Floods are the most repeatedly occurring destructive natural disaster due to an overflow of water submerging land
which is basically dry. Generally, floods are occurring due to heavy rainfall or cloud bursting or manmade disturbance to
nature, fast snowmelt, global warming or tropical cyclone or tsunami. In 2019, the Krishna River has faced very heavy rainfall
and major floods which took the lives of approximately 500 people and nearly isolating 350 villages and left millions
homeless. Here we studied the previous flood disaster at the basin of the Krishna River and processed the GIS environment using
