Match the below open channel flow depths listed below with their

meaning$/$definition$.$

The depth attained when

friction exactly balances

gravity. Rarely happens in

actuality, but as engineers

we're happy to pretend like

it's the "norm" $.($omg$,$ do

you get the pun?$)$

Nice try, but there is no

such thing! I have attended

lecture religiously since the

Actual depth, $y$

beginning of the semester,

so I should know.

Critical depth, yc

Not a very popular depth

for the flow. Flow will go

quickly through this depth

as it transitions from one

state to another, trying to

forget that it ever

happened.

This depth simply $"$is what

it is$",$ which is Prof. Troy's

least favorite saying, unless

it's being applied to open

channel flow depths.

Uniform or "normal depth", yn

Stratified depth, ys
