One-line model description	Matlab-based scripts to extract topometrics for catchments and identify river knickpoints.
Extended model description	--- WHEN USING THIS CODE FOR YOUR RESEARCH, PLEASE CITE: --- Neely, A., Bookhagen B., Burbank, D.W. (2017): An automated knickzone selection algorithm (KZ-Picker) to analyze transient landscapes: Calibration and validation, JGR Earth Surface, doi:10.1002/2017JF004250 available at: http://onlinelibrary.wiley.com/doi/10.1002/2017JF004250/full --- The Matlab-based scripts extract several topometrics at the catchment scale based on log area/log slope and chi plots. Topometrics include: steepness index, theta, steepness index with adjusted theta for each drainage basin, specific stream power, curvature, local relief, and others. Detrended and normalized chi-squared plots are used to identify river knickpoints. Output is written as GeoTIFF files, shapefiles, and CSV files. Additional information, examples, and tutorials are provided on the github page.
