| Abstract: | Unit Hydrograph (UH) is the most popular and widely used method for analysing and deriving flood hydrograph resulting from a known storm in a basin area. Traditional techniques for design flood estimation use historical rainfall-runoff data for unit hydrograph derivation. 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. In this study, the lately developed UH model is applied to Haridra river catchment located between Latitude 14º07′12′′ N to 14º31′12′′ N Latitude and 75º41′24′′ E to76º13′12′′ E Longitude. The study area covers an area of 1422.77 km2, having maximum length of 85.03 km. The maximum and minimum elevation of the basin is 525 m and 900 m above MSL, respectively. The Peak discharge of unit hydrograph obtained is 199.19 m3/sec. The final cumulative discharge is 4241.19 m3/sec. From this study drainage network analysis and application of the UH can provide a significant contribution towards flood management program. Thus, the present model could be applied to simulate flood hydrographs for the catchments that have not been studied yet. Using very limited data makes this model very useful for ungauged catchments. |
