Cellular automata are good candidates for modelling and simulating complex dynamical systems, whose evolution depends on the local interactions of their constituent parts. Many macroscopic phenomena have such features, but their complexity involves sometime the interaction of heterogeneous processes, whose composition is not immediate in a cellular automaton frame. Furthermore the managing of f...

Debris flows generated by rainfall runoff can occur in rocky alpine landscapes and burned steeplands. Runoff-generated debris-flow events are commonly composed of a series dense granular surge fronts separated water-rich flows. Owing to this intra-event variability flow composition mechanics, post-event interpretations preserved sedimentary deposits, or lack thereof, result dizzying mix that ra...

1. Maximum rate of cut that would provide a hillslope landslide rate of <20% over background, assuming no areas are protected by no-cut buffers .. Summary Downstream impacts to aquatic environments and property generally occur as cumulative watershed impacts, which are usually caused by changes in the transport of woody debris, water, and sediment through a watershed. The downstream cumulative ...

Debris flows are typically a saturated mixture of poorly sorted particles and interstitial fluid, whose density and flow properties depend strongly on the presence of suspended fine sediment. Recent research suggests that grain size distribution (GSD) influences excess pore pressures (i.e., pressure in excess of predicted hydrostatic pressure), which in turn plays a governing role in debris flo...
