2013年美赛B题原文及翻译
PROBLEM B: Water, Water, Everywhere
Fresh water is the limiting constraint for development in much of the world.
Build a mathematical model for determining an effective, feasible, and cost-efficient water strategy for 2013 to meet the projected water needs of [pick one country from the list below] in 20 25, and identify the best water strategy. In particular, your mathematical model must address stora ge and movement;
de-salinization; and conservation. If possible, use your model to discuss the economic, physical, a nd environmental implications of your strategy. Provide a non-technical position paper to governm ental leadership outlining your approach, its feasibility and costs, and why it is the “best water stra tegy choice.”
Countries: United States, China, Russia, Egypt, or Saudi Arabia
国家: 美国、中国、俄罗斯、埃及或沙特阿拉伯
淡水资源是世界很多大部分国家发展的瓶颈。
为2013年建立一个数学模型，来确定一个有效的、可行的和有成本效益的水策略（从下面的列表选择一个国家），以满足2025年的水需求，并且确定最佳的水策略。
特别是,你的数学模型必须解决该国的水资源存储量和流动规律、去盐碱化（海水淡水化处理等）、水资源保护等问题。如果可能的话,用你的模型来讨论你的策略在经济、物理（地理等）和环境等方面的影响。
提供一个非技术立场报告给政府领导概述你的方法,其可行性和成本,以及为什么它是“最好的水策略选择。”
