- Abstract:
-
Both the disappearance of river and underground river are underground currents and the similar modern landscape. Though both of them drain in form of underground-flowing river exit, they are the different Karst hydrogeological phenomenon. Disappearance of river is the disappearance part of river in karst area while the underground river is the underground pipes with the main characteristics of river in karst area. They usually do not distinguish strictly in production and living and the only study about them is limited to the concepts, rarely studying about their characteristic differences. This paper analyzed 6 characteristics of 14 disappearance of river and 24 underground river, including the elevation of exit, stratum, structure, river system, water chemistry and space distribution. Based on the statistical results, there are large differences between them, especially in the elevation of exit, structure, river system, water chemistry and space distribution. Then this paper analyzes the reason for the existence of the differences. This result is helpful for maintaining the ecological environment balance, developing and making use of water resources effectively.
