Flood Risk Analysis Using Remote Sensing, GIS and Analytical Hierarchy Process in Painganga River Basin of Buldhana, Maharashtra, India

The current study seeks to recognize flood hazard risk zones along the course of the Painganga river basin in Buldhana district, Maharashtra. The primary purpose of the research is to develop a geographical information system and analytical hierarchy process techniques-based model for flood risk zonation mapping. This investigation applies several multi sourced ecological flood conditioning parameters such as rainfall, slope, drainage density, land use/land cover, elevation, soil type, geomorphology, topographic wetness index, normalized difference vegetation index and distance from the river using the analytical hierarchy process approach to prepared flood risk zones. The present study determined that a percentage of the area includes high flood risk (1%) and the maximum area is occupied by moderate flood risk zones (67%) flood susceptibility. The result of this study also showing 4% and 28% of the area is under the no risk and low flood risk zones. Accuracy and validation of results of this study under the ROC-AUC curve considerably excellent category (0.909). The output flood risk map can be beneficial for planners, policymakers, government and other private agencies to succeed and mitigate flood events in the Painganga river basin area in the Buldhana district, Maharashtra. The methodology of this study is highly simple and shows high accuracy, it can be applied in other regions for flood risk mapping.
