Academics at a Rajadamnern forum say Thailand is stuck in a reactive flood-response cycle and needs long-term water management reform. The worst current zone is the Bang Pakong basin (Prachinburi, Chachoengsao, Nakhon Nayok), with about 1,700 million cubic metres of standing water that may take at least 30 days to drain. Flood-risk projections for Bangkok rise to 2030 and beyond. For a small business in these areas, check flood-proofing, stock, and delivery routes now, and expect disruption in the coming weeks.
