Hypsometric analysis of basin has generally been used to reveal the stages of geomorphic development. It is estimated by the graphical plot of the measured contour elevation and encompassed area by using empirical formulae. The current research mainly deals with the usingthe hypsometric index to analyzethe hypsometric properties of drainage basins in Sedeh basin. In constructing the hypsometric integral curve, a Digital Elevation Model (DEM) with 30 m spatial resolution has been used. The result of hypsometric curve shows that 6 drainage basins are in Sedeh basin. Three different approaches were used for estimation of hypsometric integrals. The hypsometric integral values (HI) ranges between 0.22 and 0.36 for all the basins of Sedeh basin. In the study area, two stages of erosion cycle development, namely mature and old stages are distinguished. The obtained results of drowned hypsometric integral curves in 6 basins indicate the high value of HI is coincided to fault zones and folds and the southwest of Sedeh basin is more active than other ones.
