Introduction

Landlab is an open-source Python-language package for numerical modeling of Earth surface dynamics. Landlab was designed for disciplines that quantify Earth surface dynamics such as geomorphology, hydrology, glaciology, and stratigraphy. It can also be used in related fields. Scientists who use this type of model often build their own unique model from the ground up, re-coding the basic building blocks of their landscape model rather than taking advantage of codes that have already been written. Landlab saves practitioners from the need for this kind of re-invention by providing standardized components that they can re-use. Detailed information about Landlab can be accessed at https://landlab.readthedocs.io/en/master/

Classroom organization
In this lab, we will use different Landlab components for modeling earth surface processes. This lab includes two Jupyter Notebooks. One illustrates running the deAlmeida overland flow component in an extremely simple-minded way on a real topography, then shows it creating a flood sequence along an inclined surface with an oscillating water surface at one end. The other one illustrates how you can use Landlab to construct a simple two-dimensional numerical model on a regular (raster) grid, using a simple forward-time, centered-space numerical scheme.


You can create an account at CSDMS JupyterHub and test the Jupyter Notebook for this lab. Please follow the instruction in the "Lab Notes" section. If you are a faculty at an academic institution, it is possible to work with us to get temporary teaching accounts. Work directly with us by emailing: csdms@colorado.edu.

Learning objectives
Skills
  • Learn to use deAlmeida Overland Flow Landlab component to create a flood sequence.
  • Learn how to use Landlab to construct a simple two-dimensional numerical model on a regular (raster) grid.
Key concepts
  • Erosional degradatoin of an earthquake fault scarp
  • Geomorphic diffusion for landform evolution
  • Flood sequence along an inclined surface

Lab notes
You can follow the steps below to test and run the Jupyter Notebooks on the CSDMS JupyterHub server for this lab.

1. Create a free account on the CSDMS JupyterHub at https://csdms.rc.colorado.edu/hub/signup, providing a username and password -- they can be whatever you like

2. Request authorization for your new account through the CSDMS Help Desk at https://github.com/csdms/help-desk/issues/new?assignees=mdpiper&labels=jupyterhub&template=new-csdms-jupyterhub-account.md&title=CSDMS+JupyterHub+account -- if you don't already have a GitHub account, you'll be asked to make one

3. Once approved, run Jupyter Notebooks by clicking on "start" under the "Run online" section (grey table at the top of this lab page).
