Geomorphology Round Table - Spring 2017
Wilkinson 203, Tuesdays noon to 1pm
The Graded River

We will follow the evolution of writing and thinking on the "The Graded River" from Mackin's classic conception in the 1940s to today.  As we delve into the science, we will also discuss the readability and changing style of sceintific publications over the last 80 years.
