Please read Chapter 2 of Chanson (2004). The chapter covers' Fundamental Equations' in open channel flow, starting with conservation of mass, momentum and energy. Make sure you know what all the symbols are and don't get confused between Chanson's symbology and Dingman's.  I've assigned this chapter for you to digest first as it is more concise then Dingman's (2008) Chapter 4. We will read Dingman's (2008) Chapter 4 for Thursday and he will cover many of the same principles but with slightly different derivations and explanations.

Note: You don't need to vote for lecture topics as we will cover the whole chapter.
