2 cards from this section. Quick, good the night before a test.
What defines gradually varied flow?
Think about how water deepens or shallows over distance.
What does a prismatic channel mean?
Consider the cross-section of the channel.
What is the primary characteristic of gradually varied flow?
Think about how water behaves in a very gently sloping channel.
True or False: A prismatic channel can have varying cross-sectional geometry.
Recall the definition of a prismatic channel.
Given a channel with a gradually varied flow with a mild slope, if the normal depth (y0) is greater than the critical depth (yc), explain how you would analyze the flow characteristics.
Consider how the Froude number might vary in this case.
Derive the differential equation expressing the relationship between energy slope, bottom slope, and water surface slope in a gradually varied flow scenario.
Focus on relating the forces and energy perspectives.
