Abstract :
Unit Hydrograph (UH) is the most famous and generally utilized technique for analysing and deriving flood hydrograph resulting from a known storm in a basin area. For ungauged catchments, unit hydrograph are derived using either regional unit hydrograph approach. Central Water Commission (CWC) derived the regional unit hydrograph relationships for different sub-zones of India relating to the various unit hydrograph parameters with some prominent physiographic characteristics. The Study Area is located between Latitude 15º57′58′′ N to 16º11′25.6′′ N and 77º18′1′′ E to77º32′5.3′′ E Longitude and covers area of 360.97 km2, having maximum length of 26.17 km. The maximum and minimum elevation of the basin is 533 m and 323 m above MSL, respectively. The Peak discharge of unit hydrograph obtained is 311.469 m3/s. The final cumulative discharge is 1458.55 m3/s.
