Yes If above answer is no, provide end year model development Code development status When did you indicate the 'code development status'? Model availability As code Source code availability (Or provide future intension) Through CSDMS repository Source web address Source csdms web address Program license type Other Program license type other None Memory requirements Variable - dynamic arrays Typical run time hour to days Describe input parameters Initial elevation file. File specifying boundary conditions, run time, process options, and parameter values. Input format ASCII Other input format Describe output parameters RAW image files of elevation and shaded relief. ASCII file of elevations at specified times. ASCII files of other state variables as desired at specified times. Iteration-by-iteration summary file Output format ASCII Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? Yes Describe post-processing software Photoshop to produce movies. Conversions to a variety of data formats. Visualization software needed? Yes If above answer is yes Other visualization software Surfer for topographic maps Describe processes represented by the model Bedrock fluvial incision (shear stress or sediment flux dependency). Mass wasting (creep and threshold-limited). Bedload sediment transport & deposition in streams, fans, deltas. Impact cratering, aeolian deposition, lava flows. Flow routing with evaporation from depressions. Describe key physical parameters and equations Bedrock erodibility, mass wasting diffusivity, bed material grain size, flow hydrologic parameters, relative evaporation rate, cratering size distribution and rate, eolian deposition parameters, etc. Describe length scale and resolution constraints Variable - targeted towards drainage basin or larger scales. Spatial scale determined by input parameter and run-time specification of array dimentions. Uses rectangular grid cells. Describe time scale and resolution constraints Variable - Limited by computer speed. Describe any numerical limitations and issues Runs with grid sizes greater than about 600x600 may require many days on a PC. Model assumes fluvial streams have gradients determined by steady-state transport. Depositional stratigraphy not modeled. Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets Example runs for most types of simulation scenarios Upload test data sets if available: Describe ideal data for testing Do you have current or future plans for collaborating with other researchers? Yes, at present primarily in the planetary community. Is there a manual available? Yes Upload manual if available: Media:marssim_program.pdf Model website if any http://erode.evsc.virginia.edu Model forum / discussion board Comments Most recent model available from ah6p@virginia.edu. This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component Yes PyMT component Is this a data component Can be coupled with:
