Describe input parameters Domain dimensions and cell size (regular 2D grid). Initial condition.

Locations and rates of sediment and water influxes. Subsidence pattern and rate. Sea level curve. (Presently all boundary conditions are constant, but could vary in space and time in future versions)

Input format ASCII
Other input format Runs from Matlab command line
Describe output parameters Time series of 2D topography/bathymetry and water discharge. 3D stratigraphy grid

(currently model is single grain-size, so stratigraphy only stores deposit age)

Output format ASCII
Other output format 2D grids can be ASCII, but stratigraphy is custom-designed structure stored in Matlab format.

Describe processes represented by the model The key processes are 1) topographically-driven overland flow and 2) bedload transport by this flow. Through these processes the model self-organizes channels which incise, back-fill, and avulse. Processes are similar to alluvial fans. There are no marine processes besides bedload dumping.
Describe key physical parameters and equations Topographic slope-weighted multiple flow direction water routing. Stream power transport.
Describe length scale and resolution constraints There are two primary constraints:
  1. Like most topographically-routed cellular river models, incised channels in the model will always be one cell wide. Hence it should not be applied at scales where the cell size is much less than main channel widths.
  2. The model does not really simulate low-Froude low-slope rivers such as most large coastal deltas. However processes are similar to many other codes (e.g. DIONISOS) commonly used for large-scale deltas. If primary questions are about large-scale basin filling on O(10 ka) or longer timescales the model should be fine. However when questions relate to details of sub-millenial geomorphic processes or reservoir-scale stratigraphic architecture, some care must be taken in interpreting model results.
Describe time scale and resolution constraints See above.
Describe any numerical limitations and issues Numerical limitations and issues:
  1. Currently the model runs with a constant timestep, which is limited by the maximum inflow. Future versions may include adaptive time-stepping.
  2. As mentioned above, the model channels tend to be one or two cells wide. Future versions may address this issue with some combination of diffusive regularization or multi-scale modeling.
