Discrete ECogeomorphic Aeolian Landscape (DECAL) modelling

Joanna Nield

Simulated vegetated aeolian dune landscapes under different environmental conditions. Dune types range from stabilised parabolic dune landscapes (d) to transgressive transverse (c) under drought conditions. (Nield and Baas, 2008, GPC)

Research in collaboration with Andreas Baas, King's College London.

DECAL is a cellular automaton based model which incorporated mutual feedback processes between geomorphic forcing and ecological growth to investigate fundamental controls, self-organising and non-linear behaviour in semi-arid aeolian dune environments. This project explores landscape evolution and disturbance response, developing a phase-space in which dune fields can be quantified.
