Implementing the SCIDDICA landslide model in Cell-DEVS

ABSTRACT

The SCIDDICA model is a custom cellular automata used to simulate and analyse landslides and debris flows. It models landslides by tracking the amounts of kinetic energy and debris in the slide and using a set of simple rules to determine the movement of the kinetic energy and debris from cell to cell.

CD++ is a toolkit for implementing DEVS and Cell-DEVS models. We present an attempt to implement SCIDDICA using DEVS and CD++. A DEVS based definition of the SCID-DICA model introduces the advantages of the DEVS formalism to the model, and would allow formal verification of the DEVS definition of the model. This also permits us to integrate a SCIDDICA based landslide with other DEVS models, allowing larger and more complex simulations to be developed.
