Does model development still take place?	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	https://github.com/csdms-contrib/marssim
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.
