英文摘要	Land use/land cover (LULC) change, often a consequence of natural or anthropogenic drivers, plays a decisive role in governing global catchment dynamics, and subsequent impact on regional hydrology. Insight into the complex relationship between the drivers of LULC change and catchment hydrology is of utmost importance to decision makers. Contemplating the dynamic rainfall -runoff response of the Indian catchments, this study proposes an integrated modeling -based approach to identify the drivers and relative contribution to catchment hydrology. The proposed approach was evaluated in the tropical climate Nagavali River Basin (NRB) (9512 km 2 ) of India. The Soil and Water Assessment Tool (SWAT) hydrological model, which uses daily -scale rainfall, temperature, wind speed, relative humidity, solar radiation, and streamflow information was integrated with the Indicators of Hydrologic Alteration (IHA) technique to characterize the plausible changes in the flow regime of the NRB. Subsequently, the Partial Least Squares Regression (PLSR) based modeling analysis was performed to quantify the relative contribution of individual LULC components on the catchment water balance. The outcomes of the study revealed that forest land has been significantly converted to agricultural land (45 - 59%) across the NRB resulting in mean annual streamflow increase of 3.57 m 3 /s during the monsoon season. The affinity between land use class and streamflow revealed that barren land (CN = 83 - 87) exhibits the maximum positive response to streamflow followed by the built-up land (CN = 89 - 91) and fallow land (CN = 88 - 93). The period 1985 - 1995 experienced an increased ET scenario (911 - 1050 mm), while the recent period (2005 - 2020) experienced reduced ET scenario owing to conversion of forest to agricultural land. Certainly, the study endorses adopting the developed methodology for understanding the complex land use and catchment -scale hydrologic interactions across global -scales for early watershed management planning.
