Investigating the Impact of Climate Change on Future Runoff of River Satluj

Abstract

Climate change has been emerging as one of the challenges in the global environment. Information of predicted climatic changes in basin scale is highly useful to know the future climatic condition in the basin that ultimately becomes helpful to carry out planning and management of the water resources available in the basin. Climatic scenario is a plausible and often simplified representation of the future climate, based on an internally consistent set of climatological relationships that has been constructed for explicit use in investigating the potential consequences of anthropogenic climate change. This study based on statistical downscaling, provide good example focusing on predicting the rainfall and runoff patterns, using the coarse general circulation model (GCM) outputs. The outputs of the GCMs are utilized to study the impact of climate change on water resources. The present study has been taken up to identify the climate change scenarios for Satluj river basin, India.Journal of Hydrology and Meteorology, Vol. 8(1) p.10-21

Study of Climate Change using GCM Downscaling: Special Reference to Indian Subcontinent

“…Ghosh and Mujumdar (2007) Figure 1: Illustrating the general approach to downscaling (Wilby and Dawson 2007) decreasing trend in monsoon stream flow of Mahanadi. Gautam et al (2012) performed statistical downscaling of GCM outputs for predicting the rainfall and runoff patterns in Satluj River basin, India. They have projected the future rainfall of 2030, 2050 and 2080 and found that the future rainfall will highly decrease for winter season compared to other seasons.…”
