Abstract: Floods are plausibly the most revenant, far-flung, disastrous, and frequent natural hazards of the world. India is one of the worst flood-affected countries. The problem of flood in the Indian state called Odisha is well known and every year it becomes a recurring problem to the entire region. This paper is centred towards the Subarnarekha River which is an inter-state river and at the South of Dantan it enters the Balasore district and finally falls into the Bay of Bengal near Kirtania, Odisha. However, it is also among the most susceptible areas in India which are prone to flooding. Flood forecasting & flood warning, flood hazard mapping and flood risk zoning are quite effective non-structural procedures in managing floods that decreases the risks and disasters floods may cause. This study introduces the parameterization of hydrologic modelling for simulation of runoff and Arc GIS software for mapping. Various analysis of hydrological data has been done to look for the rainfall and runoff behaviour in Subarnarekha Basin and their cross-correlation. With the help of GIS, various maps like digital elevation map, flow accumulation map and land use/land cover map have been generated for further modelling.
