Popis: Flooding is the most prevalent global geo-epidemic, wreaking massive havoc. Five geo-environmental factors viz., slope, geology, geomorphology, soil infiltration capacity, and land-use land-cover were employed to identify the flood-prone zones of the Rangat watershed using remote and GIS. The results of the present study indicate that 0.55 Km2 of the Rangat village is highly vulnerable to flooding during heavy monsoon followed by Dasharatpur village (0.53 Km2 ). 1.98 Km2 of the Rangat river is highly is very prone to seasonal flooding of the total 12.25 Km2 , while 1.04 Km2 is moderately sensitive. With the ever-changing landscape pattern and climate change, the Rangat watershed is more susceptible to monsoonal flooding time and again in the future.
