17 Laminar vs. Turbulent Velocity Profile Comparison

18 Empirical relationships for mean flow velocity
Advantage – all we need is x-sect. A, and mean velocity How do we develop the relationship between stage and discharge?

19 Great photo of stream gauging…

20 The Manning Equation and Manning’s “n”

21 Salt Discharge Method

22 Consequences of RI>IC: Rise in Stage, Overbank Flooding

23 Rivers with impressive sediment loads – proglacial Kennicott River in full flood.

24 Floods – events of signif. morphologic change in rivers

25 Consequences of RI>IC: Rise in Stage, Overbank Flooding
