This plugin has an experimental version available!
It automates the extraction of main valleys and ridges, creates off-contour line and supports creating Keyline Designs and other water-retention planning measures. The tool can also be used for other tasks, such as planning the location and alignment of paths and roads.
DISCLAIMER: Influencing surface runoff on land is complex and requires significant expertise. This tool is intended as an aid for users with experience in land surface water management.
Core algorithms leverage WhiteboxTools (Lindsay, 2017–2020; see https://github.com/jblindsay/whitebox-tools).
So make shure you have installed and configured the plugin "WhiteboxTools for QGIS"!

This plugin requires several Python packages (numpy, shapely, pandas, geopandas, scipy).
These packages are typically included in common newer QGIS distributions, but may be missing in some installations (especially custom builds). If a package is missing, follow the installation instructions below:
- Windows, QGIS installed with OSGeo4W: https://landscapearchaeology.org/2018/installing-python-packages-in-qgis-3-for-windows/
- macOS (terminal): https://gis.stackexchange.com/questions/351280/installing-python-modules-for-qgis-3-on-mac
Take care to install compatible package versions.
A series of manual videos will follow soon: How to install a plugin with dependencies; how to use the tool, i.e. how to create a keyline design.
