Abstract: A flood is an overflow of water from the river during which water spreads over active and inactive flood plain because of natural and artificial reasons of flooding causing damage to property as well as human lives. In Maharashtra, Pune City, faces problems of floods and damages during monsoon. Many bridges over Rivers get submerged, resulting failure of communication facility, inundation of the city and surrounding area during this period. Maximum flood recorded in Pune city is in the year 2005. Unsteady flood model in HEC-RAS was proposed to be set up using available geometrical and hydraulical data of Mutha River. The Mutha River reach of length 14.905 km is proposed to be simulated from downstream of Khadakwasla dam to Mula –Mutha confluence. The flooding are usually caused by the release of water from the reservoirs located in the Upper reaches of Mula & Mutha Rivers. This paper describes the setting up of hydraulic model In HEC-RAS 5.0 for Mutha River in Study reach. Calibration and validation of hydraulic flood routing model based on the past data of the area under study. By using the developed model, Estimation of hydrograph for Worst scenarios of 75% and 100 % of spillway capacity flood release from Khadakwasla dam.
