英文摘要	The present study focused on evaluating the separate and combined response of land use land cover and climate change (CC) on future water balance components of a Subarnarekha River basin, spanning between the latitudes 21 degrees 33'N-23 degrees 18'N and longitudes 85 degrees 11'E-87 degrees 23'E, situated in the eastern India. The Soil and Water Assessment Tool is used for single-site calibration and multi-site calibration(MSC) of the model to characterize the future water balance components of the basin using the Cellular Automata-Markov model and climate projections under two representative concentration pathway (RCP) scenarios (4.5 and 8.5). The findings indicate that the model parameters obtained through MSC better represent spatial heterogeneity, making it the preferred calibration approach for model simulations. In the middle region of the basin, future annual water yield, groundwater recharge (GWR), and streamflow showed a reduction, respectively, by46-47%, 29-30%, and 13-15%, while evapotranspiration showed an increase by 5-7% following projected CC under both RCP scenarios. The findings are relevant for policy-makers to mitigate the adverse effects of reduced GWR for sustainable water resources management. Future research may integrate reservoir operation framework to effectively address the water management issues of the basin.
