Hypsometric curve and integral estimation of four hilly watersheds of Ramganga river basin using RS and GIS

In this study, hypsometric curve (HC) and hypsometric integral (HI) of Chaukhutia, Bino, Naula and Gagas watersheds located in upper Ramganga River basin, Uttarakhand State, India, was done using Remote Sensing (RS) and Geographical Information System (GIS). The results of analysis revealed that the HI = 0.398, 0.345, 0.372 and 0.319 for Chaukhutia, Bino, Naula and Gagas watersheds, respectively. Based on HC two geological stages of erosion cycle i.e. monadnock and mature were identified in the study area. Therefore, the findings of this research could be useful for planning and constructing soil and water conservation structures at appropriate locations in these watersheds.
