Grounded prescription
Stand Up a Live Riverine Flood Watch for the Brahmaputra, Padma, and Meghna Before the Next Monsoon PeakBangladesh's three main rivers breach danger stages each monsoon, yet MoDMR has no live flood indicator feeding decisions; this brief sequences a public danger-stage tracker, pre-agreed evacuation triggers, and anticipatory cash to cut losses.
