Characteristics of typical karst fracture-cave media of a observed region were analysed by means of field investigation. A method of consecutive tests of a variable flow rate was posed according to the characteristics. Consecutive tests were performed by the method combined with a method of consecutive tests of a tracer. Changes of a flow rate and electrical conductivity of water samples with time were determined for observation points. Results show that karst fracture-cave of the region is developed and that groundwater systems and pathways of groundwater flow in the karst fracture-cave media can be determined by the two methods of consecutive tests. The results can provide scientific basis with groundwater resource exploitation and hydraulic & hydropower projects safety assessment in a karst region.
