Description: A cellular automaton model for simulating the development of aeolian dune landscapes under the influence of vegetation and biota (parabolic dunes, blowouts, foredunes, nebkha dunes). Technical information Supported platforms: Windows Programming language: C++, Matlab Model was developed started from: 2005 To what degree will the model become available: As teaching tool and as an executable. Basic algorithm is very simple and transferrable Current license type: -- Memory requirements: Variable Typical run time: Variable Input / Output description Input parameters: Staring grid topography and vegetation maps, control parameters such as potential transport rates, vegetation response functions Input format: ASCII Output parameters: resultant landscape topography and vegetation distributions; annual avalanching statistics Output format: ASCII Post-processing software (if needed): yes, Any package for imaging DEMs and vegetation maps Visualization software (if needed): yes: ESRI, IDL, Matlab Process description Processes represented by model: development of dune landscapes under the interaction between aeolian sand transport and vegetation growth and response Key physical parameters & equations: potential sand transport rate, sediment avaliability, vegetation response characteristics Length scale & resolution constraints: smallest cell should be equivalent to basic plant element (bush, grass clump) Time scale & resolution constraints: lower limit akin to days, no upper limit Numerical limitations and issues : heavy sequential number crunching (not written for parellel processing) Testing Available calibration data sets: none yet; in development Available test data sets: none yet; in development Ideal data for testing: field monitoring of geomorphic development and vegetation mapping, long-term required User groups Currently or plans for collaborating with: yes, future plans for collaborating on applying and comparing the model with real-world landscapes Documentation Key papers of the model: Baas (2002) Geomorphology,48.
