Start year development	2008
Does model development still take place?	Yes

Source web address
Source csdms web address
Program license type	GPL v2
Program license type other
Memory requirements	--
Typical run time	Seconds to minutes

Describe input parameters	fraction of trees that move sediment when they die, # of plots to simulate, # of years to simulate, with or without growth of Chestnut.
Input format	ASCII
Other input format	Command line
Describe output parameters	Characteristics of tree growth (stand biomass, stem count, leaf area, diamter) and characteristics of sediment transport (sediment flux in m4/m/yr, # of tree falls)
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?	No
If above answer is yes
Other visualization software

Describe processes represented by the model	Growth, death, and regeneration of individual trees. Sediment flux moved by each tree.
Describe key physical parameters and equations	Species specific, logistic growth equation for individual trees. Sediment flux for each tree fall a function of sediment volume, transport distance, and hillslope angle. Sediment volume and transport distance a function of tree diamter.
Describe length scale and resolution constraints	Zero dimensional model simulating a 1/12 ha plot.
Describe time scale and resolution constraints	Annual time step, usually simulate ~1000 years.
Describe any numerical limitations and issues	--

Describe available calibration data sets	Requires calibration for relationship between: soil plate volume and tree diameter; soil plate width and tree diameter; soil plate depth and tree diameter. These relationships have been calibrated based on field data in the Southern Blue Ridge (Appalachian Mountains).
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?	no, but would like to

Is there a manual available?	No
Upload manual if available:
Model website if any	None
Model forum / discussion board
