Abstract: Reliable estimation of design flood is critically important for the design of water resources infrastructure. At sites where the stream flow data is not available for a sufficiently long period of time, frequency analysis cannot be carried out for the estimation of floods with different return periods. A methodology based on hydrometeorlogical approach has been presented for the estimation of design flood at Kol Dam - a major reservoir in the Satluj River Basin. In the absence of concurrent rainfall intensity and stream flow data at the Kol Dam site, Snyder’s method was applied to develop synthetic unit hydrograph. The values of the standard project storm and probable maximum storm required for the computation of ordinates of 2-day probable maximum flood hydrograph, and 2-day standard project hydrograph at the Kol Dam site were based upon the recommendations of the Central Water Commission of India. The peak of the probable maximum flood hydrograph was found to be significantly higher than the peak of the standard project flood hydrograph.
