在大多数环境和自然资源评估、分析和研究中,分水岭和水文地貌划定是关键的第一步。虽然现有的地理空间工具提供了特殊的进步,很少有人关注开发全自动化的工具,将景观细分为组成水文地貌单元或离散河流走廊功能。在这里,我们提出了一个新的,开源的ArcGIS工具箱,称为犹他州州立大学AppLied(USUAL)流域工具。USUAL工具是一组简化的、易于使用的ArcGIS工具箱,可自动划分流域、子集水区、河流相邻河间和离散化河流网络,并具有通过大型流域进行一维源汇输运建模所需的拓扑结构和要素属性。这个新颖的地理空间工具集取代了对大量划定工作流程的需求,为地球科学、环境科学和自然资源社区提供了以ArcGIS用户熟悉的格式快速、轻松地自动化必要但通常耗时的任务的能力。
Watershed and hydro-geomorphic delineation is a critical first step in most environmental and natural resource assessments, analyses, and research. While existing geospatial tools have provided exceptional advances, less attention has been put toward developing fully automated tools for subdividing landscapes into their constituent hydro-geomorphic units or discretizing river corridor features. Here, we present a new, open-source ArcGIS toolbox, called the Utah State University AppLied (USUAL) Watershed Tools. The USUAL Tools are a set of streamlined, easy-to-use ArcGIS toolboxes that automate the delineation of watersheds, sub-catchments, river-adjacent interfluves, and discretized river networks with the topological structure and feature attributes necessary for one-dimensional source-to-sink transport modeling through large watersheds. This novel geospatial toolset replaces the need for extensive delineation workflows, providing the Earth science, environmental science, and natural resources communities with the ability to rapidly and easily automate necessary but often time-intensive tasks in a format familiar to ArcGIS users.
