Description
Summary:碩士 === 國立中正大學 === 地震研究所暨應用地球物理研究所 === 95 === This study is to make a new conceptual model, called ‘Solid model’ and run the numerical modeling on Chou-Shui Alluvial Fan with MODFLOW-2000 using the new data from the Central Geologic Survey MOEA(1999). The initial model in this study does not take recharging, pumping, drains, evapotranspiration and so on into consideration. So the results of the initial model just show the characteristics of the rocks in each layer. For example, the hydraulic conductivity in the gravel layer is higher than that in the clay layer, and its gradient of head is lower. Compared with the true situation, it’s shown that the initial model needs corrections. Two corrections are in this study. One is to build some ideal wells with each fixed flow rate in the middle and western areas of Chou-Shui Alluvial Fan. The other is to set up three recharge areas with each fixed recharge rate in the eastern areas of Chou-Shui Alluvial Fan. The corrections are completed comparing to the real head lines in space and to the other models, the layer-by-layer models, from prior studies. The initial results and its corrections verify that it is proper to model some situations of groundwater in Chou-Shui Alluvial Fan using the model in this study. Estimation and evaluation of the flowing groundwater is the other advantage of this solid model.
