Short summary
The Three Gorges Dam (TGD)'s impact on downstream groundwater dynamics remains poorly understood. We established monitoring profiles in the first downstream river-lake wetland to spatially quantify groundwater response for the first time. With numerical simulation, how each operation period affects hyporheic exchange is deeply studied. We found TGD suppresses river-aquifer exchange, particularly during dry-season. These findings provide critical insights into dam effects on watershed hydrology.
