Abstract The water resource management is a present need for sustaining the living environment on a watershed. The anthropological activities on any watershed cause resources imbalance that eventually affects the watershed performance. Remote sensing and geographical information system are the powerful tools to identify such changes in the watershed either by natural causes and/or by human intervention. Such knowledge is useful for scientific planning and management of watershed. The present study has been highlighted the morphometric analysis with land use and land cover (LULC) changes and hydrologic performance during 2001 and 2011 over the Champua watershed of Upper Baitarani river basin, Odisha, India. The various parameters of morphometry which cause soil erosion have been evaluated and are used to prioritize the sub-watersheds. Also, LULC changes from two satellite imaginaries of the years 2001 and 2011 have been classified and percentage area changes of the respective classes for the sub-watersheds over one decade have been estimated. Then, various land features which would increase runoff and cause more soil erosion have been evaluated to prioritize the sub-watershed. Finally, prioritization is assigned for sub-watersheds, according to severity effects due to morphometric parameter and LULC changes. To archive for management point of view, the conservation practices or measures are recommended as per their final priority. These results obtained from prioritization of sub-watershed would be useful for hydraulic engineers for planning and management.
