For the InstructorThese student materials complement the Water Science and Society Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

Formative Assessment 3: Channel Systems
Write up a 1 page document (including your screen shots) answering the following questions.
1. Use Google Earth or a similar map program to find
a) a single-threaded channel with low sinuosity (relatively straight),Hint: These are relatively common.
b) a single-threaded channel with high sinuosity (lots of meander bends), Hint: Look in southern Alabama, Louisiana and Mississippi.
c) a braided channel with unvegetated bars and, Hint: Try British Columbia, Canada or Southern Alaska.
d) an anastomosing channel with vegetated islands. Hint: These may be the hardest to find. Look for multi-threaded reaches with large, vegetated bars. Try the Tonle Sap River in Cambodia, or the Murray River in southeastern Australia.
Submit screen shots (4 total) of the different channel types you find. If you don't find one or more of the river types in the area you are searching in the first few minutes, move to an entirely different geo-climatic zone and search for a few more minutes. What channel type do you come across most often? Which area(s) did you look at? What channel type do you come across most often? Approximately what is the stream order for each of the channels you captured as screen shots (i.e., are they first or second order channels? fifth order? tenth order?)? What other relevant observations did you make about the stream network while virtually flying around?
