| 摘 要： | 在建立水文地质概念模型的基础上,运用FEFLOW软件建立珠江口东岸地区海水入侵三维溶质模型,并利用研究区水位和水质的动态观测资料对模型进行识别和校正。运用模型进行情景模拟,预测现状开采条件下地下水的水质演化趋势。预测2010年,第四系含水层海水入侵面积为115.98km2,基岩裂隙含水层海水入侵面积为89.36km2,2020年,第四系含水层海水入侵面积为106.83km2,基岩裂隙含水层海水入侵面积为82.76km2。预测结果表明:在现状开采条件下,第四系和基岩裂隙含水层海水入侵程度有所缓解,海水入侵面积逐渐减少,Cl-高浓度区域逐渐变小。

| Abstract: | Seawater intrusion in the costal regions of South China has severely deteriorated fresh water quality with the increase of groundwater pumping. Based on the hydrological conceptual model,a three-dimensional flow and mass transport model is developed to study the salt water intrusion in coastal zone of the eastern Pearl River Estuary with FEFLOW software. The parameters of model are estimated by converging long-term observation data of hydraulic head and chloride concentration. The tendencies of salt water i... |
