Collaborative Research: SI2-SSI: An Interactive Software Infrastructure for Sustaining Collaborative Community Innovation in the Hydrologic Sciences

水的质量、数量、可获得性和管理对社会至关重要。然而，我们对控制水及其有效性的复杂相互交织的环境过程进行建模和定量理解的能力受到与水文数据发现、系统集成、建模/模拟和教育相关的工具不足的严重阻碍。该项目开发了可持续的网络基础设施，以便更好地获取水文科学中与水有关的数据和模型，使水文学家和其他相关社区能够协作并合并来自多个来源的数据和模型。它将提供创建和应用水文知识的新方法，以更好地了解水的可用性、质量和动态。它还将有助于更全面地了解水循环的自然和工程方面之间的相互作用。这些目标将通过开发可互操作的网络基础设施工具和创建在线协作环境来实现，该环境被称为“水共享”，使科学家能够轻松地发现和访问水文及相关数据和模型，将它们检索到他们的桌面上，并在高性能计算环境中进行分析。要开发的软件将利用现有的NSF网络基础设施(iRODS、HUBZERO、CSDMS、CUAHSI HIS)，并作为开放源代码创建。它的发展将是终端用户驱动的。在更广泛的影响方面，该项目通过开发软件工具和计算环境，为科学建立必要的基础设施，以便更好地了解气候变化(即洪水、干旱、生物燃料等)的影响。并允许改进地上和地下的水资源开发和淡水资源管理。由此产生的软件将向公众开放，并提供强大的学生和劳动力培训/教育组成部分。此外，该项目还支持处于EPSCoR状态的机构，并聘请科学和工程学代表不足的群体中的人作为私人投资者。

Water, its quality, quantity, accessibility, and management, is crucial to society. However, our ability to model and quantitatively understand the complex interwoven environmental processes that control water and its availability is severely hampered by inadequate tools related to hydrologic data discovery, systems integration, modeling/ simulation, and education. This project develops sustainable cyberinfrastructure for better access to water-related data and models in the hydrologic sciences, enabling hydrologists and other associated communities to collaborate and combine data and models from multiple sources. It will provide new ways in which hydrologic knowledge is created and applied to better understand water availability, quality, and dynamics. It will also help to provide a more comprehensive understanding of the interactions between natural and engineered aspects of the water cycle. These goals will be achieved through the development of interoperable cyberinfrastructure tools and the creation of an online collaborative environment, called HydroShare, which enables scientists to easily discover and access hydrologic and related data and models, retrieve them to their desktop, and perform analyses in a high performance computing environment. The software to be developed will take advantage of existing NSF cyberinfrastructure (iRODS, HUBzero, CSDMS, CUAHSI HIS) and be created as open source code. Its development will be end user-driven. In terms of broader impacts, the project builds essential infrastructure for science by developing software tools and computing environments to allow better understanding of the impacts of climate change (i.e., floods, droughts, biofuels, etc.) and to allow improved water resource development and the management of freshwater resources both above and below ground. Resulting software will be made publicly available and provides a strong student and workforce training/education component. In addition, the project supports an institution in an EPSCoR state and engages, as a PI, a person who is from a group under-represented in the sciences and engineering.
