Integrated, distributed hydrologic models leverage advances in computational power and data accessibility to improve predictive understanding of the water cycle. While impressive advances in this area of environmental modeling have been accomplished, such models are still rarely used, partially because of difficulty integrating model and data. This research describes the release of Watershed Workflow version 1.2, a new library aiming to automate and enable complex workflows defining inputs to high resolution, integrated, distributed hydrologic models. Watershed Workflow provides tools enabling the discovery, acquisition, mapping, and coordination of watershed geometry, land cover, soil properties, and meteorological data. It enables the construction of unstructured meshes that incorporate this data, and provides tools for automating a “first” simulation on any watershed in the United States. We present the design of the workflow tool, and describe best practices for its usage, culminating in a final example from watershed specification to simulation at the Coweeta Hydrologic Laboratory.

集成的分布式水文模型利用计算能力和数据可访问性方面的进步来提高对水循环的预测性理解。虽然在环境建模领域取得了令人瞩目的进步，但此类模型仍然很少使用，部分原因是模型和数据难以整合。这项研究描述了 Watershed Workflow 版本 1.2 的发布，这是一个新库，旨在自动化和启用复杂的工作流，定义高分辨率、集成、分布式水文模型的输入。Watershed Workflow 提供的工具能够发现、获取、映射和协调流域几何、土地覆盖、土壤特性和气象数据。它可以构建包含这些数据的非结构化网格，并提供用于在美国任何流域自动进行“首次”模拟的工具。我们介绍了工作流工具的设计，并描述了其使用的最佳实践，最终给出了从流域规范到 Coweeta 水文实验室模拟的最终示例。
