FLUNETS is a tool to extract and order fluvial network from a Digital Elevation Model (DEM). The aim is to provide a continuous fluvial network, where the value of each river remains the same from the confluence upstream to the headwater. Refer to paper published for additional details

FLUNETS - Tool definition

FLUNETS is a tool to extract and order fluvial network from a Digital Elevation Model (DEM). The aim is to provide a continuous fluvial network, where the value of each river remains the same from the confluence upstream to the headwater. Refer to paper published in Geographia Technica for additional details: http://technicalgeography.org/pdf/2_2018/09_pastor.pdf. If you use these functions for a publication, please cite the linked paper.

Requirements

FLUNETS requires Matlab 2011b or higher version and the Image Processing Toolbox. FLUNETS internally uses TopoToolbox functions (DOI: 10.5194/esurf-2-1-2014) to calculate flow-related matrices derived from the DEM. It requires to download TopoToolbox:(https://github.com/wschwanghart/topotoolbox).

Getting started

The main script is FLUNETS_main.m. In FLUNETS_main.m, is where the stream_ordering_tools and TopoToolbox paths are set. Also is where the input data is specified.

The output files are an ordered drainage network given as a raster format and a CSV file with descriptive data of the network, such as the accumulation value of each river, the distance to the headwater, the length of the river, the drainage area, etc.
