0412904PiaseckiThis proposal will advance integrative hydrologic science through the development of a hydrologic information system that can be implemented at universities throughout the United States. It involves collaboration between hydrologic scientists from the Consortium of Universities for the Advancement of Hydrologic Science, Inc (CUAHSI) and computer scientists from the San Diego Supercomputer Center, and supports a larger strategy at NSF to develop cyberinfrastructure to advance interdisciplinary study of environmental systems. The CUAHSI Hydrologic Information System will be built around a hydrologic data model that synthesizes data from diverse sources describing the water environment, and will support knowledge discovery through its own analysis and visualization tools and links to external modeling and software systems. The Hydrologic Information System will be built as a network so that data sources from many geographic locations can be automatically harvested and imbedded within a common data framework at the user's location. In this project, a prototype system will be developed with the San Diego Supercomputer Center as the hub, and the experience thus gained used to define a request for proposals for a CUAHSI Center for Hydrologic Information which will be responsible for the long-term maintenance and support of this system.Integrative hydrologic science will be addressed through a series of CUAHSI science driver questions posed first for a hydrologic observatory planning study of the Neuse River Basin, whose data will be synthesized into the CUAHSI hydrologic data model as a prototype Digital Watershed. Similar Digital Watersheds will be constructed using later CUAHSI planning studies for hydrologic observatories elsewhere in the nation, thus providing a comprehensive information base for comparative studies across different hydrologic regimes. These datasets will be made freely available through an internet interface, and the hydrologic data model will also be provided to hydrologic scientists who want to develop Digital Watersheds at other locations.The intellectual merit of this project is that it harnesses information technology to support hydrologic science by building around a data model that has a coherent intellectual structure and synthesizes data from many disciplines. It will enable the tracing of water movement and transport of constituents vertically between atmosphere, surface water and groundwater, and horizontally through the landscape from watersheds and aquifers to streams, rivers, estuaries and bays. It will integrate data across scales of space and time. This will enable the testing of hypotheses about the interfaces between hydrologic processes in a manner and scale that is rarely attempted now. The results of these studies will be published in journal articles and as a series of CUAHSI monographs. The prototype hydrologic information system developed in this project will be of significant value in itself for hydrologic science research and also as a guide to the future long-term implementation of CUAHSI hydrologic information systems. The broader impacts of this project include its networking of hydrologic scientists at many universities who will jointly be contributing and receiving hydrologic information. The CUAHSI hydrologic information system and its accompanying datasets will be developed in the public domain and available to the professional hydrology community and to educators at all levels. As educational exercises using this information are developed by CUAHSI scientists, they will be shared with the broader community through such facilities as the Digital Library for Earth System Education (DLESE).

0412904Piaseckithis提案将通过开发可以在美国大学的大学实施的水文信息系统来推动整合水文科学。 它涉及从大学的发展联盟中的水文科学家之间的合作，以发展水文科学，Inc（CUAHSI）与来自圣地亚哥超级计算机中心的计算机科学家之间的合作，并支持NSF的更大策略，以开发网络基础设施以促进环境系统的跨学科研究。 CUAHSI水文信息系统将围绕一个水文数据模型构建，该模型综合了描述水环境的不同来源的数据，并将通过其自己的分析和可视化工具以及指向外部建模和软件系统的链接来支持知识发现。 水文信息系统将作为网络构建，以便可以在用户位置的通用数据框架中自动收获和嵌入来自许多地理位置的数据源。 在这个项目中，将以圣地亚哥超级计算机中心为中心开发一个原型系统，因此获得的经验用于定义Cuahsi水文信息中心的建议请求，该中心将负责该系统的长期维护和支持，该系统将通过一系列Cuahsi Science poss poss of Hydrolologive来解决该系统。将作为原型数字流域合成为Cuahsi水文数据模型。 类似的数字流域将使用后来针对全国其他地方的水文观测器的Cuahsi规划研究来构建，从而为跨不同水文制度的比较研究提供了全面的信息基础。这些数据集将通过互联网界面免费提供，并且还将向想要在其他位置开发数字流域的水文科学家提供水文数据模型。该项目的智力优点在于，它利用信息技术来支持围绕一个数据模型来支持水文科学，该数据模型具有一致的智力结构并合成许多学科的数据。它将能够在大气，地表水和地下水之间垂直地追踪水运动和成分的运输，以及从流域和含水层到溪流，河流，河口和海湾的景观。它将在空间和时间范围内集成数据。这将使现在很少尝试以一种很少尝试的方式和规模来测试有关水文过程之间接口的假设。 这些研究的结果将发表在期刊文章和一系列Cuahsi专着中。 该项目中开发的原型水文信息系统本身对于水文科学研究本身将具有重要的价值，也将是Cuahsi水文信息系统的未来长期实施的指南。 该项目的更广泛影响包括许多大学的水文科学家网络，他们将共同贡献和接收水文信息。 CUAHSI水文信息系统及其随附的数据集将在公共领域开发，并可供专业水文学社区以及各级教育工作者使用。 随着使用此信息的教育练习是由Cuahsi科学家开发的，将通过诸如“地球系统教育”数字图书馆（DLESE）等设施与更广泛的社区共享。
