This model is an approximate implementation of the model described in
Stark CP 1994 Cluster growth modeling of plateau erosion. Journal of Geophysical Research, 99, 13957-13969.
which combines invasion percolation, diffusion-limited aggregation and Eden growth to simulated gullying erosion at a plateau edge.

This model shows how Eden spread along a front is dramatically altered by the occurrence of even relatively rare long-distance jumps. The behaviour of this model should be compared with that of the same model without such jumps.
An alternative version of the model is available, which makes use of the netlogo R extension.
