This proposal advances 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 represented through the Consortium of Universities for the Advancement of Hydrologic Science, Inc (CUAHSI), and computer scientists from the San Diego Supercomputer Center. This proposal supports a larger strategy at NSF to develop cyberinfrastructure for the environmental and earth sciences. The CUAHSI Hydrologic Information System (HIS) is a geographically distributed network of hydrologic data sources and functions that are integrated using web services so that they function as a connected whole. We call this information stream WaterOneFlow, since it integrates the national water data archives with locally published hydrologic data, and makes them directly accessible to hydrologic scientists, almost as if the data were located on a local disk drive. WaterOneFlow is not limited to data scientific workflow systems are used to modularize hydrologic models, enabling them to be published as web services, included in processing sequences, and operated remotely as information sources. This combination of scientific workflows and web services can revolutionize hydrologic modeling. Thus, a distributed network of hydrologic data and models are connected across the internet and collectively support the advancement of hydrologic science and education.The intellectual merit of this project is that it harnesses information technology to support hydrologic science by building an information model that has a coherent intellectual structure and synthesizes data from many disciplines and data sources. This information model forms the basis for a distributed service-oriented hydrologic information system that has been prototyped in HIS Phase 1 and will be developed in this renewal project, HIS Phase 2. This system enables the tracing of water movement and transport of constituents vertically between the atmosphere, surface water and groundwater, and horizontally through the landscape from watersheds and aquifers to streams, rivers, estuaries and bays. It integrates data across scales of space and time. HIS will enable the testing of hypotheses about the interfaces between hydrologic processes in a manner and scale that is rarely attempted now, and based on more information than has been previously possible. CUAHSI has identified this as a central challenge facing hydrologic science. This effort also represents an intellectual investment into the merging of hydrologic science domain expertise with cyberinfrastructure technology knowledge.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. The hydrologic information system developed in this project is significant for hydrologic science and also in showing how cyberinfrastructure is developed for earth and environmental sciences. Related NSF Environmental Observatory initiatives including OOI/ORION, NEON, LTER, and CLEANER are closely following the cyberinfrastructure developments of the CUAHSI HIS group. Moreover, the goal of uniting the nation's water information has wide value for water management, engineering and planning, and the CUAHSI HIS is a means of helping the data delivery services of the Federal water agencies live up to their full potential. The project also includes a partnership with the Navajo Nation water resources program to help integrate and publish their water information. In the computer industry, CUAHSI HIS has received attention as an example of building distributed information systems that integrate scientific principles for helping better manage our nation.

这项建议通过开发可在全美大学实施的水文信息系统来推进综合水文科学。它涉及通过大学水文科学促进联盟(CUAHSI)代表的水文科学家和圣地亚哥超级计算机中心的计算机科学家之间的合作。这项提案支持美国国家科学基金会的一项更大战略，即为环境和地球科学发展网络基础设施。CUAHSI水文信息系统(HIS)是一个地理上分布的水文数据源和功能的网络，这些资源和功能使用Web服务进行集成，以便它们作为一个相互连接的整体发挥作用。我们称这个信息流为Water OneFlow，因为它将国家水数据档案与当地发布的水文数据整合在一起，使水文科学家能够直接访问它们，几乎就像数据位于本地磁盘驱动器上一样。Water OneFlow不仅限于数据，还利用科学工作流系统将水文模型模块化，使其能够作为网络服务发布，包括在处理序列中，并作为信息源远程操作。科学工作流程和Web服务的这种结合可以彻底改变水文建模。因此，一个分布式的水文数据和模型网络通过互联网连接在一起，共同支持水文科学和教育的进步。该项目的智力优势在于，它利用信息技术支持水文科学，通过建立一个具有连贯知识结构的信息模型，综合来自多个学科和数据源的数据。该信息模型构成了分布式面向服务的水文信息系统的基础，该系统已在HIS第一阶段中形成原型，并将在HIS第二阶段这个更新项目中开发。该系统能够跟踪水在大气、地表水和地下水之间的垂直移动和输送，以及从流域和含水层到小溪、河流、河口和海湾的水平移动和输送。它集成了跨越空间和时间尺度的数据。HIS将能够以一种现在很少尝试的方式和规模测试关于水文过程之间的界面的假设，并基于比以前可能的更多的信息。CUAHSI已将此确定为水文科学面临的核心挑战。这一努力也代表着对将水文科学领域的专业知识与网络基础设施技术知识相结合的智力投资。该项目的更广泛影响包括将许多大学的水文科学家联网，他们将共同贡献和接受水文信息。将在公共领域开发CUAHSI水文信息系统及其附带的数据集，供专业水文界和各级教育工作者使用。该项目开发的水文信息系统对水文科学具有重要意义，也有助于展示如何为地球科学和环境科学发展网络基础设施。NSF环境观测站的相关倡议，包括OOI/Orion、NEON、LTER和CLEAN，正在密切关注CUAHSI HIS小组的网络基础设施发展。此外，统一全国水信息的目标对水管理、工程和规划具有广泛的价值，CUAHSI HIS是帮助联邦水机构的数据交付服务发挥其全部潜力的一种手段。该项目还包括与纳瓦霍民族水资源计划的合作，以帮助整合和发布他们的水资源信息。在计算机行业，CUAHSI HIS作为构建分布式信息系统的典范而受到关注，该系统整合了帮助更好地管理我们国家的科学原则。
