Abstract
In this research the Koreanized 3-DFM model(ver. 1.1.1) has been designed to establish the program mentioned above, and 3-DFM(ver. 1.1.2) is reconstructed that equipped with strengthened graphic function for post processes. All the input data settings of the 3-DFM model which is developed in this study are organized in Korean, and the model contains help function for each input data. Thus, it is designed to get detailed information about each input parameter when the mouse pointer is placed on the corresponding input parameter. This model also is designed to easily specify the geologic boundary condition for each stratum or initial head data in the work sheet. In addition, this model is designed to display boxes for input parameter writing for each analysis condition so that the setting for each parameter is not so complicated as existing MODFLOW is when steady and unsteady flow analysis are performed as well as the analysis for the characteristics of each stratum. Descriptions for input data are displayed on the right side of the window while the analysis results are displayed on the left side as well as the TXT file for this results is available to see. The model developed in this study is a numerical model using finite differential method, and the applicability of the model was examined by comparing and analyzing observed and simulated groundwater heads computed by the application of real recharge amount and the estimation of parameters. The 3-DFM model is applied in this study to Sehwa-ri, and Songdang-ri area, Jeju, Korea for analysis of groundwater flow system according to pumping, and obtained the results that the observed and computed groundwater head were almost in accordance with each other showing the range of 0.03-0.07 error percent. 3-DFM(ver. 1.1.2) model in this research, strengthened the graphic (post processes) functions, needs to set precise helps of input parameters and output values for the people in charge to conveniently apply the model to the site. Therefore it is thought that there are many things to be improved through collecting various data, and that such defects should be given priority to be complemented an dimproved in the future.
