Abstract—The Sina Kolegaon Project in Maharashtra, India is an earthen dam with central Masonry spillway. It has total length of 1612.2m, maximum height of earthen portion is 15.64m and in masonry portion is 26.10m. The project is constructed on the river Sina, a tributary of river Bhima in Krishna basin. The river Sina originates in Ahmednagar district and joins river Bhima in Solapur district. It flows through a considerably flat terrain and has a very mild slope. The catchment area of the river up to dam site is 5569sq.km. The annual rainfall in the catchments varies from 500mm to 700mm. After completion of project there is change in downstream floods (pattern, frequency, severity). There is fear on banks of river on d/s project is “the project created flood situations in dry area” which is not true. It is necessary to determine peak discharges for various conditions, time to reach peaks at various locations and its inundation. In present paper it showed how the flood waves are transmitted on downstream of project for PMF, gate opening hydrograph and various dam breaks. The flood hydrographs at various locations are determined and time to reach the peaks is worked out. Also inundations due to these peaks are worked out. This is very useful data in emergency action plan and preparedness in floods.
