What this diagram shows

  • The river sensor triggers the process automatically
  • Shelters are assigned by village and capacity
  • Headcounts at camps are reported back in real time

Prompt used

Flood evacuation sequence: a river sensor reports the danger level to the district emergency operations centre (EOC). The EOC issues an evacuation alert to village officers and citizens by SMS. The shelter system assigns villages to relief camps based on capacity. Transport (buses and boats) is dispatched. Camp managers register arrivals on a mobile app and headcounts flow back to the EOC dashboard.
