This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).0846244GoodallThe principal objective of this proposal is to advance integrated modeling as an approach for building next generation watershed models to support environmental management. Integrated modeling is a systems-based approach for constructing models through the use of predefined modeling components. Each component represents some spatially-explicit system process, and the modeler defines how these components are coupled to simulate system response. Because components can be developed and maintained by different groups, yet can still be coupled within a modeling system, integrated modeling offers a transformative approach for constructing next generation, community-supported environmental models. This project will address a fundamental question in integrated modeling, that is the transfer of boundary conditions between spatially and temporally misaligned components, and produce results that will be used in future efforts in integrated modeling. This project will focus on the following research tasks to advance the science and adoption of integrated modeling: (1) to investigate scaling issues in integrated modeling, in particular algorithms for transferring values between coupled process-level components that operate on different spatial or temporal scales; (2) to prototype a set of process-level components for an integrated modeling system and apply these components to improve understanding of the performance and accuracy of integrated modeling approaches; and (3) to educate a new generation of environmental modelers in integrated modeling techniques to foster a community of integrated watershed modelers. If successful, this project will provide important guidance to integrated watershed modeling activities in the U.S. and abroad. The educational merit of this project will be to engage and mentor a new generation of watershed modelers in integrated modeling approaches. In addition to incorporating the basic skills and methods needed for integrated modeling into the engineering courses that I teach, the project will organize and host a summer workshop where an interdisciplinary group of graduate and undergraduate students will work together to prototype an integrated model for a local watershed. The educational and research activities will be integrated throughout the project duration by having the tools that result from the research plan used by students in the educational plan, and by using the feedback received from the students in the educational plan to enhance the user-friendliness of the tools developed in the research plan. The broader impacts of this research will be to the U.S. environmental policy arena through the interest of the Environmental Protection Agency (EPA) in integrated modeling approaches, to various scientific disciplines including the hydrologic and surface dynamics communities through their efforts to build cyberinfrastructure, and to the international water management community through collaborations with an international standards organization. Also, this research will involve underrepresented groups by both utilizing existing programs at the University of South Carolina that aim to involve minority students in graduate research and through my leadership in the formulation of a watershed management plan for a local watershed in South Carolina that is home to a significant percentage of minority residents.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。0846244goodall本提案的主要目标是推进集成建模作为建立下一代流域模型以支持环境管理的方法。集成建模是一种基于系统的方法，用于通过使用预定义的建模组件来构建模型。每个组件表示一些空间显式的系统过程，建模者定义如何将这些组件耦合以模拟系统响应。由于组件可以由不同的组开发和维护，但仍然可以在建模系统中耦合，因此集成建模为构建下一代社区支持的环境模型提供了一种转换方法。该项目将解决集成建模中的一个基本问题，即在空间和时间上不对齐的组件之间的边界条件的转移，并产生将在未来集成建模中使用的结果。本项目将重点开展以下研究工作，以推进集成建模的科学和应用：(1)研究集成建模中的尺度问题，特别是在不同空间或时间尺度上运行的耦合过程级组件之间传递值的算法；(2)为集成建模系统建立一组过程级组件的原型，并应用这些组件来提高对集成建模方法的性能和准确性的理解；(3)对新一代环境建模者进行综合建模技术教育，培养一个综合流域建模者社区。如果成功，该项目将为美国和国外的综合流域建模活动提供重要指导。这个项目的教育价值将是在集成建模方法中吸引和指导新一代分水岭建模者。除了将集成建模所需的基本技能和方法纳入我所教授的工程课程之外，该项目还将组织并主办一个夏季研讨会，由研究生和本科生组成的跨学科小组将共同为当地的分水岭制作集成模型的原型。教育和研究活动将在整个项目期间整合在一起，通过在教育计划中使用学生从研究计划中获得的工具，并通过在教育计划中使用学生的反馈来提高研究计划中开发的工具的用户友好性。这项研究将通过环境保护局（EPA）对综合建模方法的兴趣，对美国环境政策领域产生更广泛的影响，通过建立网络基础设施的努力，对各种科学学科，包括水文学和地表动力学社区产生更广泛的影响，并通过与国际标准组织的合作，对国际水管理社区产生更广泛的影响。此外，这项研究将涉及代表性不足的群体，通过利用南卡罗来纳大学现有的旨在让少数民族学生参与研究生研究的项目，以及通过我在南卡罗来纳当地流域制定流域管理计划的领导，该流域是少数民族居民的家园。
