Scrutinizing the Hydrological Responses of Chennai, India Using Coupled SWAT-FEM Model under Land Use Land Cover and Climate Change Scenarios

This study implemented a coupled SWAT-FEM simulation model to evaluate the impacts of land use cover and climate change scenarios (LCS) on water resources river catchments in Chennai, India. The data were obtained by merging source from National Remote Sensing Centre (NRSC) International Water Management Institute (IWMI). Climate simulations four global models (GCM), including GFDL Baseline Scenario (1981–2000), A1B (2081–2100), CCSM4 (1986–2005), (2081–2100). LCS predicted temperature increases 2.32 °C 1.74 for CCSM4, respectively, end century. predictions suggested above 20% utilization 2100, inferring noticeable dynamics inter-annual as well inter-month variability basins Chennai soon. is novel through its implementation modeling approach improve practicality deliver useful projections hydrological responses. results provide insights into how conditions alters spatiotemporal responses catchment scales.
