The Royal Irrigation Department (RID) is preparing for an anticipated increase in rainfall as the La Niña weather pattern is expected to begin in the coming months. During an online session at the RID’s Smart Water Operation Center, RID Director-General Chuchart Rakjit outlined proactive measures to manage the expected surge in rain from July to October, which coincides with Thailand’s rainy season.
Meteorological experts predict that La Niña will result in a 20% increase in overall rainfall, with the Central Plains region experiencing the most significant rise at 39%. The Northeast and South are also expected to see increases of 22% and 16%, respectively. The frequency of rain is predicted to escalate, particularly from August to October, influenced by dual monsoon winds.
In response to these forecasts, the RID is implementing measures to mitigate potential flooding risks. The memory of the 2011 megaflood, which caused severe flooding in 65 provinces, is still fresh, but Chuchart assured that the likelihood of a similar disaster is low this year due to technological advancements and improved water management systems.
Significant upgrades have been made to the infrastructure along the Chao Phraya River. All pumping stations have been overhauled, enabling them to efficiently direct excess water to the Gulf of Thailand. The RID has also optimized the use of water-retention areas, designed to hold 1.5 billion cubic meters of water, surpassing the capacity of Pasak Jolasid Dam.
Officials, including Chuchart Rakjit, emphasized the importance of these measures in protecting communities and agriculture from potential flooding. Enhanced technology and strategic planning are central to the RID’s efforts to manage the increased rainfall and ensure the safety and well-being of affected regions.
