CLIMATE CHANGE IMPACT ASSESSMENT ON STREAM FLOW OF GANJAL RIVER, INDIAAdarsh Singh and Geeta Singh
Hydrological models often predict a changing situation, necessitating further research into models to make water resource management more realistic. This study uses soil and water assessment tool (SWAT) model to analyse the possible effect of climate change on the future streamflow of the Ganjal river watershed. It is located in middle sub-basin of the Narmada River, India. The model was calibrated for 1988-2007 and validated for 2008-2015 using monthly discharge data at the watershed outlet. The calibrated model was then run for the future (2025-52) using climate model output. The study of climate change is completed using the Representative Concentration Pathway scenarios, RCP 4.5 and 8.5 of three different General Circulation Models (GCM). The downscaled output of these GCM from the Coordinated Regional Downscaling Experiment (CORDEX) has been used in this study after bias correction. The findings demonstrate the significance of climate changeâs effect on streamflow.
