‘Layer upon layer of miracles’: How Nepal flood survivors were rescued from tunnel

Arnold Dix has been advising Nepal's hydropower authorities on how to dig through the blocked tunnel to Trishuli 3A Hydropower Station, which was one of several stations hit by last week's massive flash flood on the Nepal-Tibet border.

Rescuers heading to 'Goldilocks zone' Dix estimated that they had dug about 60m from the entrance by now, and they would need to dig another 150m more to reach the hydropower station located deep inside the mountain.

Using excavators and pumping machines, Nepalese rescuers dug a series of trenches from the tunnel all the way to the river outside, so they could drain the water.
