'pybedforms' is a Python version of 'Bedforms 4.0', a Matlab program written by David Rubin and Carissa Carter (see this USGS publication and this interactive webpage). The bedform topographies are created in exactly the same way as they were in Bedforms 4.0; however, the 3D visualization is different. We use Mayavi to build the block diagrams; these plotting functions were simplified from the 'blockdiagram' Python package. All the key classes and functions are in the 'dune_topo.py' module. The 'Notebook_with_examples' jupyter notebook illustrates how to build bedform models using (1) the default parameters and (2) a set of parameters predefined by Rubin & Carter. The model can be visualized as a block diagram using the "plot_3D" function:

You can also extract a "core" from the model and visualize it in 3D:

• matplotlib
• numpy
• mayavi
• skimage
• scipy
• tqdm
