GMS在团结镇地下水流数值模拟中的应用

Application of GMS in Groundwater Flow Numerical Simulation in Tuanjie Town

利用GMS(groundwater modeling system)软件包中的MODFLOW模块建立哈尔滨市团结镇地区地下水流模型,通过对模型的识别、验证确定该模型的各类参数,并对该地区地下水位进行预报,预报时段至2020年1月1日。利用MATLAB工具将导出的预测数据绘制出该地区的地下水初始水位与预报水位三维等值线对比图。根据研究区域地下水三维等值线图对比图可知:初始水位较高的地区预测出的地下水位与初始水位相比有所下降;初始水位较低的地区预测出的地下水位与初始水位相比有所上升。通过三维等值线对比图可以清晰地看出地下水位的变化趋势。

In this study, the groundwater flow modeling in Tuaniie town o{ Harbin is established by MODFLOW module of GMS software, the groundwater-level in study area is predicted, and the period of predicting is until January 1, 2020. The three dimensional contour figure of groundwater-level in study area are drawn by MTALAB with the predicted data. The results of comparing the corresponding three dimensional figure of initial groundwater-level and predicted groundwater-level can clearly show the variation of groundwater-level in study region. The result shows that the predicted groundwater-level decreases in the area where the initial groundwater-level is lower, while the predicted groundwater-level increases in the area where the initial groundwater-level is higher.
