Abstract

Envelope curves developed by plotting the largest flood peaks versus the catchment area can be used in estimating peak flood discharges. This study, therefore, provides a basic understanding of the relationship between the basin area and the peak flood. Envelope curve developed for Indus and Jhelum River basins is obtained by using the recent data as well, can be used for the estimation of peak flood discharge that has occurred in the specific region within these catchments and compared with the curve for Danube River basin. This work is also helpful for the improvement of flood frequency analysis at high return periods. Purpose of this work is deriving an upper bounds and to use them in the distribution function. By this approach, the estimation of discharge for higher return periods seems to provide more realistic discharge estimation for higher return periods.
