Computing for Sustainable Water



Information about this project is provided on the web pages below and by the project scientists on the Computing for Sustainable Water website. If you have comments or questions about this project, please visit the Computing for Sustainable Water forum.

Mission
The mission of the Computing for Sustainable Water project is to study the effects of human activity on a large watershed and gain deeper insights into what actions can lead to restoration, health and sustainability of this important water resource. The extensive computing power of World Community Grid will be used to perform millions of computer simulations to better understand the effects that result from a variety of human activity patterns in the Chesapeake Bay area. The researchers hope to be able to apply what is learned from this project across the globe to other regions which face challenges of sustainable water.

Significance
Water is the most abundant resource on Earth, yet the world faces many challenging water-related problems. Among them is the management of its freshwater resources. More than 1.2 billion people lack access to clean, safe water. This problem is becoming more critical in the world as the proportion of people living in dense urban environments rises. The resulting demands for water contend with increasing human activities which degrade the quality of available water. A complex set of interrelated forces makes the problem difficult to address, much less to solve effectively via coordinated policy.

Approach
The University of Virginia developed a participatory simulation model of the Chesapeake Bay, the UVa Bay Game® (www.virginia.edu/baygame), incorporating natural elements and human activity using game players representing crop farmers, land developers, watermen, and assorted regulators. The UVa Bay Game has been successful in providing a learning platform for conveying the issues of complex watershed behavior and management. But to better understand the complex natural and human dynamics at work in this complex system, a much more detailed simulation model was developed to run on World Community Grid. Each of many millions of computer simulations, using unique combinations of a wide variety of assumptions about the natural and human actions at play, will calculate the resulting effects on the watershed. Exploring these many results, the researchers expect to develop insight into how these assumptions affect the overall health of the Chesapeake Bay. With these insights, the researchers will be able to better inform policy makers and suggest how prudent actions can lead to water restoration and sustainability. The ultimate goal is to eventually apply this knowledge and the techniques learned with the Computing for Sustainable Water project to other watersheds around the world.

為可持續發展水利的計算



下面通過計算水資源可持續網站上的項目科學家在網頁上提供關於這個項目的信息。如果你有關於這個項目的意見或問題，請訪問可持續水資源論壇的計算。

使命
水資源可持續項目的計算任務是研究大流域人類活動的影響，並獲得更深入的見解，到什麼樣的行動可能導致恢復，健康和可持續發展這一重要的水資源。 World Community Grid的廣泛的計算能力將被用來執行以百萬計的計算機模擬的影響，以更好地了解，從各種人類活動的模式，在切薩皮克灣地區的結果。研究人員希望能夠申請什麼據悉，這個項目從遍布全球的其他地區所面臨挑戰的可持續水。

意義
水是地球上最豐富的資源，但世界面臨許多挑戰與水有關的問題。其中之一是其淡水資源的管理。超過1.2億人無法獲得乾淨，安全的水。這個問題正在成為更多的人居住在人口密集的城市環境上升的比例在世界的關鍵。對水的需求抗衡，隨著人類活動，降低現有水資源的質量。使問題難以解決，更談不上通過協調一致的政策，有效地解決一個複雜的相互關聯的勢力。

途徑
弗吉尼亞大學的參與制定了切薩皮克灣的UVA灣遊戲®（www.virginia.edu / baygame）仿真模型，結合自然要素和人類活動的遊戲玩家代表作物的農民，土地開發，船夫，各種監管。弗吉尼亞灣的比賽已成功地傳達複雜的分水嶺行為和管理問題提供了一個學習的平台。但是在這個複雜的系統工作更好地了解複雜的自然和人類動力學，更詳細的仿真模型，開發了世界共同體網格上運行。每個數以百萬計的計算機模擬，獨特的組合使用各種各樣的發揮自然和人類行為的假設，將計算對流域產生的影響。探索其中許多成果，研究人員希望了解這些假設如何影響切薩皮克灣的整體健康發展。這些觀點，研究人員將能夠更好地向決策者和建議如何謹慎行動可能導致水體修復和可持續性。最終的目標是最終申請這方面的知識和技術學會與世界各地的其他流域的水資源可持續項目計算。
