A CUAHSI Scoping Workshop on a Community Hydrologic Modeling Platform in Washington, DC

本提案请求资金支持“范围界定”。工作坊探讨社区水文模拟活动在水文学方面的需要和要求。这项活动暂定名为社区水文建模平台（CHyMP），并被提议作为大学联盟促进水文科学公司（CUAHSI）下一个5年阶段的两项新主要举措之一。CHyMP的目标是通过社区建模活动，包括通用模拟软件的开发、分发和技术支持，显著提高水文模拟能力。CHyMP的当前愿景是一个平台，该平台将支持多个建模包，用于正演建模、逆建模、随机建模、图形可视化、访问数据源和其他功能。这一愿景将通过最初的范围界定研讨会（此处建议）和两个后续研讨会进行修改和完善。CHyMP的一个重要成果将是一个可以跨尺度应用的综合水循环建模框架，并用于解决没有它就无法解决的复杂水文研究问题。第一次讲习班的目标是调查关于社区水文模拟活动应采取的范围和形式的各种观点。研究结果将是成立一个生态环境模型工作小组，并向社会各界提交一份报告，说明进行水文生态模型的基本原理和初步策略。在确定范围和后续研讨会之后，我们期望pi领导的研究团队将向NSF提出开发和实施该平台的正式建议。所提议的研讨会的智力优点是表达了社区水文建模平台的形式和要求。研讨会的更广泛的影响是可能为水文学和相关社区提供综合水循环建模工具，以及这些工具将使新的研究成为可能。

This proposal requests funds in support of a ?scoping? workshop to explore the needs and requirements for a community hydrologic modeling activity in hydrology. This activity is tentatively called the Community Hydrologic Modeling Platform (CHyMP) and it is proposed as one of two new major initiatives for the next 5-year phase of the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI). The goal of CHyMP is to significantly advance hydrologic simulation capabilities via a community modeling activity, including the development, distribution and technical support of common simulation software. The current vision for CHyMP is of a platform that would support several modeling packages for forward modeling, inverse modeling, stochastic modeling, graphical visualization, access to data sources, and other features. This vision will be modified and refined through an initial scoping workshop (proposed here) and two follow-on workshops. An important outcome of CHyMP would be a framework for integrated water cycle modeling that could be applied across scales and for solving complex hydrologic research questions that could not be addressed in its absence. The goal of the first workshop is to survey the range of perspectives on the scope and form that a community hydrologic modeling activity should take. The outcome will be the establishment of a CHyMP working group and a report to the community on the rationale and preliminary strategy for undertaking community modeling in hydrology. Following the scoping and follow-on workshops, we expect that a PI-led research team will make a formal proposal to the NSF for the development and implementation of the platform. The intellectual merit of the proposed workshop is the articulation of the form and requirements for a community hydrologic modeling platform. The broader impacts of the workshop are the potential provision of integrated water cycle modeling tools to the hydrologic and related communities, as well as the new research that these tools will enable.
