Introduction
This code has been developed by the University of Edinburgh Land Surface Dynamics group to analyse channel longitudinal profiles using the integral method of channel analysis. The integral method is a means of comparing the relative steepness of channel profiles, normalized for drainage area. It is similar to, but has some advantages over, traditional slope area analysis. See Perron and Royden (2013) for more details on the integral method.
This particular code not only transforms channels using the integral method, but it also uses statistical techniques to find the most likely series of channel segments with distinct steepness and the most likely m/n ratio. The details of these algorithms can be found in Mudd et al. (submitted manuscript) which is available here: http://www.geos.ed.ac.uk/homes/smudd/Muddetal_JGRsubmit.pdf.
The code consists of objects that contain topographic data and their member functions, and driver programs perform the analyses. Full documentation is available under the ‘other’ tab in the wiki.

History
This code has been under development since 2012; Simon Mudd began the project and David Milodowski, Stuart Grieve and Declan Valters have all contributed to its development. Fiona Clubb, Declan Valters and Jen Merritt at the University of Edinburgh began beta testing in January 2013. Rahul Devrani and Vimal Singh of the University of Dehli began beta testing in April of 2013, and TC Hales of Cardiff University began beta testing in May 2013. The working version of the code used in the manuscript was finished in June 2013.
