The Three Gorges Reservoir (TGR), a landmark of human engineering, has significantly altered the hydrodynamics and ecology its surrounding environment. Our research explores hydrodynamic ecological changes in TGR, focusing on their implications for reservoir-induced water quality resource issues. We designed 2D model implemented 15 operational scenarios with an advanced dynamic storage capacity method TGR during flood season, drawdown impoundment periods. simulations well reproduced predicted levels, discharge rates, thermal conditions providing critical insights. improved precision level simulations. This approach achieved modeling errors below 0.2 m when compared to real measurements from seven stations. performed detailed analysis sensitive, sub-sensitive, insensitive areas three reservoir operation period showed most extensive impact range (468 km river channel), while had least (76 channel). Furthermore, we quantified delay temperature waves these periods, observing maximum approximately 120 minimum less than 10 km, which underscores variability responses under different scenarios. findings reveal complex sensitivities varied modes, aiding development eutrophication resources control strategies. application provides insights management strategies large dam systems globally, informing future policy-making, ensuring sustainable effective systems.
