What is gradually varied flow?
Think about how flow changes in open channels.
What does a mild slope indicate?
Recall the relationship between normal and critical depth.
What is a mild slope in an open channel flow?
Refer to our classification discussion.
Is there a normal depth in a horizontal bed?
Consider the definition of horizontal bed channels.
Given a channel with a normal depth of 1 m and critical depth of 0.75 m, classify the channel type and provide reasoning.
Reflect on the relationships discussed between the depths.
If a river has a horizontal bed with a flow of 10 m³/s, discuss whether normal depth exists and justify your answer.
Consider how a horizontal slope affects flow.
