Short summary

For accurately reflecting the eco-hydrological process of the dual structure of the surface and subsurface, we propose a new method for the extraction of small watersheds in karst regions. In this study, we think that the minimum karst watershed has an exit at the corrosion–erosion datum, and the further karst sub-watershed division may cause an eco-hydrological fault. The watersheds delineated by our method accurately reflect the hydrological process in the Sancha River.
