Calculation and comparative analysis on hydrogeological parameters in Urad Front Banne

Based on the pumping test data of Xinan town, Urad Front Banner of Bayinnaoer city in Inner Mongolia Autonomous Region, four methods such as Theis type curve method, straight line method, water level recovery method and whole curve matching method are used to determine the hydrogeological parameters. The results are compared with each other and it shows the Whole Curve Matching Method (WCMM) is relatively reasonable and reliable. The whole data of pumping and water level recovery period are considered for WCMM and type curve fits measured curve, the least square method is used to control the fitting results. The results show that the WCMM is an effective method to determine hydrogeological parameters.
