Special Issue Information

Dear Colleagues,

Due to the strong dissolution of groundwater to carbonate rocks, karst caves, underground rivers, and other geological structures are widely developed in karst areas. These phenomena cause extremely complex hydrogeological conditions in karst areas and result in the frequent occurrence of geological disasters such as water inrush, collapse, landslide, and the deterioration of a water environment, which poses a great threat to engineering activities and human living environments. Although it is a challenging task to study the formation mechanism, process assessment, and accurate early warning of hydrogeological disasters in karst areas, it has important practical significance for disaster prevention and control in these areas.

The present Special Issue focuses on the formation mechanism, disaster assessment, and early warning technology of hydrogeological disasters in karst areas. We call for original research papers with a high scientific quality as well as state-of-the-art review articles covering but not limited to the following topics:

  • Occurrence characteristics of groundwater in karst areas;
  • Mechanism and assessment of hydrogeological disasters in karst areas;
  • Hydrogeological disaster information identification and early warning in karst areas;
  • Formation and early warning of water inrush disaster in underground engineering in karst areas;
  • Groundwater environment assessment and early warning in karst areas;
  • Groundwater environment restoration technology in karst areas;
  • Sustainable utilization technology of groundwater resources in karst areas.

Karst groundwater resources are rich, and they have important water supply significance. A karst reservoir is a means of exploiting and utilizing groundwater resources, but because of the complex hydrogeological structure and underground river pipeline in a karst area, the seepage problem of the reservoir is extremely serious. Therefore, the Yibasan Karst Reservoir (YKR) was selected as the focus of this study. The hydrogeological structure of the subterranean river system of Yutang (SRSY) was identified and the hydraulic connections between the subterranean river conduits were determined using tracer experiment and groundwater dynamic monitoring. Furthermore, the development location and depth of the karst seepage zone of the YKR were determined using geophysical exploration. The results showed that there were three subterranean river conduits in the SRSY, and there was no hydraulic connection. The northern and southern pressure and torsion faults on the sides constitute the impervious boundary of the SRSY, which provided good catchment conditions for the formation of the YKR. Additionally, the northern and main conduits of the SRSY provide a sufficient groundwater source for the YKR. Moreover, the development width of the karst seepage zone of the YKR ranges between 40 and 60 m, and the elevation ranges between 1275 and 1355 m. The research results not only provide an effective basis for the treatment of the karst seepage problem of the YKR but also provide an important reference for the development and utilization of groundwater resources in similar karst areas.
