AR2-sinuosity

Generates planforms for single-thread channel using a second-order autoregressive model. This code creates the channel centerline (i.e., the line equidistant between two banks) for a single thread-channel, using a second-order autoregressive model. The code implements a model for random centerlines proposed by Ferguson, R. I. (1976) Disturbed periodic model for river meanders, Earth Surface Processes 1(4), 337-347, doi:10.1002/esp.3290010403. This implementation also includes (1) controls for the node spacing and extent of channels, (2) removal of self-intersecting (cutoff) loops from modeled centerlines, and (3) a wrapper script to sweep model parameter space and generate alternate realizations using different random disturbance series.
