Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Landscape-Scale Model domain Terrestrial One-line model description GUI implementation of the Werner (1995) cellular automata aeolian dune model Extended model description This model is a GUI implementation of a simple cellular automata dune model. The model was originally proposed by Werner (1995, Geology 23) and has seen several extensions. It can simulate basic barchan, transverse, star, and linear dunes. The model is designed to be easy to operate for researchers or students without programming skills. Also included is a tool to operate the model from ArcGIS.

No If above answer is no, provide end year model development Code development status As is, no updates are provided When did you indicate the 'code development status'? 2020 Model availability As code, As teaching tool Source code availability (Or provide future intension) Through web repository Source web address https://github.com/tbarchyn/WDUNE Source csdms web address Program license type GPL v2 Program license type other Memory requirements Typical run time dependant on model space size Describe input parameters Arc ASCII grids of topography and non-erodible basement. Program will create input grids also. Input format ASCII Other input format Describe output parameters Arc ASCII grids of topography and non-erodible basement. Output format ASCII Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? Yes If above answer is yes ESRI, IDL, Matlab Other visualization software Any simple GIS viewer that can read ASCII grids. Describe processes represented by the model Aeolian transport and dune formation. Describe key physical parameters and equations The model is abstract. Refer to accompanying paper and references therein: Barchyn TE, Hugenholtz CH. 2011. A new tool for modeling dune field evolution based on an accessible, GUI version of the Werner dune model. Geomorphology. Available from: http://dx.doi.org/10.1016/j.geomorph.2011.09.021 Or, also, refer to original description of the model: Werner, BT. 1995. Eolian dunes: computer simulations and attractor interpretation. Geology 23, 1107-1110. Available from: http://dx.doi.org/10.1130/0091-7613(1995)023<1107:EDCSAA>2.3.CO;2 Describe length scale and resolution constraints The model is abstract. Ratio of height to horizontal distance resolution is locked at 0.1, but can be modified in the source code and re-compiling. Describe time scale and resolution constraints The model is abstract. Time given in iterations, relating iterations to real time depends strongly on the climate of the area simulated. Describe any numerical limitations and issues The model is abstract. Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets Upload test data sets if available: Describe ideal data for testing Do you have current or future plans for collaborating with other researchers? I'd be happy to help facilitate dissemination of extensions or improvements to this model. Is there a manual available? Yes Upload manual if available: Model website if any All source code, the model, and manual is available from download site, here: http://people.uleth.ca/~chris.hugenholtz/web/wdune.html Model forum / discussion board Comments This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant Yes WMT component No but possible PyMT component Is this a data component Can be coupled with:
