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:
  1. soil plate volume and tree diameter;
  2. soil plate width and tree diameter;
  3. soil plate depth and tree diameter.

These relationships have been calibrated based on field data in the Southern Blue Ridge (Appalachian Mountains).
