河流系统由在多个时空尺度上出现的水文地貌斑块（HP）组成。功能过程区（FPZ）是存在于河谷尺度的 HP，是构建整个流域研究问题和管理计划的重要地层。分层分类程序根据河流的水文地貌特征对河段进行分组，有助于 HP 识别；然而，利用实地方法收集此类程序所需的数据通常是不切实际的。我们开发了一套基于 GIS 的工具，可促进快速、低成本的河流景观特征描述和 FPZ 分类。我们的工具称为 REsonate，由专为 ESRI ArcGIS® 设计的自定义工具箱组成。 REsonate 从现成的地理空间数据集和从建模程序导出的数据集中自动提取 13 个水文地貌变量。专为 MATLAB® 设计的先进 2D 洪水模型 FLDPLN 用于通过系统地淹没河网来确定山谷形态。当与其他建模程序结合使用时，RESonate 和 FLDPLN 可以以非常低的成本快速评估大型河流网络的特征。在这里，我们描述工具和模型的功能以及它们的优点、局限性和应用程序。
River systems consist of hydrogeomorphic patches (HPs) that emerge at multiple spatiotemporal scales. Functional process zones (FPZs) are HPs that exist at the river valley scale and are important strata for framing whole-watershed research questions and management plans. Hierarchical classification procedures aid in HP identification by grouping sections of river based on their hydrogeomorphic character; however, collecting data required for such procedures with field-based methods is often impractical. We developed a set of GIS-based tools that facilitate rapid, low cost riverine landscape characterization and FPZ classification. Our tools, termed RESonate, consist of a custom toolbox designed for ESRI ArcGIS®. RESonate automatically extracts 13 hydrogeomorphic variables from readily available geospatial datasets and datasets derived from modeling procedures. An advanced 2D flood model, FLDPLN, designed for MATLAB® is used to determine valley morphology by systematically flooding river networks. When used in conjunction with other modeling procedures, RESonate and FLDPLN can assess the character of large river networks quickly and at very low costs. Here we describe tool and model functions in addition to their benefits, limitations, and applications.
