Mapping of Flood Risk Zones of Chandrabhaga River Around the Pilgrim City of Pandharpur by Using Remote Sensing, DEM and GIS Techniques

In the past, there have been severe climatic conditions occurring in most part of the earth due to climate change. As a result of this, the intensity of rainfall has increased tremendously causing flooding in many areas and countries worldwide. Therefore, it is very important to have a thought on such a natural hazard to minimize the impact which it creates on public and environment. In order to prepare from such calamity, vulnerable areas for flood affection need to find out. In flood risk management activity demarcation of flood prone areas plays an important role. Therefore, in this research paper, efforts were made to find out the flood prone areas by using remote sensing, (DEM) digital elevation model data and GIS techniques. LISS III satellite data, Cartosat DEM have been used to generate the slope gradient of the study area. To get the different level of flood risk map, the slope gradient map has been reclassified in low risk, medium risk and high risk zone maps. It is recommended to the people residing in high risk areas to relocate into low risk area.
