GIS‐based disaster management: A case study for Allahabad Sadar sub‐district (India)

This paper aims to demonstrate a Geographic Information System (GIS)-based study on development of District Disaster Management System for floods for Allahabad Sadar Sub-District (India). An approach has been designed to explore the scope for the combination of Disaster Management and GIS. The flood-prone areas have been identified and their positions are marked using ArcView 9.1. GIS has been exploited to obtain the spatial information for the effective disaster management for flood-affected areas. ArcView 9.1 has been used as a tool for storing all types of relevant data for analysis and decision making. The various thematic maps include road network map, drinking water sources map, land use map, population density map, ward boundaries and location of slums. The paper proposes evelopment of a GIS-based early response system, and an emergency preparedness plan for the Allahabad Sadar sub-district and also analysis of the impact of flood disasters in the region and its relationship to infrastructure development with a view to identifying how local governing bodies could be helped in addressing these issues. The proposed GIS-based flood mitigation and management program would improve the current practices of disaster management process. If implemented properly, it would result in proper and quick decisions for the rescue and safety of the general public, which in turn would help in minimizing loss of life and property.
