Scarp diffusion exercise from the International Quality Network Workshop
Simple Matlab diffusion modeling code and examples
by Ramon Arrowsmith
This is a simple matlab function that does diffusion modeling of profile development under transport limited and no tectonic displacement conditions. It provides plots of the profiel development at user-defined intervals and also shows the flux distribution at thos intervals. Remember that the erosion/deposition rate = the spatial derivative of the flux distribution.
A possibly useful reference is Appendix A from my dissertation.
Also note these web pages on Excel modling that are very similar:
Simulation of hillslope processes using Microsoft Excel
Matlab scripts and examples
Make sure that the function and the script to run it (given below--modify to see how things work) are in the same directory.
Here is the main diffuse function:
Example 1: scarp development
Example 2: Continuous motion along a vertical fault
Compare with above example
Example 3: Steadily uplifting hill
