System for Producing RIver Network Geometry (SPRING) - A conceptual model for generating river bathymetry for entire network in a watershed

Modeling riverine processes require accurate representation of topography. However, Digital Elevation Models (DEMs) do not have complete bathymetric representation and need to be augmented with additional bathymetry data. SPRING is a conceptual bathymetry generation tool for creating 3D representation of river channel geometry that can be incorporating into traditional DEMs to develop a complete a more accurate "topo-bathy" DEM. SPRING has an automated framework for processing entire river network in a watershed with minimal user intervention, thereby, enabling it to process large watersheds efficiently. This is a significant advantage over other currently available river bathymetry generation tools which can only process single reaches. Additionally, most of the conceptual bathymetric models currently available to fluvial modelers create symmetric functional surfaces, which do not reflect the anisotropic characteristics of the river channel. SPRING captures the anisotropy in river geometry due to a meandering thalweg, thereby, creating asymmetric river channels that are more representative of natural river systems.

This resource contains an initial release of SPRING. It is available to users as a toolbar in ArcMap, which deploys intuitive Graphic User Interfaces (GUIs) to ensure that no programming (coding) background is required for implementing SPRING. Following files are included with this resource:
1) Installation File: This folder contains a zipped file of the SPRING windows installer (.msi)
2) SPRING_short_instructions.pdf: As the name suggests, these are concise instructions to set up and get SPRING running for the sample data
3) SPRING_User_Manual.pdf: These are slightly more detailed instructions about getting SPRING to run on the user’s dataset. It has more background and troubleshooting information on SPRING.
4) Sample Data: This folder contains a set of sample data. It has a DEM (“sampledem”) and a file geodatabase (“Sample_Data.gdb”). The file geodatabase contains all the input, intermediate and output feature classes that are needed by SPRING.

模拟河流过程需要对地形进行精确的描绘。然而，数字高程模型（DEM）并未完全包含水深信息，因此需要通过额外的水深数据来补充。SPRING 是一款概念性的水深生成工具，旨在创建河流水道几何形状的 3D 表示，并能够将其融入传统的 DEM 中，以开发一个更为完整且精确的“地形-水深”DEM。SPRING 拥有自动化的框架，能够以最小的用户干预处理整个流域内的河流网络，从而使其能够高效地处理大型流域。这一点相较于其他目前可用的河流水深生成工具具有显著优势，因为后者只能处理单个河段。此外，目前大多数提供给河流模型师的概念性水深模型都创建对称的功能表面，而这些表面无法反映河流水道的各向异性特征。SPRING 通过捕捉因弯曲主航道而产生的河流几何各向异性，从而创建出不对称的河流水道，这些水道更符合自然河流系统的特征。

本资源包含了 SPRING 的初始版本。它以工具栏的形式存在于 ArcMap 中，并部署了直观的图形用户界面（GUI），以确保无需编程（编码）背景即可实施 SPRING。以下文件包含在此资源中：

1) 安装文件：此文件夹包含 SPRING Windows 安装程序（.msi）的压缩文件。

2) SPRING_short_instructions.pdf：如名称所示，这是一份简明扼要的设置和运行 SPRING 以处理示例数据的说明。

3) SPRING_User_Manual.pdf：这是一份更详细的说明，关于如何在用户的数据集中运行 SPRING。它包含了更多关于 SPRING 的背景信息和故障排除信息。

4) 样本数据：此文件夹包含一系列样本数据。它包含一个 DEM（“sampledem”）和一个文件地理数据库（“Sample_Data.gdb”）。文件地理数据库包含了 SPRING 所需的所有输入、中间和输出要素类。
