Abstract

The original Hardenberg's model of biomass patterns in arid and semi-arid regions is revisited to extend it to more general non flat regions. It is proposed a technique to study these more generalized (non-flat) regions using both a conservation criterion and a explicit spatial dependent function ν(x)\nu (x). In this paper a study of dynamical stability around system's fixed points made. Under the idea of predictability via air images a fitted relationship among dynamical variables at stable fixed points is stablished. Also, is presented a discrete version of the model, in the form of Cellular Automata techniques, that allows to neglect the spatial scale and reproduces realistic stable spatial patterns.
