基于GMS的云南某大型水库地下水流场变化预测研究

GMS-based prediction of the variation of groundwater flow field of a certain large reservoir in Yunnan

水库的建设会引起库区区域地下水水位和流场的变化,进而引发土壤沼泽化等环境次生灾害,应当给予高度重视。研究基于GMS-MODFLOW软件模块模拟某水库蓄水区的地下水水位和流场变化情况,通过对模型的识别与校正,水库蓄水区流场变化明显。模型模拟和评价的结论可作为判断地下水环境影响的依据,为水库管理提供科学依据和技术参数,指导水库的科学开发。

The construction of reservoirs will cause variations of groundwater level and flow field in its area,and it shall be paid great attention to that soil paludification and other environmental secondary disasters occur easily.The study simulated the variation of groundwater level and flow field of a water storage area in a certain reservoir by using the software module GMS-MODFLOW,and the variation of flow field in the water storage area in the reservoir becomes evident through identification and correction of the model.The simulation by models and the conclusion of evaluation can be used as a basis for judging the impact on the groundwater environment,and can provide a scientific basis and technical parameters for the management of reservoirs for the sake of guiding the scientific development of the reservoir.
