Sutat Weesakul of the Asian Institute of Technology’s Water Engineering and Management Programme in The Nation:
Sutat called on other government agencies to assist the RID more with its important mission and urged people to stop protesting against authorities’ efforts to tackle the floods.
He said the flood-water level in areas near Khao Mao and Bang Wa watergates would rise only a little when the gates were completely closed.
The water volume that the authorities have now had to try to push into the sea is the second-biggest on record, he said. The largest volume was in 1942, while the third-biggest was in 1995.
Some 450 million cubic metres of water are currently being pushed into the Gulf of Thailand per day. At such a rate, the accumulated run-off volume will still rise by 150 million cubic metres daily, flooding more areas, he calculated.
It will take about 40 days for the 12 billion cubic meters of water, enough to cover Connecticut a meter deep, to drain into the Gulf of Thailand, Irrigation Department spokesman Boonsanong Suchatpong said yesterday. The floods have swamped industrial estates north of the capital with as much as three meters of water.
Rainfall about 25 percent more than the 30-year average filled upstream dams to their capacity, prompting authorities to release large amounts of water this month down a flood plain the size of Florida.
BP: The figures mentioned between Sutat and the Irrigation Dept spokesman don’t match up, but you are talking about 30-40 days for the water to drain into the Gulf of Thailand. That is a lot of water.
The threat of serious flooding in Bangkok is growing because of the volume of water running down from the centre of Thailand, and one inner city area was under threat on Thursday after floodwater breached a waterworks canal, officials said.
Pracha Promnok, justice minister and head of the government’s flood crisis centre, told Channel 3 television that city officials had been pumping water out overnight in the Samsen and Makkasan areas, which are just north of the royal palace and other sites visited by tourists.
“I’m worried about Bangkok residents because if we can’t control the situation or things go wrong with the water pumping machine or we can’t pump water in time, then there’s a chance that our Bangkok will be swamped,” Pracha said.
The water level early in the morning was still manageable, he said.
The cost to the economy could go far higher if Bangkok is swamped. The capital accounts for 41 percent of gross domestic product.
BP: Those industrial estates flooded pale into comparison on the economic cost if Bangkok floods and the level of the flooding is say more than one meter, but what compensation will be provided to those that are flooded?
btw, that third line of the second paragraph of the Reuters article made BP think of some more criticism the government would face if Bangkok flooded and the water levels were high….
