SHUD Modeling System

SHUD (Simulator for Hydrologic Unstructured Domains,水文非结构域模拟器)模型,是一个多时间尺度、多空间尺度、物理性的分布式水文模型,使用有限体积方法(Finite Volume Method)求解水文微分方程的数学模型。模型实现了地表水地下水全耦合,可实现流域水资源在积雪、土壤水、地下水、径流等组分的高时空分辨率模拟。 SHUD在模拟洪水淹没、水文跟踪、地上地下水交互、水资源评价等方面拥有显著优势;模型已在中国、美国及非洲各地有诸多研究案例。

From concept to practice to policy: modeling coupled natural and human systems in lake catchments
Recent debate over the scope of the U.S. Clean Water Act underscores the need to develop a robust body of scientific work that defines the connectivity between freshwater systems and people. Coupled natural and human systems (CNHS) modeling is one tool that can be used to study the complex, reciprocal linkages between human actions and ecosystem processes. Well-developed CNHS models exist at a conceptual level, but the mapping of these system representations in practice is limited in capturing these feedbacks. This article presents a paired conceptual-empirical methodology for functionally capturing feedbacks between human and natural systems in freshwater lake catchments, from human actions to the ecosystem and from the ecosystem back to human actions. We address extant challenges in CNHS modeling, which arise from differences in disciplinary approach, model structure, and spatiotemporal resolution, to connect a suite of models. In doing so, we create an integrated, multi-disciplinary tool that captures diverse processes that operate at multiple scales, including land-management decision-making, hydrologic-solute transport, aquatic nutrient cycling, and civic engagement. In this article, we build on this novel framework to advance cross-disciplinary dialogue to move CNHS lake-catchment modeling in a systematic direction and, ultimately, provide a foundation for smart decision-making and policy.
