System of Groundwater Flow in Multilayer Pore-Fissure Media with Weak Permeability Layer

Abstract:

Groundwater in pores and fractures of rock can result in destruction of a reservoir dam. Therefore, techniques of forecasting characteristics of groundwater flow have wide applications in areas of hydraulic engineering. A consecutive experiment was designed and combined with analyses of groundwater chemistry to solve a groundwater hydrology problem in multilayer pore-fissure media with weak permeability layer occurring in hydraulic engineering construction in China. Results show that changes of electrical conductivity of groundwater samples from wells, springs and drillings with time have a good relevance except a sample in local position with very weak permeability layer; and that a system and pathways of groundwater flow in multilayer pore-fissure rock with weak permeability media can be determined by the method of a consecutive test combined with groundwater chemistry analyses.
