Abstract

Lakes have significant impacts on watershed hydrology. However, until now, no web-based tool has been available for watershed delineation considering lakes. In this study, we developed a tool to address this, enabling non-exports to delineate watersheds. First, a conceptual data model was proposed to represent related spatial units and their flow relationships, including rivers, lakes, river sub-basins, lake hillslopes, and flow paths. Subsequently, a web-based tool was designed and implemented, which enables users to select an area of interest and obtain watershed delineation results without the need for software installation or data preparation. This tool also supports for the customization of data and parameters. Two case studies, conducted at the Fushi Reservoir and Mahu Lake, demonstrated the system's usability. To our knowledge, this study presents the first web-based tool for watershed delineation that considers lakes, and it has great potential for applications in watershed modeling and management.

基于网络的湖泊和水库流域划分工具

湖泊对流域水文有重大影响。然而，到目前为止，还没有基于网络的工具可用于考虑湖泊因素的流域划分。在本研究中，我们开发了一种工具来解决这一问题，使非出口商能够划定流域。首先，我们提出了一个概念数据模型，用于表示相关的空间单元及其流动关系，包括河流、湖泊、河流子流域、湖泊山坡和流动路径。随后，设计并实施了一个基于网络的工具，用户可以选择感兴趣的区域，无需安装软件或准备数据即可获得流域划分结果。该工具还支持数据和参数的定制。在 Fushi 水库和 Mahu 湖进行的两个案例研究证明了该系统的可用性。据我们所知，这项研究提出了第一个考虑湖泊的基于网络的流域划分工具，它在流域建模和管理方面具有巨大的应用潜力。

期刊介绍： Environmental Modelling & Software publishes contributions, in the form of research articles, reviews and short communications, on recent advances in environmental modelling and/or software. The aim is to improve our capacity to represent, understand, predict or manage the behaviour of environmental systems at all practical scales, and to communicate those improvements to a wide scientific and professional audience.
