Application of hydrochemical dynamics to parameter analysis of seepage in karst fractured rock mass

It is well known that the chemical data can help us judging the quality of water, but few people realize that it can also tell us the dynamic conditions of groundwater. Based on the monitoring hydrochemical data of major components, trace elements and hydrogen and oxygen isotopic compositions of various springs and the water from drill hole, this paper discusses the hydrodynamic conditions and the flow system of the karst water at Maoba syncline. And the hydrodynamic parameters such as penetrate coefficient, transmit coefficient, flow velocity and the age of groundwater are given. The principles and methods of hydro-chemistry dynamics are applied in this paper to find a kind of parameter analysis method of seepage in karst fractured rock mass. On the basic of theoretical analysis and practice performed with the experimental model a series of significant conclusions concerning the feasibility and calculating efficiency of the method are summarized. Meanwhile, a contrast of k between hydrochemical dynamics method and other methods such as isotopic and the pumping test is worked out.
