Many of the algorithms used in RichDEM are documented in journal or conference publications. In the case of older algorithms by other authors, it is often possible to find the paper in the literature. Some of the newer algorithms I developed have not yet had a chance to be widely utilized. These algorithms are listed below.
Additionally, each publication has its own GitHub repository featuring easily-compiled, minimum working examples of the algorithms, along with examples and test data sets.
These are available as follows:
The algorithms used in RichDEM have been published in the following articles. Every algorithm/program will provide its relevant citation information when run.
