Watersheds represent basic hydrological units that control surface water and groundwater recharge as well as sediment transport processes across landscapes. Progressively accelerated manifestations of climate change have altered precipitation, temperature and evapo-transpiration pulse dynamics in ways that combine to create a hydrologically stressful watershed environment. This review article provides a comprehensive evaluation of the effects of climate change on watershed hydrology through the integration of multi-source remote sensing datasets with geographically- informative system (GIS)-based analytical processes and physically-based hydrological modelling methodologies.
The research integrates various satellite platforms (Landsat-8/9, Sentinel-2 and MODIS) to assess land use/land cover (LULC) transitions, normalized difference vegetation index (NDVI) trends, and land surface temperature (LST) anomalies over a representative mid-sized river basin spanning approximately 4,200 km². Shuttle Radar Topography Mission (SRTM) digital elevation model data were employed for watershed morphometric analysis and drainage network delineation, while CMIP6 climate projections under SSP2-4.5 and SSP5-8.5 emission scenarios provided the basis for long-term hydrological forecasting through 2080.
The Soil and Water Assessment Tool (SWAT) was calibrated and validated against observed streamflow records (Nash–Sutcliffe efficiency = 0.83, R² = 0.87), and subsequently applied to assess future runoff, sediment yield, and groundwater recharge under evolving climate conditions. Results indicate a projected increase in surface runoff of 18–34% under SSP5-8.5 by mid-century, accompanied by a 22% reduction in baseflow and an estimated 41% escalation in annual soil erosion rates attributable to vegetation loss and altered storm intensities. NDVI analysis reveals a statistically significant declining trend (p < 0.01) in vegetative greenness across 31% of the watershed area over the past two decades, correlating with documented increases in drought frequency and land degradation. The paper concludes with evidence-based recommendations for integrated watershed management, emphasizing reforestation, check dam construction, and GIS-enabled real-time monitoring systems as priority adaptation interventions.
