Ayutthaya province has put up dykes along the banks of the fast-swelling Chao Phraya River, which is threatening to overflow and flood homes and historical sites. The province's industrial estates reported on Wednesday that no flooding had affected them yet. Meanwhile, industrial estates in Ayutthaya have raised flood barriers around their properties to over 1.8m. Veeris Ammarapala, governor of the Industrial Estate Authority of Thailand, said the risk of flooding in the industrial estates is low. Effective flood prevention measures have been in place at industrial estates since the disastrous floods of 2011.
