Heavy flooding in Ayutthaya affects 6 districts with 5,030 affected households across 240 sub-districts after the Chao Phraya dam increased discharge to 1,750+ cubic meters per second. Authorities are installing water barriers (138 panels, 165 meters long, 1.9 meters high) to protect historic sites like Wat Chaiwatthanaram, with contingency plans including evacuation centers and sandbagging in place. Water levels are rising rapidly and could breach outer banks if levels increase another 70–90 centimeters.
