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.

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
