For the people in their Kanchanaburi resort, the rainy weather made itself more than clear, with torrential rain beating down across parts of the Kingdom, with strong winds, leading to several dams in the province nearing their bursting point.
In particular, the Vajiralongkorn dam, located in Thong PhaPhum district, reached high levels of water by August 16, 2018, being 87.86% full at that morning, which had an average water inflow rate at 132.05 million m3/day, as reported by dam officials. Additionally, the sub-committee for the dam, which makes the decisions regarding the structure’s water management policy, decided to adjust the discharge rate of excess water, raising it to 43 million m3/day, which started on the 16th of August.
Reportedly, following the adjustments, the dam could receive an additional 1.07 billion m3 more water, with officials adding that the dam’s structure was still reliable, as based on results from the conducted daily checks.
Meanwhile, Si Sawat district’sSrinakarin Dam sat at 87.8% capacity, and was estimated by its Director to be capable of holding of an additional 2.1 billion m3 of water.
According to said Director, water was flowing into the dam at double the rate that the dam was discharging the excess, but that it would be strong enough to handle all the additional pressure from the high volume of rain. Hi-tech equipment, he says, was deployed to ensure that the dam was stable and safe as part of response efforts.
Relentless torrential rain has been raining down in the province, leaving people to stay indoors in their homes, or their Kanchanaburi resort, away from the rain. The districts of Sai Yok Thong PhaPhum and SangkhlaBuri were hit particularly hard, resulting into a huge volume of run-off flowing into the dam downstream; the Vajiralongkorn.
In the SakonNakhon province, PhangKhon district, the Nam Un dam was also brimming with water around the same time, due to the fact that the discharge rate of 2 million m3 was almost matched by the rate of inflow.
In the province, about 91% (161) of the 177 reservoirs were over 80% capacity, which highlighted the need for escalating drainage efforts as well as reducing the damage on areas that are either flooded or prone to being such. Residents are already expected flooding to escalate from last year.
