Welcome to the Landlab Notebooks

This page is provides an index to the Landlab Jupyter Notebooks.

If you are not certain where to start, consider either:

• the Landlab Syllabus if you are interested in teaching yourself Landlab
• the Landlab teaching notebooks if you are an educator looking for tutorials to use in the classroom.

• The Landlab Documentation
• The Landlab code base

Notebooks by topic

Introduction to python

• Introduction to Python and NumPy Learn about: The very basics of Python.

Introduction to Landlab

• Introduction to Landlab: example model of fault-scarp degradation A short overview of some of the things Landlab can do.
• Where to get info about Landlab
• Introduction to Landlab: diffusion three ways
• Introduction to the model grid object Grid topology; how landlab represents data; connectivity of grid elements.
• Introduction to Landlab data fields How Landlab stores spatial data on the grid; a little on naming conventions.
• Introduction to plotting output with Landlab The basics of plotting with Landlab; combining matplotlib and out plots; the all-powerful imshow_grid() function.
• Introduction to using the Landlab component library The basics of working with and coupling components, using diffusion, stream power, and a storm generator as examples.
• Using the gradient and flux-divergence functions Landlab as solving environment for staggered grid finite difference differential approximations; functions available to help you do this.
• Mapping values from nodes to links Options for getting data on links to nodes, nodes to links, etc.; min, max, and mean; upwinding and downwinding schemes; one-to-one, one-to-many, and many-to-one mappings.
• Setting boundary conditions on Landlab grids (several tutorials): How Landlab conceptualises boundary conditions; various ways to interact and work with them.
  • Raster perimeter
  • Based on Y-Y values
  • Watersheds
  • Voronoi
• Reading DEMs into Landlab Getting an ARC ESRI ASCII into Landlab; getting the boundary conditions set right.
• How to write a Landlab component What makes up a Landlab Component Standard Interface; how to make one for your process model.
