中国西南岩溶地下河系统旱涝致灾因素模拟分析
Simulation analysis of drought-flood disaster factors for karst underground river system, southwest China
摘要
Abstract
The time and speed of water rising and falling under the impact of different depth,plane distribution shape and hydraulic gradient of underground karst conduit were obtained through lab simulation and response analysis to the same rainfall intensity with various control method.The influence of karst conduit causes leading to drought and flood disasters was analyzed.The results show that the karst underground rivers with shallow-buried,gentle gradient in downstream and dendritic shape karst conduit are sensitive and so there is fast response to the rainfall input.The karst underground rivers with deep-buried,steep gradient in downstream and dendritic shape karst conduit have lower water table in stable discharge period.关键词
