“Unrealistic and very risky.” Academic warns about cave rescue.

By Pratch Rujianrom
Associate Professor Ariya Aruninta from Chulalongkorn University in Bangkok is warning that the give consideration to evacuating the trapped 13 by drying the cave was unrealistic and really risky.
Draining water out of the Tham Luang cave is an inconceivable mission, she claims, even as the rescue operation makes headway and pumping water from the flooded cave has been thought of the most important challenge to rescue the trapped footballers.
Aria says it’s impractical to regulate the influx of water into the cave system or effectively pump the water out, especially during the wet season. Ariya identified that it was not simply the floodwater contained in the Tham Luang cave system that the rescue team is coping with, however the whole subterranean aquifer system of the entire mountain range.
“The mission’s water-draining capacity cannot match the large volume of water flowing from the mountain through the rainy season,” she said.
“The rescue group has already faced a difficult scenario. The rainy season has just began and the wet weather will unleash its full energy through the four-month period from now.”
She explained that the Tham Luang cave is a component of a limestone mountain ecosystem and when it is raining on the mountain, the water shall be absorbed into the subterranean aquifer system by way of infiltration and later spring out as streams and rivers. She emphasised that the cave can be part of an enormous underground water system. She stated the plan to evacuate the footballers out of the cave by teaching them to dive by way of the submerged cave was a really harmful thought, as a result of the water degree within the cave can rise very rapidly without warning from heavy downpours on the mountain above.
Ariya advised that as an alternative of combating a hopeless battle in opposition to nature, the rescue team should give attention to finding safer methods to get the group out.
Meanwhile, Chiang Rai Governor Narongsak Osotthanakorn said the water drainage operation was probably the most essential process before the rescue group at this second, because the lower the floodwater in the cave the higher the prospect to get the stranded footballers out of the cave safely.
“We are actually specializing in persevering with the well-organised water drainage operation, and a minimal of preserve the current water drainage capacity in order to put together for extra rain,” Narongsak mentioned.
“So far the operation to scale back floodwater inside the cave has been satisfying, because the water degree is slowly however continuously receding at round one centimetre per hour.”
Maj-General Chalongchai Chaiyakham, the deputy commander of the 3rd Army, additionally disclosed that the rescue staff had efficiently drained as much as 128 million litres of water out of the cave system. Chalongchai mentioned the trouble to decrease the water stage within the cave by pumping out groundwater within the area had already removed as much as 350,000 litres per hour from the subterranean aquifer system.
Additionally, Deadline to the South and the North of Doi Nang Non Mountain, Haui Makaeng and Huai Nam Dan, were additionally diverted by way of the cooperation of the local people and related agencies, as per the suggestion of Thailand’s outstanding geologist Chaiporn Siripornpibul to find a way to curb the water influx to the cave system by way of many stream sinks alongside these streams.
Chaiporn, who went to Chiang Rai to look at the streams, said based on his estimates up to 70 per cent of the water in these streams flow into the cave system through many cracks and sinkholes along the pure course of the streams, so he proposed the development of weirs over these streams to cease the water flowing into these stream sinks.
“The water diversion at Huai Nam Dan may be very profitable, as we are in a position to divert as a lot as 50 per cent of the water inflow or 13,000 cubic metres of water through the stream sinks,” he mentioned..
