该文运用GMS的Modflow模块建立研究区域的水文地质模型,并运用PEST模块根据现有观测孔数据优化水文地质参数。根据研究区域三口抽水井数据,利用Aquifertest软件计算水文地质参数。通过GMS优化后的参数与计算所得参数的对比,表明优化后的参数符合模拟区域的实际情况。这种方法的优点在于能够充分把握区域的整体性,自动优化参数。
In this paper, a GMS modflow module is used to establish the hydrogeological model of the study area and the PEST module is used to optimize the hydrogeological parameters based on the data of the existing observation wells. Based on the data from three wells in the study area, Aquifertest software was used to calculate the hydrogeological parameters. The comparison between the GMS-optimized parameters and the calculated parameters shows that the optimized parameters are in accordance with the actual situation in the simulation area. The advantage of this approach is that it takes full advantage of the integrity of the area and automatically optimizes the parameters.
