Abstract

The flooding of Krueng Langsa river occurs every year. The floodwaters submerged people’s homes around the river. Every year SAR teams and communities have difficulty evacuating. This is due to the lack of flood zoning maps and evacuation routes. To reduce the risk of flooding overflowing in the Krueng Langsa river, evacuation route maps and zoning maps of flood hazard areas are needed., it is necessary to map evacuation routes in each hamlet as well as a zoning map of flood hazard areas. The purpose of this research is the availability of zoning maps and evacuation routes as one of the mitigations to reduce the risk of Krueng Langsa river overflow disaster. The data used is measurement data in the field and interviews. The data is analyzed using QGIS and CAD. The zoning mapping of insecurity levels is divided into 4 levels based on the weighting score of parameters that affect flooding. This map illustrates the direction of movement of each person to the gathering point and evacuation place. The evacuation route is chosen based on the distance to the collection point, the direction of the water flow, the height of the floodwater level, and the high ground level.
