Code and data for "Computational morphology of debris and alluvial fans on irregular terrain using the visibility polygon"

This code is for simulating conical fan morphologies. 

The code and the dataset can be read/run by using Matlab. The description is as follows:

1. Dataset (FieldCase1Input.mat, FieldCase2Input.mat) provides the input data needed to simulate the two field cases. The simulations can be run using the code Case4_FieldCase1.m and Case5_FieldCase2.m. The results can be compared with the provided output data (FieldCase1Output.mat, FieldCase2Output.mat).

2. Code for three idealized cases, including the comparison of analytical solutions and model simulations are provided.

3. Function VisiPolygon is the algorithm for calculating point visibility polygon. Function FanTopo_slope is the model for simulating fan morphology.
