If you are interested in my online Earth Science course materials for teachers, please find a version of them at
If you are looking for the Stream Runoff Algorithm linked to from my book “Learning to Read the Earth and Sky”, you can find that at

or, there are some expanded notes for this exercise, along with the link, available at
