The Soil and Water Assessment Tool (SWAT) was used for projection of changes in the hydrological regime of the Kaligandaki basin, based on Representative Concentration Pathways Scenarios (RCP 4.5 and RCP 8.5) of ensemble downscaled Coupled Model Intercomparison Project's (CMIP5) General Circulation Model (GCM) outputs. A rise in the average annual temperature of over 4 °C, and an increase in the average annual precipitation of over 26% is predicted by the end of the 21st century under RCP 8.5 scenario. Modeling results show these will lead to significant changes in the basin's water balance and hydrological regime.
