Spatial Flood Potential Mapping (SFPM) with Flood Probability and Exposure Indicators of Flood Vulnerability: Case Study Former Jalpaiguri District, West Bengal, India

Moitrayee Das, Anis Chattopadhyay and Ranjan Basu

Flood is an annual event in the district of Jalpaiguri. Almost all the administrative blocks of the district are more or less flood prone. Like the administrative blocks almost all the rivers in the district are also flood prone. Due to this every river has certain flood level as well as danger level to observed the flood situation in the area. Following the past observation of flood level crossed by the river the probability of current event can be obtained. In this paper the authors are tried to show the spatial distribution of flood potential in the district with the help of probability analysis of flood event of individual rivers and exposure indicator score of the adjacent area. Here probability explains number of chance of flood in Individual River and exposure indications explain how much the area is exposed to flooding. The mapping is based on spatial flood potential index (SFPI).
