One-line model description	Matlab-based script to extract topometrics for catchments and river knickpoints.
Extended model description	--- WHEN USING THIS CODE FOR YOUR RESEARCH, PLEASE CITE: --- Neely, A., Bookhagen, B., Burbank, D.W. (in review): Connecting Stream Transience and Hillslope Evolution: Insights from a Knickpoints Selection Algorithm applied to Santa Cruz Island, California, JGR-Earth Surface --- The Matlab-based script extract several topometrics at the catchment scale (drainage area and stream-order size can be adjusted) based on log area/log slope and chi-squared plots. Topometrics include: steepness index, theta, steepness index with adjusted theta for each drainage basin, specific stream power, curvature, local relief, and others. Output is written as GeoTIFF files, shapefiles, and CSV files. In a second step, detrended and normalized chi-squared plots are used to identify river knickpoints. Output is written as shapefile and CSV files.
