Module 12 - River Evolution Reading

Please read Chapter 12 in its entirety. For these last few chapters, we will continue to just read and discuss as opposed to watching YouTube lectures and doing new assignments. In part, these are synthesis chapters that help you put a lot of the pieces we've covered together and you learn a lot from having to explain your understanding of these concepts to each other. Also, I don't want to assign too much new lecture stuff to watch while you are starting to work on your final projects. YES, I expect you to start pulling together some basics on your projects. At the end of Monday's class, we will talk a little bit more about your final projects.

For Monday (March 28) our 2022 class will meet and each of you will be responsible for presenting some mini lectures to the rest of us to explain River Evolution. I have assigned sections to each of you in italics below. Most of these are individual presentations and a few of these at end where we pull it together for how to do your projects will be group. These don't need to be perfectly polished presentations. Just pull together visual aides from the figures in the book (feel free to bring in other real examples) and help the rest of us understand the sections you are responsible for.
