Altimetric and hypsometric analysis for soil and water conservation: A case study of Anjani and Jhiri river basin, Northern Maharashtra, India. Earth Sci. Res. J. [online]. 2015, vol.19, n.1, pp.51-58. ISSN 1794-6190.  https://doi.org/10.15446/esrj.v19n1.45175.

The present paper contains longitudinal profile, hypsometric analysis of river basin and geomorphological studies for future planning of soil and water conservation in Anjani and Jhiri river basin, Jalgaon district, Maharashtra, India (20°45' to 21°08'N Latitude and 75°09' to 75°27'E Longitude). The main aim of the present study is to recommend a suitable site for soil and water conservation in Anjani and Jhiri river basin, Northern Maharashtra, India. The study area is geologically covered by Deccan trap basalts of the Cretaceous to the lower Eocene age, and some part is covered by thick alluvium of the Quaternary age. Drainage map of the study area reveals two drainage patterns including dendritic and sub dendritic patterns, indicating that the uniform lithology of the basaltic landforms has uniform resistance to erosion. This condition has caused the Anjani and Jhiri River get little recharge from the rainwater and the surface drainage flows during only monsoon season and latter becomes dry. Therefore, water conservation is a prime need for minimize water scarcity problems in the study area. In the present study, landscape information, such as longitudinal profile and hypsometric integral, has been analysed. The longitudinal profile reveals the presence of nick points at three locations in Anjani river and two locations in Jhiri river. The nick points indicate that the rapids are formed due to different erosion, relief and presence of lineament (Joint). The hypsometric integral values for the Anjani and Jhiri river are 0.52 and 0.51, respectively. The present research illustrates that both basins fall under equilibrium stage and are in a mature phase of development.
