The Study Of Hydrogeologic Parameter In Shuangliao City

With the decrease of the flow of DongliaoRiver and Xiliao River,the water resource problem becomes the bottleneck of the development of Shuangliao city in Jilin province.The increasing amount of groundwater resources and the amount of groundwater recoverable resources have become unavoidable problems in the development of Shuangliao City.Hydrogeological parameters play a key role in the evaluation of groundwater resources in Shuangliao City.Therefore,the study of the hydrogeological parameters of Shuangliao City is an important theoretical basis for the evaluation of groundwater resources in Shuangliao City.Based on the topic of the project "Investigation and Evaluation of Groundwater Resources in Shuangliao City",the paper focuses on the study of hydrogeological parameters in Shuangliao City.It focuses on how to calculate and determine hydrogeological parameters,It was based on hydrogeology,and hydrochemical dynamics theory.Using dynamic data analysis,analytical method and hydrochemical dynamics method to calculate the parameters such as specific yield,infiltration coefficient of precipitation,evaporation coefficient,hydraulic conductivity,etc.the following conclusion is obtained:(1)Using the dynamic data analysis method to calculate specific yield,infiltration coefficient of precipitation,evaporation coefficient,Irrigation coefficient.Specific yield of valley and platform:0.030-0.080,0.030-0.060;Infiltration coefficient of precipitation of valley and platform: 0.092-0.249,0.101-0.180;Evaporation coefficient of valley and platform: 0.030-0.092,0.031-0.068;Irrigation coefficient of valley and platform: 0.085-0.097.(2)Using the analytical method to calculate the hydraulic conductivity,influence radius.specific yield.Hydraulic conductivity of valley and platform:15.00-97.00,1.32-10.00;Influence radius.of valley and platform:133.69-679.00,100.00-574.90;Specific yield of valley and platform: 0.100-0.125,0.055-0.080;(3)The hydraulic conductivity of each partition is calculated by the hydrochemical dynamics method.The results are similar to which calculated by the analytical method.Because the hydrogeological conditions reflected by the hydrochemical potential field are consistent with the hydrogeological conditions reflected by the seepage field.Hydrogeological parameters calculated by the hydrochemical dynamics method is consistent with the hydrogeological environment.(4)By comparing and analyzing the advantages and disadvantages of several calculation methods,it is concluded that the full curve fitting method is most suitable for the hydrogeological parameters in Shuangliao City,and the water chemistry method verifies whether the calculation results are reasonable.
