Yes If above answer is no, provide end year model development Code development status When did you indicate the 'code development status'? Model availability Source code availability (Or provide future intension) 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 Comments -- This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component Not yet"Not yet" is not in the list (Yes, In progress, No but possible, No not possible) of allowed values for the "Code CMT compliant or not" property. PyMT component Is this a data component Can be coupled with:
