The input file is a text file and users are required to input:
Time (in model years)
dT (the time step in fractions of a year)
tauc (Critical Shear stress for portions of the channel that are vegetated in Pascals)
taucWepp (Critical Shear stress for portions of the channel that are soil in Pascals)
lenzone (the length of channel that is bare soil in Meters)
Pmmphr (Rainfall to be used for erosion in Millimeters per Hour)
tval (this is the number of loop iterations before a profile is saved as output)
Immphr (Infiltration to be used for erosion in Millimeters per Hour)
One additional input:
One must supply the input length of the channel as a matlab data array called xcell.mat
manning's n for vegetation
manning's n for soil
critical shear stress for vegetation
critical shear stress for soil
rainfall
infiltration
This works for channels of hundreds of meters with 1 m cells
Numerical instabilities occur if the time step is too large.
The output are elevation values that represent the gully channel profile.
This code will erode cells according to a shear stress and also deposit sediment based on the concentration of sediment in a modeled water column. Additionally it has a headcut that migrates upstream and as the headcut erodes it deposits sediment downstream that the model must erode.
It is typically run for times no less than 25 years and no greater than 700 years.
As is, no updates are provided

This model is designed to simulate longitudinal profiles with headward advancing headcuts. This model simulates gully erosion on the centennial-scale given information such as average rainfall and infiltration rates. The modeler also specifies a headcut erosion rate and or a rule for headcut retreat (either discharge-dependent or height-dependent retreat).
