초록

In this study, GMS-MODFLOW model and GMS-MODPATH model were used to test the groundwater flow interpretation, and a model was designed to reflect the layer and elevation of the target area by separating the layer structure of the target area to identify the characteristics of the underground water flow and the stable water quantity calculation. In the results of analyzing the non-flowing underground water, the highest water head appeared to be 13.4m, in the land, and the lowest water head was 0.7m in the coastal areas, and the flow vectors were from the highest point to the lowest which was from the land to the coastal areas. In the results of changing the maximum yield quantity, by well, from 1,000, 2,400, 5,000, and 7,500, it is shown that the oval shape capture section changes into the circle shape along with the increase of the maximum yield quantity which affects the coastal area. In addition, a 500 pump session was performed a total of 3 times every 60day during an annual stress period to analyze the changes in the water head. In the result, the water level was decreased by 1.4m after the first session, after which 0.2m was recovered after 50day. During the second pump session, 1.7m was decreased but after 50day, 0.1m was recovered and a total of 2.0m was decreased. From 40day later, the water head was recovered by 0.2m, and has quickly recovered to 1.0m since then.
