Anticipatory action simulation on flood hazard: case study of Matara District, Sri Lanka

This case study explores a large-scale community flood simulation exercise that was carried out on 15–16 September 2025 in the Wellathota and Katuwangoda GN Divisions of the Matara District, Sri Lanka—areas highly vulnerable to recurrent flooding. This exercise was designed as a practical, hands-on simulation to strengthen Locally-Led Anticipatory Action (LLAA) and enhance the disaster readiness of communities. By engaging communities directly in a participatory process, the simulation aimed to test the effectiveness of early warning systems, validate evacuation routes and preparedness measures, and strengthen the operational capacity of Village Disaster Management Committees (VDMCs).

Communities practised vital preparedness and readiness actions such as canal cleaning, early harvesting, securing essential items, preparing go-bags, checking rescue boats, installing indicator poles, and safeguarding livestock. During the Active Phase, actions included mock cash assistance, first-aid demonstrations, focused support for vulnerable groups, and establishing safe spaces for children. Evacuation drills were conducted efficiently, with families relocating to shelters and engaging in camp management activities coordinated by disaster management officials and Family Health Officers. After the “all clear” signal, families returned home, cleaned the shelters, and participated in a reflection session to identify strengths, gaps, and lessons for improving future flood preparedness.
