Mr Surasi said that from the assessment of the water situation at the end of September – October 65, it was found that there was a trend of increasing rainfall. Including the trend of the monsoon trough lying across the central and eastern regions. As a result, the amount of water in the central, eastern and lower north-eastern regions tends to increase and the Meteorological Department and the Water Resources Information Institute. (Public Organization) said there is a tendency for 1-2 storms to enter Thailand. It is expected to come in early October 65, which will require continuous monitoring and assessment of the situation.
Therefore, today’s meeting has considered together deciding on water management criteria. to reduce the impact that will happen to the people as much as possible From monitoring the current situation, it was found that the volume of water above the Chao Phraya Dam is about 2,200 cubic meters (cu.m.) per second, while at the end of the Chao Phraya Dam Phraya. Drainage at a rate of approximately 1,980 cubic meters per second.
However, if the volume of water above the Chao Phraya Dam is at 2,500 cubic meters per second, water will be controlled down to the Chao Phraya Dam. and drains to the east and west of the Chao Phraya Dam by considering the amount of water from the Pa Sak River Basin that will flow to join Initially, the amount of water at Bang Sai District Station, Phra Nakhon Si Ayutthaya Province is 3,000 cubic meters per second, which is reduced from the original rate of 3,500 cubic meters per second in order to manage the risk of heavy rain in the Bangkok and its surroundings giving the Chao Phraya River good drainage potential. can support the drainage from the urban community effectively
“In addition, water will be managed by using the 10 reservoirs of the lower Chao Phraya River Basin. There will be a process of participation with the people of the area. With the Royal Irrigation Department providing information to the front water management center in the central flood risk area, Chainat province, when considering diverting water to the fields. and the province will publish the criteria for receiving water to the fields for the people to know in advance Get water to the fields in an amount that will not cause any impact or damage to the people.
In addition, INC has assigned the Ministry of Agriculture and Cooperatives. Consider supporting the release of fish to be used as food and generate additional income for the people during the water intake period. And there will be faster drainage of water from the fields once the situation is resolved. There will still be some water left. According to the policy of General Prawit Wongsuwan, the Deputy Prime Minister As the director of the INC to be used for growing crops in the dry season It must be a plant suitable for the amount of water available, which cost available,” said Dr Surasi.
Mr Surasi further said that for preparation in the event of a large amount of water above the Chao Phraya Dam, the ICC has assigned the Meteorological Department and the Water Resources Information Institute. (Public Organisation) uses forecasts of the trend of maximum rainfall or a cyclone event occurring. To be used as a guide for estimating the amount of water above the Chao Phraya Dam and water management guidelines. As a result, the rainfall is more than 20% of the normal value, therefore, proactive measures have been taken in advance, such as preparing water depletion in various dams, etc. The current situation of large dam water volumes can still handle a lot of water especially large dams in the north So, it can hold water if a storm comes in. as well as being able to store and use water for growing crops during the dry season
However, for some large, medium and small dams, which currently have a significant amount of water, the IRS has warned the Royal Irrigation Department to adjust the criteria to increase drainage and must watch if there is more rain. The situation must be carefully monitored The ICC will assess the risk areas and alert the relevant agencies to manage the water in accordance with the situation.
“At today’s meeting Had discussions with Bangkok on increasing drainage efficiency in Bangkok The two pumping stations, various canals, etc., for water management in the Bangkok area, currently, the Bangkok Metropolitan Administration and the Royal Irrigation Department. Every canal in Bangkok has a connection to water management. Go out to the rivers and prepare equipment to support them if there is a lot of rain Including getting rid of water hyacinths and garbage, Gen.
