U.S.-Indonesia Cooperative Research: A Quasi-Three Dimensional Groundwater Optimization Model of the Jakarta Basin

该提案要求资金允许博士。洪堡州立大学环境资源工程系的Brad a . Finney和Robert Willis将与印度尼西亚万隆理工学院的Idris Maxdoni Kamil教授以及雅加达技术评估和应用机构的科学家/工程师进行为期24个月的合作，开发雅加达地下水盆地准三维地下水优化模型的合作研究项目。该优化模型将用于(1)确定抽水和补给计划，以满足水目标并控制盐度入侵；(2)确定与盆地额外地下水开发相关的成本和环境权衡。本研究将探索使用拟线性化、投影拉格朗日方法和微分动态规划方法求解最优控制模型。印尼科学家将负责开发该盆地的地下水数据库和地下水监测项目。美国科学家将开发雅加达含水层系统的离散时间最优控制模型。印度尼西亚首都和最大城市雅加达的主要供水是地下水，为该地区650万居民提供了80%以上的日常用水需求。过去十年来，该地区地下水的过度开发造成了雅加达沿海平原浅层含水层的水位下降和水质退化。该研究将为该系统的优化管理开发新的技术和工具，并将用于研究大规模地下水优化模型的现场性能。合作者是本研究领域备受尊敬的科学家。目前的项目将使他们能够结合他们的才能和兴趣，互惠互利。该项目与“发展中国家科学项目”的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美国科学家和工程师与发展中国家同行之间的合作水平。

This proposal requests funds to permit Drs. Brad A. Finney, and Robert Willis, Department of Environmental Resources Engineering, Humboldt State University, to pursue with Professor Idris Maxdoni Kamil, Institute of Technology, Bandung, Indonesia, and scientists/engineers at BPPT (Agency for the Assessment and Application of Technology), Jakarta, for a period of 24 months, a program of cooperative research to develop a quasi-three dimensional ground water optimization model of the Jakarta groundwater basin. The optimization model will be used to (1) identify pumping and recharge schedules to satisfy water targets and control salinity intrusion and (2) determine the cost and environmental trade-offs associated with additional ground water development in the basin. The research will explore the use of quasilinearization, projected Lagrangian methods, and differential dynamic programming methods for solution of the optimal control model. The Indonesian scientists will be responsible for the development of a ground water data base for the basin and a ground water monitoring program. The U.S. scientists will develop a discrete time optimal control model of the Jakarta aquifer system. The principal water supply of Jakarta, Indonesia's capital and largest city, is ground water which provides more than 80% of the daily water demand for the region's 6.5 million residents. The overdevelopment of ground water in this region over the past decade has produced declining water levels and degraded the water quality of shallow aquifers in the Jakarta coastal plain. The research will develop new techniques and tools for the optimal management of the system and will be used to investigate the field performance of a large scale ground water optimization model. The collaborators are highly respected scientists in the field of this research. The present project will allow them to combine their talents and interests for mutual benefit. This project is relevant to the objectives of the Science in Developing Countries Program which seeks to increase the level of cooperation between U.S. scientists and engineers and their counterparts in developing countries through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.
