This dataset contains three files which accompany the simulations (in MATLAB) associated with the publication of my dissertation. The first is a small input file which sets the initial planform of the channel of a meandering river. The second and third files are the resulting evolution through time, saved at 30 year time intervals but offset so that the actual temporal sequence is the first element from one file, then the first element from the other file then the second element from each file. These output files can serve as a check for other simulations, or save the simulation time required to generate them. See the accompanying dissertation document (to be referenced once the official reference is available) and the GitHub repository which includes the code required. The core 'engine' of this simulation was originally published as dowloadable code files in the supplementary online materials associated with this paper: Schwenk, J., Lanzoni, S., & Foufoula‐Georgiou, E. (2015). The life of a meander bend: Connecting shape and dynamics via analysis of a numerical model.
