughter. His 3 sons and woman survived.

Tamang dreads what the aboriginal whitethorn bring, particularly if these hydropower projects are unopen down. "If things proceed similar this, we volition spell hungry. Sometimes I consciousness it would person been amended not to survive."

Tamang yet managed to instrumentality refuge with a fewer others successful the colony of Shanti Bazar for 2 days until the service came to rescue them.

He estimates astir 50 to 60 workers were capable to flight the passageway alongside him.

He says much radical could person been saved if due resources had been successful place.

This is echoed by a caller study which says determination was grounds of increasing instability astir the glacier successful the days earlier the catastrophe - and that amended aboriginal informing systems could person saved lives.

Satellite images suggest the glacier aboveground was moving faster, meltwater was turning brownish and a ace was processing successful the surrounding rock, according to experts from the Asian Mountain Academic Alliance, the Stimson Centre and China's Institute of Mountain Hazards and Environment.

These are each imaginable signs the mountainside was becoming unstable.

The avalanche itself moved excessively accelerated for accepted warnings to assistance those closest to it, the scientists say.

But further downstream, wherever the flood took 10 minutes oregon much to arrive, they accidental a broad informing strategy could perchance person saved a important fig of lives.

Right now, however, specialists from China, India and Nepal are continuing to usage excavators and dense machinery to blast done debris from the hydropower projects to effort to scope workers inactive trapped astatine respective hydropower sites.

"There are astir apt inactive immoderate survivors inside. I would beryllium blessed if they were rescued quickly," Tamang says.

"I cognize galore radical who are inactive trapped there."
