Flood Hazard Mapping and Road Network Vulnerability Analysis of Kamrup and Kamrup Metropolitan Districts: Case Study of Assam Flood 2019

Bateswar Das

Abstract: Kamrup district is highly flood vulnerable due to riverine flood of Brahmaputra. The district is administrative center of Assam state and geopolitically significant for India to connect with North-East states. Majorly NH 17 and NH 27 passes through the district and connects the NE states with Assam and rest of India.Due to flood vulnerability the largest resource supply chain network of the country face damage and disruption. In this study flood vulnerability map was prepared using information and past flood data of Kamrup and Kamrup metropolitan districts following the Assam flood 2019. AHP-GIS based flood susceptibility zonation (FSZ) model was used to show the vulnerability and further NH17 and NH27 was super imposed on FSZ map to show the vulnerability in supply chain. The FSZ map was validated using AUC method which estimates the FSZ map in fair category, prediction and success rates are 0.620 and 0.718 respectively. The study creates scope of road network vulnerability assessment using AHP-GIS method in the hazard prone areas of the country in order to develop sustainable planning.
