Automatic segmentation of karst reservoir CT images and identification of karst spatial structure based on 3D U-Net [PDF]
Sci RepKarst reservoir Computed Tomography (CT) images exhibit blurred boundaries, scale variations, and complex structures. Existing 3D U-Net-based segmentation methods are inadequate in both detail recognition and overall structural representation. Therefore,

Carbonates and Evaporites, 2011 The construction of an underground dam and reservoir to provide an artificial water storage and karst control groundwater discharge regime is one of the most complex systems of tapping structure in karst. There are not many examples of underground dams, which increase the importance of risk management in their construction.

SustainabilityThis study aimed to enhance flood forecasting accuracy in the Liangfeng River basin, a small karst watershed in Southern China, by incorporating the Available Reservoir Capacity of Karst (ARCK) into the HEC-HMS model. This region is often threatened by floods during the rainy season, so an accurate flood forecast can help decision-makers better manage ...
