Thisresearch is intended to assess the regional pattern of hypsometric curves andhypsometric integrals for the watersheds draining into the Jordan Rift 30 mresolution  = and River Jordan = watersheds. Whereas the lowest values 0.51 lowerWadi Araba 0.41 0.58 which are associated with a balance, or dynamic equilibrium between erosion andtectonic processes. Accordingly, they correspond to a late mature stage ofgeomorphic development. Additionally, Wadi Nukhaileh yields the lowest HI value0.26and is associated with highly eroded terrain of late mature geomorphic evolution,approaching an old stage therefore, with distorted concave upward curves. HighHI values indicate that these watersheds have been subjected to tectonicuplift, down faulting of the Rift and intense rejuvenation. Differences in HIvalues can be attributed to disparity in tectonic uplift rate, base levelheights, and mean heights of the River Jordan watersheds, the Dead Sea and WadiAraba watersheds, and variation in lithology, which caused noticeabledifferences in rejuvenation processes, and channel incision. Regressionanalysis reveals that R2 values which represent the degree ofcontrol of driving parameters on HI, are positive and generally low except for the height of base level parameterwhich contributes 0.42significant at 0.1% level. Such results mean that the height of baselevel has a significant at 0.1% level. It isobvious that the most crucial driving morphometric factor influencing HI valuesof the Jordan Rift drainage basins, is the height of base level
