摘要：The determination of flood source area and ranking sub-basins according to flood potential can play an important role in a management of large watersheds. The Hassan-Abad watershed, located in southeast Iran, was chosen for a study of the occurrence of floods. Each sub-basin share in the total watershed flood was established by using GIS and the HEC-HMS based SCS CN method. For this purpose, by successively eliminating sub-basins from the simulation process using a unit flood response method, the contribution of each sub-basin to the outlet flood peak was quantified. Results show that not only sub-basin areas influence their share in the total watershed flood potential, but also factors such as their location and flood routing in the main river are of a great importance. The contribution per unit area to the outlet flood peak was used as the basis to rank the sub-basin in terms of their flood potential.
