Assessment of Impacts of Climate Change on Varied River-Flow Regimes of Peninsular India

Objectives: Precipitation is a major component of the hydrological cycle. varies in intensity throughout time and space. The discharge at outlet catchment directly proportional to precipitation received catchment. current research looks as well patterns Sagar Kokkarne catchments Western Ghats Karnataka, India. Methods: In present research, soil water assessment tool (SWAT) has been applied monitor quantify streamflow catchments. analysis for period 2021-2050 both carried out. seasonal yearly were studied using Coordinated Regional Downscaling Experiment-South Asia data RCP 4.5 scenario 2021-2050. Findings: During Southwest monsoon Northeast Monsoon, about 81.44 % 14.22 87.34 6.93 obtained respectively. contribution Monsoon greatest, followed by monsoon. 2021-2050, less than 80 probability expected 23 years more 20 4 years. maximum are 16.96 m3/sec 213.87 Novelty: two different on each side Karnataka compared study understand impact climate change hydrology these regions.
