本文利用情景模拟评估了盐化沿海含水层的修复潜力。因此,数值模型 OpenGeoSysis 首先根据分析和实验数据进行验证,以代表瞬时地下水位发展和变密度盐水入侵。然后,对具有三维、异质水文地质的区域尺度模型进行瞬态校准,并用于模拟最佳情况。水平衡在瞬态校准和场景运行中进行评估。可视化技术有助于评估复杂的模型输出,为发生的密度驱动的流动过程提供有价值的见解。此外,建模和可视化结果提供了有关修复活动的时间尺度的信息,并且由于数据质量和数量的限制,揭示了模型改进的潜力。
This paper evaluates the remediation potential of a salinized coastal aquifer by utilizing a scenario simulation. Therefore, the numerical modelOpenGeoSysis first validated against analytical and experimental data to represent transient groundwater level development and variable density saline intrusion. Afterwards, a regional scale model with a three-dimensional, heterogeneous hydrogeology is calibrated for a transient state and used to simulate a best-case scenario. Water balances are evaluated in both the transient calibration and scenario run. Visualization techniques help to assess the complex model output providing valuable insight in the occurring density-driven flow processes. Furthermore, modeling and visualization results give information on the time scale for remediation activities and, due to limitations in data quality and quantity reveal potential for model improvement.
