GIS Support in Disaster Management and Crisis Response

• Using GIS for Effective Response in Floods, Tsunamis, Earthquakes, and Conflicts

GIS Support for Disaster Response

GIS offers critical support in managing natural and human-made disasters, providing real-time data collection, mapping, and decision-making tools. In various scenarios, GIS enhances the ability of emergency response teams to assess risks, plan evacuations, distribute resources, and expedite recovery efforts.

Disaster Response Methodology:

1. Flood Response:

Methodology:

• Real-time Monitoring: GIS uses satellite imagery and water-level sensors to monitor rising water levels, predict flooding areas, and provide alerts.
• Flood Risk Zoning: GIS helps identify flood-prone zones by analyzing historical data and current topography to create flood risk maps.
• Resource Allocation: Using live data, GIS assists in distributing emergency resources and planning evacuation routes.

Tools:

• Flood Modeling: Models such as HEC-RAS integrated with GIS simulate flood scenarios and predict water flow.
• Remote Sensing: Satellite imagery from sources like Landsat or Sentinel is used to detect flood extent and water bodies.
