How engineers in a WhatsApp group are guiding Nepal’s flood rescue efforts

The messaging group was set up by engineers before the wall of water, mud and rock crashed down the Trishuli valley in Nepal on August 26. It has since become a valuable tool alongside helicopters and heavy machinery in the race to find survivors. The authorities hope some of the about 900 people reported missing from six hydropower plants – at least three of which were under construction – may have escaped the deluge because they worked in or fled into the tunnels. Even finding entrances to some of the tunnels, which were designed to channel water or used to access hydropower facilities, is tough now after the flood deposited 2.2 million tonnes of mud and debris down the valley. ‘SEND ME LAYOUT DRAWINGS’ “Can you send me Chilime layout drawings,” a government official wrote on the engineers’ WhatsApp group on Saturday
