RivGraph

RivGraph is an open-source software tool hosted on GitHub, developed by VeinsOfTheEarth. Its primary function is to automate the extraction and quantification of river and delta channel networks from binary masks. This process transforms raw imagery data into structured graphical representations, making complex river systems amenable to quantitative analysis and detailed study. The project aims to provide a robust and accessible solution for researchers in various earth science disciplines.

The tool offers significant capabilities for hydrological and geomorphological research, enabling scientists and researchers to study river network dynamics, delta evolution, and water flow patterns more efficiently. By generating graphical models, RivGraph facilitates the precise measurement of various network properties, such as length, connectivity, bifurcation ratios, and drainage density. These metrics are crucial for understanding fluvial processes, assessing river health, and modeling environmental changes over time.

As a Python-based solution, RivGraph seamlessly integrates into existing data analysis workflows for remote sensing and GIS applications. It is particularly valuable for projects involving large datasets of satellite or aerial imagery where manual network extraction would be prohibitively time-consuming and prone to human error. The software aims to streamline the analysis of river systems for environmental monitoring, conservation efforts, and the assessment of climate change impacts on aquatic ecosystems, providing a standardized approach to network characterization.
