PETCHABURI, 7 August 2018 (NNT) – Overflowing water from Thailand’s Kaeng Krachan province is expected to begin impacting Petchaburi province communities tonight with riverside areas likely to see 50 centimeters of water that could remain for up to two weeks.
Deputy Prime Minister, Gen Chatchai Sarikalya, Secretary-General of the Office of National Water Resources (ONWR), Somkiat Prajamwong and Royal Irrigation Department (RID) Director-General, Thongplew Kongchan, all traveled to Petchaburi province to inspect the situation at Kaeng Krachan Dam, which is releasing water at a rate of 150 million cubic meters a second. Authorities have installed 30 water pumps in at-risk areas, 44 water jets to speed up drainage to the sea of the Petchaburi River and stationed heavy machinery to open up any blockages that may occur.
The water management plan is to divert portions of the overflow into the irrigation system. The Petchaburi River has already been drained in anticipation of more water and dykes have been shored up. While waters will pass through Nong Ya Plong, Ta Yang and Baan Lad, no major impacts are expected. Flooding of up to 50 centimeters is anticipated in central Petchaburi, where the river is narrowest, with inundation to last for about two weeks.
Thongplew officials say that efforts to keep waters underneath the spillway at Kaeng Krachan Dam have been successful and allowed for Petchaburi River and irrigation canals to be sufficiently drained. Once waters exceed the spillways this August 10-11, releases will increase to 300 million cubic meters a second for one to two months. Measures to defend against flooding will be in place for an initial seven to 10 days.
The temporary crisis center has, nonetheless, issued a warning that overflows from Kaeng Krachan Dam will begin affecting areas from midnight tonight (August 7).
