Proof of Concept of a Hydrologic Multiphysics Model

水文模型在水文科学的进步和水文学对社会的预测贡献中起着关键作用。作为通过CUAHSI协调的一系列研讨会和会议的一部分，正在评估改进水文模型的各种选择，以调查开发水文科学建模平台的可行性。建模平台目前的愿景是，它将支持几个主要的软件包，每个软件包都有不同的功能。一个包将涵盖用于表示水文过程的正向模型，而其他包包括进行逆向建模、地质统计学、高级图形渲染以及与HIS等数据源的链接的功能。正演模拟软件包的一个选择是使用具有模拟各种过程能力的软件，然后根据水文学的具体应用定制软件。这一选择很有吸引力，因为它提供的模拟能力比现有水文模型提供的能力广泛得多。多物理场软件是最有前途的通用建模软件包，这种类型的软件已被用于水文学的各种应用。然而，应用范围有限，因此水文多物理场作为水文模拟平台的重要功能的可行性尚不清楚，本探索性建议的目的是获得许可证，并建立一个小型的模拟平台，旨在进行水文多物理场的概念验证评估。特别是，我们打算使用该软件来解决涵盖水文领域广泛主题的基准问题，以评估在水文建模平台上表示此类软件的价值。我们的目标是开发这些基准问题，使其结果可以用于评估水文多物理学的价值在计划明年的各种研讨会。该项目将由一组教师和研究生进行，他们具有广泛的经验，涵盖了水文学中的许多建模兴趣。我们需要尽快开始评估，以便在研讨会召开时取得成果，这就是我们提交一份探索性提案的原因。该提案旨在开始评估使用单一模型解决水文学中目前由许多模型解决的问题的可行性。这项活动的智力价值在于，它可以使水文学家将更多的智力资本投入到理解水文过程的科学中，而不是投入到选择、开发和维护相关模型的任务中。这种类型的贡献可以导致整个水文学领域的进步。该项目的广泛影响是，它将提供评估，指导如何制定水文建模平台的决策（它可能包括也可能不包括水文多物理场，这取决于该项目的成果）。水文多物理场的成功评估有可能展示将广泛的过程集成到水文模型（从生态到经济，或气候预测到农业和城市规划）的建模能力。这将对水文学和相关学科产生广泛影响。拟议的工作将涉及大约10名研究生和几名本科生，他们将学习一种新的建模方法，这将为将来向许多其他学生介绍这种方法铺平道路。

Hydrologic models play a key role in both the advancement of hydrologic science and the predictive contributions that hydrology makes to society. A variety of options for improving hydrologic models are being evaluated as part of a series of workshops and conference sessions coordinated through CUAHSI to investigate the feasibility of developing of a modeling platform for hydrologic sciences. The current vision for the modeling platform is that it will support several major software packages, each with distinct functionality. One package will cover forward models used to represent hydrologic processes, whereas other packages include capabilities to do inverse modeling, geostatistics, advanced graphical rendering, and linkages with data sources such as HIS. One option for a forward modeling package is to use software with capabilities to simulate a wide range of processes, and then tailor the software to specific applications in hydrology. This option is appealing because it offers simulation capabilities that are much broader than those provided by existing hydrologic models. Multiphysics software is the most promising of the general modeling packages, and this type of software has been used for a variety of applications in hydrology. However, the applications have been limited in scope, so the viability of hydrologic multiphysics as an important capability on a hydrologic modeling platform is unclear.The purpose of this exploratory proposal is to obtain licenses and set up a small modeling platform designed to for a proof-of-concept evaluation of hydrologic multiphysics. In particular, we intend to use the software to solve benchmark problems covering a wide range of topics in hydrology in order to evaluate the value of having this type of software represented on a hydrologic modeling platform. The objective is to develop these benchmark problems so the results can be used to evaluate the value of hydrologic multiphysics at the various workshops planned for the next year. The project will be conducted by a team of faculty and graduate students with a range of experience that covers much of the modeling interests in hydrology. We need to get started with the evaluation soon in order to have results when the workshops take place, and this is the reason we are submitting an exploratory proposal.This proposal seeks to begin to evaluate the feasibility of using a single model to solve problems that are currently addressed by many models within hydrology. The intellectual merit of this activity is that it may allow hydrologists to invest more of their intellectual capital in the science of understanding hydrologic processes and less in task of selecting, developing and maintaining relevant models. This type of contribution can lead to advances across the field of hydrology. The broad impact of this project is that it will provide evaluations that will guide decisions on how a hydrologic modeling platform is formulated (it may or may not include hydrologic multiphysics, depending on the outcome of this project). A successful evaluation of hydrologic multiphysics has the potential to demonstrate modeling capabilities that integrate a wide range of processes into hydrologic models (from ecology to economics, or climate forecasting to agricultural and urban planning). This will have broad impacts within both hydrology and associated disciplines. The proposed effort will involve approximately 10 graduate students and several undergraduates, who will learn a new modeling approach, and it will pave the way for introducing this approach to many additional students in the future.
