Overflowing dams pose risk to Hua Hin events
Heavy rains pressuring major dams in Phetchaburi province have sparked fears among tourism operators that the spillover could inundate local attractions and threaten Hua Hin in neighbouring Prachuap Khiri Khan.

Last month's downpours recharged two large dams in the province to near capacity, necessitating the spillover.

Tourism operators anticipate that if business areas in the province are inundated as a result of the spillover, events and meetings that are set to take place in resort towns such as Cha-am in Phetchaburi and nearby Hua Hin in Prachuap Khiri Khan will be affected.

According to Wassana Srikanchana, president of Hua Hin Cha Am Tourism Association, said one meeting with 200 attendants scheduled for tomorrow in Hua Hin is mulling whether to postpone the event or not.

But she has learned that operators mostly plan to carry on with their events, believing that the floods will not reach their venues.

Mrs Wassana said many hotels in Hua Hin and Cha Am are preparing for possible flooding by building temporary barriers and putting sandbags around their properties.

Moreover, they are preparing alternative transport options in case they need to evacuate guests.

Hotels and tourism operators in these areas are conducting business as usual, but vendors located on the bank of the Phetchaburi River and in low-lying areas have already relocated to higher ground.

Mrs Wassana said many events are planned in Hua Hin and Cha-am over the upcoming long weekend for Mother's Day celebrations. If the flood risk is resolved, all events should continue as planned.

She also urged tourists who plan to visit the areas to check travel information.

As the area is in the low season for tourism, the average occupancy rate of some small hotels in Hua Hin and Cha-am may drop to 10-20% this week. The rate is similar to the same time last year, she said.

Four- and five-star hotels are operating at 40-50% occupancy because they have secured business through discounts and promotions a few months ahead of the low season. ... hin-events

Scarce rain a headache in NE, amid continuing flood fears ... recent_box

NAKHON RATCHASIMA: The rush to discharge water from brimming reservoirs at many major dams, with more rain forecast, is in sharp contrast to the major concern at Upper Moon dam in Khon Buri district - where there has been almost no rain for about six months.

Farmers on tens of thousands of rai downstream depend on the dam having enough water to irrigate their crops throughout the rest of the growing season.
Chakkri Yingcharoen, chief of the of Upper Moon irrigation area, said on Wednesday the water level behind the dam had fallen to about 50% of capacity.
While this was not yet alarming, after six weeks with almost no rain falling on the watershed area to top up the reservoir, steps would have to be taken to cope with the situation.

"I was informed on Aug 7 the a royal rainmaking operation has started," Mr Chakkri said.
If successful, artificial rain, generated by a fleet of small planes seeding clouds above areas hit by drought, would raise the level of the reservoir, allowing the dam to support the network of irrigation canals that feed 47,000 rai of cropland.
The dam, built to hold 141 million cubic metres of water, sits on the Upper Moon River in Khon Buri district. The river runs 641 kilometres from southern Nakhon Ratchasima through northern Buri Ram to Surin and Si Saket and then flows into the Mekong River in Ubon Ratchathani, one of northeastern provinces currently suffering from flash floods.

With the Mekong running very high, Ubon Ratchatani and other provinces along the river are on full alert in case it breaks its banks.
The Meteorological Department forecast is for more rain in most areas of the country - except, it seems, along the Upper Moon River.

The rain is being brought by a monsoon trough in the upper North and Northeast, influenced by a low pressure system in southern China and the strong southwest monsoon in the Andaman Sea, the weather office said on Wednesday.

Water is already being discharged from brimming major dams, including the Nam Oun in Sakon Nakhon and Kaeng Krachan in Phetchaburi province, where residents downstream were slowly being flooded out on Wednesday.

But on the Upper Moon River, concern continues to focus on the lack of water flowing into the dam reservoir. Farmers there are praying for rain.
The Upper Moon dam has been supplying irrigation water to farmers since early July. "We need to continue the job until the end of crop season in late October," Mr Chakkri said.

107 reservoirs brace for more monsoon rain
Published: 11/08/2018 at 03:09 AM
Newspaper section: News ... r-scrutiny

As many as 107 reservoirs are approaching maximum holding capacity as technicians race against time to drain them before further monsoons hit the country later this month.

Somkiat Prajamwong, secretary-general of the Office of National Water Resources (ONWR), said on Friday most of the reservoirs are located in the northeastern part of the country.

Among them are four dams -- Kaeng Krachan in Phetchaburi province, Vajiralongkorn in Kanchanaburi province, Pranburi in Prachaup Khirikhan and Nam Un in Sakhon Nakhon -- that the ONWR has put on a "special monitoring" list.

Mr Somkiat said the government has already taken steps to reduce the impact of any overflow into downstream areas.

"Affected villages will be taken care of. We have sent warnings and deployed assistance in advance," he said.

The Royal Irrigation Department (RID) also expressed confidence that the situation was under control.

"We have survived the first crisis. The impact on low-lying land downstream has been contained and cushioned. The new challenge is to drain part of Kaeng Krachan dam to make space for more water from the upcoming rain," said RID chief Tongplew Kongchan.

The monsoon trough will arrive sometime between Aug 20 and early September, according to official forecasts from the Thai Meteorological Department (TMD).

The areas that will be affected are the upper North and upper Northeast, while a strong southwest monsoon will cover the Gulf of Thailand and the West, causing heavy rain.

At least one storm will hit the country in September and is likely to affect Mukdahan, Nakhon Panom or Ubon Ratchathani first, said TMD chief, Wanchai Sakudomchai.

Despite the seemingly ominous weather forecast, Mr Wanchai urged the public not to panic as the intensity of the weather system is likely to weaken as it passes over the Philippines and China.

In the meantime, the country will experience thunderstorms and heavy rain until Tuesday before clear skies return for 10 days ahead of the expected monsoon, according to the Department of Disaster Prevention and Mitigation (DDPM).

Heavy rain this weekend could result in flash floods, forest runoff and mudslides, and the Andaman Sea and Gulf of Thailand could see waves reaching up two or three metres, said DDPM director-general Chayapol Thitisak.

He said people in 57 provinces should be vigilant, noting that 17 of them are in the North, 16 in the Northeast, 15 in the Central Plains and nine in the South.

Another nine coastal provinces were also warned about rough seas.

Bad weather has been felt all across the country this month.

In Sakon Nakhon, a couple of days of heavy rain caused 4 million cubic metres of water to flow into the already brimming Nam Un dam in Phang Khon district.

As of yesterday, the dam remained at 2% above its storage capacity.

Officials at the dam are expediting efforts to release water and said the facility's structure remains strong.

In the southern district of Surat Thani's Phanom district, Moo 1 and 3 in tambon Klong Sok were flooded from canal overflow while strong currents in Klong Bang Man damaged a bridge leading to Moo 2, making it impassable.

Storms force dam discharge
Four reservoirs come under close watch

Published: 13/08/2018 at 02:30 AM
Newspaper section: News ... -discharge

The Nam Un dam in Sakon Nakhon is now holding 102% of its safe maximum capacity, necessitating continued discharge of water downstream with the dam is expected to take more inflow later this week.

Officials said about 4 million cubic metres of water flowed into the dam on Saturday following heavy rain, while the dam is discharging about 5 million cu/m of water per day.

It is necessary for the dam to release as much water as possible -- through all channels including the spillway and irrigation canals -- to take more inflow as several storms are expected to come before the end of the rainy season, they said.

Nam Un is among the country's four major dams now under close watch as they are holding water beyond 80% of their capacities. The other three are Srinagarindra and Vajiralongkorn dams in Kanchanaburi, and the Kaeng Krachan dam in Phetchaburi province.

For the Kaeng Krachan dam, flood draining is now under control and and flood impacts in Phetchaburi province had been controlled and curtailed after massive flood draining efforts early this week, as Prime Minister Prayut Chan-o-cha visited the province to inspect the area.

Srinagarindra and Vajiralongkorn dams are continuing to discharge 66 million cu/m daily combined after reaching 87% and 85% of their storage capacity respectively, according to the Royal Irrigation Department (RID).

Vaivij Sangpanitch, director of Vajiralongkorn dam, said the 43 million cu/m water has been drained daily, insisting the reservoir would have space to cope with rains expected to come the end of this month.

Prasert Inthab, director of Srinagarindra dam, said the draining of over 23 million cu/m daily provided capacity for taking more water by the end of this month.

He said dam officials gave prior notice to the village downstream about water draining and provided assistance for villages that might experience rising water.

Meanwhile, the Thai Meteorological Department (TMD) said about 60% of Sakon Nakhon province faces the threat of floods from tomorrow until Friday.

People have been warned of heavy rain, flash floods, overflows from streams and landslides.

Residents in the North and Northeast are also warned to expect flash floods and mudslides in the next few days, triggered by tropical depression Yagi hitting Vietnam Monday.

The depression, with a wind speed of 50 kilometres per hour, will move from the South China Sea to upper Vietnam Monday and Tuesday and will cause heavy rain across the northern and northeastern regions of Thailand, according to the TMD.

The weather bureau also said a southwest monsoon in the Andaman Sea and Gulf of Thailand could cause large waves of between two and four metres in some coastal areas.

Fishermen and boat owners are advised to exercise extreme caution while small boats should stay ashore.

Meanwhile, flash floods from a local mountain range have submerged agricultural areas in Phato and Lang Suan districts after Chumphon was battered by five consecutive days of heavy rain.

Locals have been forced to move their belongings to higher ground and evacuate their animals. The extent of damage to farmland is not yet known.

In Kanchanaburi, six families in Sangkhla Buri district urged state agencies on Sunday to speed up efforts to provide them assistance after their houses were damaged by a landslide caused by heavy rainfall last month.

All of them have been living in temporary accommodation since July 20.

The villagers earlier sought help from Tambon Wang Ka municipality which at the time sent authorities to examine their houses' condition. However, the municipality has yet to take any further action.

In an update on the general situation, Chayaphol Thitisak, chief of the Department of Disaster Prevention, said the flood situation caused by the tropical storm Son-Tinh has receded.

Khao Yai hit by severe runoff
Downtown Nakhon Nayok at flood risk

Tourists at Khao Yai National Park in Nakhon Nayok were warned yesterday to steer clear of Nang Rong and Wang Takhrai waterfalls and stay on high ground because of mountain runoff caused by heavy rain.

The water level at the two waterfalls rose rapidly Monday afternoon, prompting authorities and resort operators to issue stern warnings.

About 30 tourists including a film crew have been stranded at a riverside resort but all the crew are safe.

Worapan Suwannut, deputy governor of Nakhon Nayok, said operators of riverside resorts had been asked to monitor official announcements closely over the next two days and suspend services for safety reasons if necessary.

Thai PBS broadcast an alert Monday night that floods would soon hit the downtown area.

Dramatic footage captured by the network show the fury of Monday's flash floods.

He said authorities are on standby around the clock and were mobilising resources to help the stranded tourists and escort them out of the resort.

Akkharadet Yodjumpa, a singer better known as Kong Huayrai, live-streamed that he was stuck at the resort in Wang Takhrai following heavy rain and runoff.

The singer, who was with a film crew, said he and the others were safe and at about 6pm he posted that the water was receding.

Sirinan Maneechote, chief of Nakhon Nayok's disaster prevention and mitigation office, said provincial authorities had issued a warning to local residents about a possible surge in the water level.

Wichai Pornleesaengsuwan, a national park official, said the runoff, the worst in 10 years, was triggered by heavy rain on the mountain. On Sept 25, 1994, a flash flood killed 21 people at Wang Takhrai.

In Phuket, in the South, tourists were warned Monday not to swim at several beaches due to rough seas and strong winds.

Red flags were put up at popular beaches where trees have been toppled by gusting winds brought on by the monsoon surge. Many beach roads were also covered with thick sand.

In Chumphon, Monday rainstorms caused damage in Lang Suan district in the early afternoon.

Motorists were left stranded when a section of the southbound Asian Road at the 70th-kilometre marker was blocked by fallen trees.

On the Bangkok-bound route, a tree fell on a car, shattering its windscreen and bonnet. No one was injured.

Motorists on Phetkasem Road have been warned to be wary of loose soil on the road between Ranong and Chumphon.

The Office of National Water Resources has warned residents about possible flooding along the Phetchaburi River in Phetchaburi, the Kra Buri River in Ranong, and Takua Pa River in Phangnga.

In Phetchaburi, high-risk areas include the low-lying and riverside communities in districts of Kaeng Krachan, Tha Yang, Ban Lat, Muang and Ban Laem.

Meanwhile, residents in the North and Northeast have been urged to brace themselves for rain tomorrow and Thursday as a tropical storm moves across the upper part of Vietnam.

People near the Andaman Sea and the Gulf can also expect rough seas and strong winds, with larger vessels told to proceed with caution and small boats advised to stay ashore.

In Kanchanaburi, officials at Srinakarind dam and Vajiralongkorn dam Monday gave assurances that the reservoirs can receive more water and their structures are not compromised.
