0422868 Cheng描述：该项目支持密西西比大学土木工程系亚历山大Cheng博士和摩洛哥拉巴特穆罕默德五世大学土木工程系Abdelkader Larabi博士的合作项目。 他们提议开展研究，为摩洛哥和其他国家沿海含水层的可持续水管理制定最佳模式。 预期的结果包括在海水入侵的约束下，地下水的最佳开采，更好地管理监测计划和补给评估，以及水资源保护。将使用具有强大求解器的三维有限元法来分析现有数据，如地下水测压头、抽水活动和盐度。将采用地理信息系统和图形用户界面进行前后处理，特别是网格生成和可视化。 将研究盐水侵入、抽水威尔斯附近的上锥、最佳抽水率、人工补给评估及其对环境和社会经济的影响等问题。地下水数值模拟工具和优化模型的组合将用于实现这些目标。摩洛哥南部阿加迪尔的苏斯马萨沿海油田被选为这一综合模式的示范点。由于过度开采地下水以及缺乏自然和人工补给，Souss马萨含水层正遭受来自大西洋的严重盐水入侵。将模拟不同补给位置、抽水调节和最佳抽水率分布的情况，以评估最佳海水入侵控制策略。虽然三维密度相关的盐水入侵计算机模型在过去的十年中成为可用的，他们的使用到目前为止仅限于小规模的含水层研究。该项目将应用这些模型，结合优化工具，地理信息系统和图形用户界面的可视化功能，研究在摩洛哥的区域问题，导致最佳的管理program.Scope和更广泛的影响：沿海淡水资源的可持续利用是一个重要的问题，美国，摩洛哥，以及世界各地的沿海国家。 该项目将增加穆罕默德五世大学学生和教师的教育机会和研究能力。研究成果将有助于保护摩洛哥重要经济地区的水资源。水资源管理者和决策者可以利用开发的工具，更有效地进行规划和决策。所开发的系统可应用于世界各地沿海地区的类似情况。

0422868 ChengDescription: This project supports a cooperative project by the Dr. Alexander Cheng, Department of Civil Engineering, University of Mississippi, University, Mississippi and Dr. Abdelkader Larabi, Department of Civil Engineering, Ecole Mohammadia d'Ingenieures, University Mohamed V, Rabat, Morocco. They propose to conduct research to develop optimal models for sustainable water management in coastal aquifers of Morocco and in other countries. The expected outcomes include the optimal exploitation of groundwater under the constraint of seawater intrusion, better management of monitoring programs and recharge assessment, and water resources protection. A three-dimensional finite element method with a robust solver will be used to analyze available data such as groundwater piezometric head, pumping activities, and salinity concentrations. Geographical Information Systems (GIS) and Graphic User Interface (GUI) will be employed for pre- and post-processing, especially for mesh generation and visualization. Problems involving saltwater intrusion, up coning near pumping wells, optimal pumping rate, artificial recharge assessment, and their environmental and socio-economic impacts, will be studied. A combination of groundwater numerical simulation tools and optimization models will be used to accomplish these objectives. The Souss Massa coastal field in Agadir, south of Morocco, is selected as the demonstration site for this integrated model. The Souss Massa aquifer is suffering serious saltwater intrusion from the Atlantic Ocean due to overexploitation of groundwater and the lack of natural and artificial recharge. Scenarios varying recharge locations, pumping regulation, and optimal pumping rate distribution will be simulated to assess the best seawater intrusion control strategies. Although three-dimensional density dependent saltwater intrusion computer models became available during the last decade, their use so far are limited to small scale aquifer studies. This project will apply these models, combined with the optimization tools, and the GIS and GUI visualization capabilities, to study a regional problem in Morocco, leading to a best management program.Scope and broader Impact: Sustainable use of coastal freshwater resources is an important problem for the US, Morocco, as well as all coastal nations around the world. The project will enhance the education opportunities and research capacity for the students and faculty of the University of Mohamed V. The outcome of the study will help to protect the water resources of a vital economic region of Morocco. Water resources managers and decision makers can utilize the developed tools to conduct their planning and decision making more efficiently. The system developed can be applied to similar situations in coastal regions around the world.
