Introduction
BurnedAreaM.jpg
This lab is appropriate for advanced undergraduates and graduate students majoring in earth science/engineering.


We will use Landlab to generate a grid, use two different landscape evolution models (LEMs) to evolve a synthetic landscape, apply stochastic wildfires that increase erodibility, and plot various maps and graphs. Though no real-world data are used, the landscape relief is statistically realistic and roughly approximate to the Wasatch mountains in Utah.

Classroom organization
This Jupyter Notebook is best for people who already have a conceptual understanding of earth surface processes and want to learn how these apply to numerical modeling, landscape evolution, and sediment flux. Although no Python skills are required to run the notebook, those with an intermediate understanding of Python will be able to learn more by reading the code.


This lab can be run on the CSDMS JupyterHub. (Follow the instructions here to create an account if you don't already have one: https://csdms.colorado.edu/wiki/JupyterHub.) Run the Jupyter Notebook by clicking the "start" link under the Run online heading at the top of this page.

If you have questions, please contact us through the CSDMS Help Desk: https://github.com/csdms/help-desk.
