The disaster that lives a poor and small nation like Laos shocked the world yesterday. Six humble villages were completely sunk by 5 billion cubic meters of water released after the collapse of the Xe-Pian Xe-Namnoy hydroelectric dam in Attapeu province, in the south of the country
. a communist country, with a tight government to inform the international media – and more in case of disaster – some information was known. At the end of this edition, 6,600 people were left homeless, 20 were confirmed dead and at least 100 disappeared.
The country is trying to rescue those who have been separated from their families and to take care of thousands of They have been left homeless. The Red Cross has announced the dispatch of "emergency kits to help 1,000 people displaced by the floods," although more supplies are needed.
Be that as it may, the eyes of the world were also focused on what was happening in the world. dam and the causes of this disaster. While the communist regime of Laos did not report its badumptions, other details were known to the owner of the consortium of the work
composed mainly of the Thai company Ratchaburi Electricity Holding Holding and the South Korean company SK Construction. Co., informed the British BBC of what happened.
It should be remembered that the region was hit for a week by the heavy rains of typhoon Son Tinh, which left 32 dead and 15,000 homes destroyed.
Heavy rains quickly filled the reservoir of the hydroelectric dam, in which there are three dams, a main and two auxiliaries. One of these, called "Dam D", suffered a fracture "due to the continuous flow of water that went into the reservoir and collapsed."
Attention, more details should be known, Osvaldo Ordoñez, Researcher in Geoscience and Expert in Hydroelectric Projects of the U.National, felt that "engineers must take into account the worst possible scenarios in the calculations, it is therefore foreseeable that this has not been done in the case of the Laos dam, with these 5 billion cubic meters of water. "
By badyzing what is Has pbaded, does it have any similarities to what the Hidroituango project in Antioquia experienced between May and June? The experts consulted differ
According to Ordoñez, there is a space to compare the two situations: "if the dam is not high at the 410 level in Hidroituango, if the winter followed and it was n 39; there was no alternative to the central, the destruction would have been brutal.That's what happened. "
For the engineer Santiago Ortega expert in hydraulics and teaching at the EIA University, "there is no similarity with Hidroituango because they are two completely different failures.A dam fall and a break in a diversion tunnel."
