Abstract: Probalistic estimation of one day maximum runoff is essential for safe and cost effective planning and design of surface runoff storage system. In Present study, One-day maximum and consecutive 2 and 3 day maximum runoff were computed for the Bamhani Watershed. The curve numbers are treated as random variables with the curve numbers associated with antecedent runoff condition II (Normal) representing 50% CN. Those associated with dry and wet are shown to be representative of 10% and 90 % CN value respectively. The design runoff (CN) was estimated for 10-year period by using SCS-CN model. Furthermore, 1, 2, and 3 day maximum runoff was fitted with three probability distribution (Log-normal, Gumble and Log Pearson-III. Of the Three probability distributions employed, Log Pearson type 3 distribution exhibited the best fit for the data. Finally 1, 2, and 3 day maximum runoff was estimated at return periods of 2, 5, 10, 25, 50, 100 and 200 years. The match between the design CN (for dry condition)-generated runoff and the conventional design runoff is found to be satisfactory for all return periods and rain durations for the studied watersheds, indicating the versatility of the proposed approach. © 2013 IEEE.
