The dyke at the Bang Chom Sri water sluice gate in Sing Buri’s In Buri district collapsed on Sept 13, unable to withstand the strong Chao Phraya River currents, causing flooding in Sing Buri and nearby Lopburi provinces.
Accompanied by Deputy Prime Minister and Minister of Interior Yongyuth Wichaidit, the premier left Bangkok by helicopter.
Yingluck was briefed that the water levels in the Ping, Wang, Yom, Nan Rivers which form the Chao Phraya River are still high. The water level of the Chao Phraya River measured at Bangsai district in Ayutthaya was 3,236 cubic metres per second but will not cause flooding in the capital.
However, if it surpasses 3,500 cubic metres per second, Bangkok will be affected.
Director General of Royal Irrigation Department Chalit Damrongsak said the department has expedited diverting flood water into the sea and several branches of rivers. Regarding the damaged dyke, he said rocks in a metal net were dumped at the Bang Chom Sri sluice gate around the clock to slow down torrential current and it will take time to repair it due to strong current.
He also ordered officials to inspect flood prevention walls along the Chao Phraya River as they could be damaged by prolonged floods.
Yingluck said she ordered the royal irrigation department to install more machines to drain flood water and dredge canals to facilitate releasing water into the sea.
She said it will take about 15 days to fix the dyke at the Bang Chom Sri sluice gate due to strong current. It is also difficult for large trucks to transport rocks to the sluice gate as flood victims were migrating to the roadside.
