Understanding the impact of human activities on regional water resources is essential for sustainable basin management. This study examines long-term terrestrial storage anomalies (TWSA) in Three Gorges Reservoir Area (TGRA) over two decades, from 2003 to 2023. The analysis utilizes data Gravity Recovery and Climate Experiment (GRACE) its successor mission (GRACE-FO), complemented by Global Land Data Assimilation System (GLDAS) models ECMWF Reanalysis v5 (ERA5) datasets. research methodically explores comparative contributions natural factors region’s hydrological dynamics.

It also reveals pivotal role Dam (TGD) mitigating these events managing resources.

The hydrological cycle in the Tibetan Plateau is experiencing notable changes recent decades under a changing climate. changes, however, are not well investigated due to limitations availability of ground-based observations. In this study, by incorporating satellite-based observations into modeling framework, seasonal and inter-annual dynamics water balance for lakes northwest examined systematically period 1990 2022. Satellite-based observations, including lake area level, have been used calibrate model estimate storage. performs satisfactorily, with Nash–Sutcliffe efficiency coefficient (NSE) exceeding 0.5 all 15 studied lakes. It found that inflow contributes over 70% annual gain most lakes, while percolation accounts larger portion (>60%) total loss than evaporation. expanded substantially, regional average increasing rates level storage 0.38 m/a 3.12 × 108 m3/a, respectively. Some transitioned from shrinking expanding around 1999, expansion has further accelerated since 2012, primarily because increased precipitation catchments, leading greater These findings provide important insights understanding predicting responses climate change as developing adaptative strategies.
