Catchmentwide erosion rate calculator

Catchmentwide Erosion Rate Calculator for in situ cosmogenic nuclides

This calculator processes geospatial data (digital elevation model, catchment outline and other) to extract hypsometry statistics of the catchment and determine a cosmogenic nuclide catchmentwide erosion rate. It uses the online erosion rate calculator by Greg Balco (e.g. http://stoneage.hzdr.de/) to calculate cosmogenic nuclide production.

The method currently works for in situ Be-10 and Al-26 data and is considered robust for catchments up to approx. 600 km x 600 km; for larger catchments the effect of latitude on cosmogenic production may become significant.

Installation and Usage

This software has been developed on python 3.9 and needs the packages xarray, rasterio, fiona and pyproj as well as several other common python packages. Example scripts are provided as jupyter notebooks.

This release has two folders: The folder riversand has the actual code. The folder example_scripts is an example of what your project might look like. It has two jupyter notebooks quickstart.ipynb and step-by-step.ipynb and a folder test_data with example data.
