The groundwater system in the Dongting Lake Plain, central-south China, was investigated from the perspective of tectonics. As a typical tectonic basin, the Dongting Lake Basin has a complex basement topography shaped by a series of tectonic events since the Cretaceous, which presents a vast depression basin with four extensive uplifts scattered in the plain. The barrier effects of the tectonic uplifts on the groundwater system were inferred based on the basement topographic map and Darcy’s law. They were also validated with the spatial analys...
