Impact of Climate Change on Watershed Response: Representative Concentration Pathways over Delhi Regions

Abstract

The significance of climate change impact on watershed response for Delhi has been made by determining the watershed response corresponding to the meteorological parameters for different future climate scenarios i.e. RCP scenarios around different periods. Impact of climate change was quantified by determining the change in runoff response or change in water balance of the area from base year to the future time periods corresponding to different climate change scenarios. First of all, future climate for the area has been obtained by downscaling of future climatic series generated from CMIP5 data for different climate change scenarios. Climatic data of Delhi for year 2006 has been used as the base period and used for the downscaling of CMIP data. The rainfall statistical downscaling become executed considering SDSM framework along with the freshly established RCP settings against Delhi regime.
