Unde, M: Flood Risk Analysis of River Godavari

Flooding is a natural and recurring event for a river or stream. The River Godavari is a major drainage system and largest river of the Peninsular India. It originates in the Western Ghats at Bramhagiri near Trimbakeshwar in the Nashik District of Maharashtra at an elevation of 1294 m above sea level. With a total length of 1465 km of which 694 km is in Maharashtra State. The main aim of this study is to find out the areas which are prone to flood risk every year and mark the flood lines in urban flood area. Urbanization is the major cause for the rivers to get flooded and spread the water in to residential areas. Residential areas goes on increasing every year in the flood plain zones and this type of encroachment leads to decrease in channel width and increase in flood prone zones. Floods of 2006 and 2008 were taken for the present studies which have created a great Data have been collected in field and from the different government offices. At the outcome it can be said that the large floods are important geomorphic agents that temporarily affect the forms and behavioral characteristics of some rivers, but leave a lasting effect in urban areas.
