Hydrochemical Simulation and Using the Hydrochemical Kinetics to Calculate the Parameters in Longkeng
This paper goes up each node representative sample using PHREEQC software , on the flow line, to carry out the calculation of degree of saturation and the inverse hydrochemical simulation , the chemical type whose result shows of the study district underground water belongs to typical dissolve water. In the entire runoff process, dolomite, gypsum and halite are in not saturation state, calcite is part to reach saturation , gypsum and halite dissolve continuously. Applying the method of groundwater chemical kinetics to calculate the hydrogeology parameter is the synthesize utilizing of the theories of chemical thermodynamics, hydrochemical dynamics and ground-water dynamics. This method can not only remedy the difficulty that is hard to determine hydrogeology parameter because of lacking the information of pumping test and can reduce the work of pumping test , save cost. The infiltration coefficient and velocity that uses chemical dynamics method to calculate show that the permeability of the aquifer in the middle of the study area is higher, in the recharge area is little high, the drainage area is most weak. The cycle time of underground water will take about 90 years.
