Short summary
Climate change is rapidly altering Himalayan glaciers, affecting water resources. This study investigates the impact of changing air temperature, precipitation, and glacier configuration on streamflow in the Langtang River basin using a process-based glacio-hydrological model and bias-corrected reanalysis data. Results show increased runoff with current glacier conditions but decreased total streamflow under future deglaciation scenarios, emphasizing the need for adaptation strategies.
