The applied model for this study area is WHPA, WINFLOW and MODPATH using finite element and finite difference method, It is thought that the simulation result by WINFLOW model under the steady flow state reflects well the groundwater distribution within the reliability level which shows the error range of 0.06% to 0.38% from the comparison between the computed values and the observed. Groundwater of the study area shows stable movement from the south to the stream area, and the particle trace for each location shows relatively linear shape from the upstream to the pumping location while the capture zone according to the pumping amount shows a significant difference at the down stream area from the pumping location. The simultaneous pumping from P and P1 on the models shows more complicated appearance, not the increase of the capture zone than pumping from a single well P or P1, and it is analyzed that the particle path takes nearly linear form. It is known that the flow direction of the groundwater and the velocity of the flow affect on the magnitude of the capture zone of the wells from the fact that the more decreasing pattern of the groundwater head is observed at the side of the well and the down stream area than the upstream area when the groundwater moves from south to north regarding the capture zone according to the pumping amount. Satisfactory results in analyses of capture zone on the long period pumping are obtained through the significant reduction of the physical uncertainties in the flow system as well as the relatively convenient model application using WINFLOW and MODPATH model which is proposed in this study.
