美国高中生数学建模竞赛HIMCM2009试题

旭发飘扬

Problem A: Water, Water Everywhere
Fresh water is the limiting constraint for development in much of the United States.
Devise an effective, feasible, and cost-efficient national water strategy for 2010 to meet
the projected needs of the United States in 2025. In particular, address storage and
movement, de-salinization, and conservation as some of the possible components of your
strategy. Consider economic, physical, cultural, and environmental effects. Provide a
position ** for the United States Congress outlining your approach, its costs, and why
it is the best choice for the nation.


Problem B: Tsunami ("Wipe Out!")
Recent events have reminded us about the devastating effects of distant or underwater
earthquakes. Build a model that compares the devastation of various-sized earthquakes
and their resulting Tsunamis on the following cities: San Francisco, CA; Hilo, HI; New
Orleans, LA; Charleston, SC; New York, NY; Boston, MA; and any city of your choice.
Prepare an article for the local news** that explains what you discovered in your
model about one of these cities.

Problem A: Water, Water Everywhere
水，到处都关水的事儿

Fresh water is the limiting constraint（约束，**） for development in much of the United States.

(1) Devise（设计） an effective, feasible（可行的）, and cost-efficient national water strategy for 2010 - to meet the projected（预计的） needs of the United States in 2025. In particular, address（提出） storage（储存） and movement, de-salinization（去盐碱化）, and conservation（对自然环境的保护） as some of the possible components（组成部分） of your strategy. Consider economic, physical, cultural, and environmental effects.

(2) Provide a position ** for the United States Congress - outlining（概述） your approach, its costs, and why it is the best choice for the nation.


淡水使美国在很多方面的发展中都受到了**和约束。

(1) 制订有效、可行、具有成本效益的2010年全国水资源战略，以满足2025年美国预计的需求。尤其是，要提出存储和变化、去盐碱化和环境保护，作为你战略中一些适当的组成部分。考虑经济、自然、文化和环境的影响。

(2) 撰写一份美国国会的立场文件，阐述你的方法、其成本、以及为什么它是全国最好的选择。


Problem B: Tsunami ("Wipe Out!")
海啸（“毁灭！”）

Recent events have reminded us about the devastating（毁灭性的） effects of distant（遥远的） or underwater earthquakes.

(1) Build a model that compares the devastation of various-sized earthquakes and their resulting Tsunamis on the following cities:

San Francisco, CA; Hilo, HI; New Orleans, LA; Charleston, SC; New York, NY; Boston, MA; and any city of your choice.

(2) Prepare an article for the local news** that explains what you discovered in your model about one of these cities.


最近发生的事件，警示我们想起了，对遥远的或海底地震造成的破坏性的影响。

(1) 建立了一个模型，比较各种破坏性和规模不一的地震，以及其在以下城市引发的海啸——①旧金山（加州）；②希洛（夏威夷）；③新奥尔良（洛杉矶）；④查尔斯顿（南卡罗来纳州）；⑤纽约（纽约州）；⑥波士顿（马萨诸塞州），和⑦您所选择的一些城市。

(2) 就这些城市中其一，为当地报纸拟订一篇文章，阐述您在模型中发现的关于该地的情况。

正在K B题中……纠结……海啸模型很复杂……城市模型更复杂……
