B
A compilation of examples and documentation can be found in this Badlands-doc GitHub repository (http://github.com/badlands-model/Badlands-doc). +
C
A documented numerical stability criterium must be adhered to for the solution to remain stable. +
G
Analytical solution produces unrealistic results with low elastic thickness and/or very large cells due to the Green's function approximation. +
A
Artificially limit the alpha values between 2 and -2 and the constant values between 0 and 2.
Done so to avoid extreme outliers. +
H
As the size of the DEM increases, processing time will increase. An 8000*8000 DEM will take several days to process. Documentation is available to help users select appropriate input parameters. +

C
F
At the present I am trying to improve the wetting and drying algorithm, unphysical large velocities are sometime produced at the wet/dry front. +
B
S
Becomes very slow if run on domains with pits. Options include filling pits before running the model, or using the Landlab DepressionFinderAndRouter. +
G
Catchment must be small enough that it can be approximated as being flat. +
A
Code is research grade +
