Abstract
A practical model for analyzing groundwater flow system to be applicable in field site was developed by reconstructing the Koreanized 3-dimensional finite difference method(DFM) model(ver. 1.1.1 and 1.1.2) with 3-DFM model strengthened a graphic function for post process. The practical model developed in this study was applied to analyses ground flow system in Yangchon area, Sangju, Kyungbook. The WINFLOW model of 2-DFM was used to compare with the practical model. Based on the comparison of observed and computed values of groundwater level in well, the variation range of water level were 0.03m for 3-DFM at P4 well and 0.06m for WINFLOW at P well. The well showed the greatest variation range of water level were the well of P with 0.16m for 3-DFM and the well of P1 with 0.35m for WINFLOW. A relative error of observed and computed values ranged from 0.037 to 0.195% for 3-DFM and 0.073 to 0.419% for WINFLOW. This shows the 3-DFM model is more closer to observed value. Simultaneous pumping of P and P1 wells compared to single well increased the size of radius of influence and showed a little complicated aspect.
