4 cards from this section. Quick, good the night before a test.
What is the role of equipotential lines in a flow net?
Think about water levels in standpipes.
What is a flow line?
It's related to the direction of water flow.
What do equipotential lines indicate?
Think about the meaning of 'equal' in terms of head.
True or False: Flow lines are always perpendicular to equipotential lines.
Recall the definitions of flow lines and equipotential lines.
Given a soil profile with one permeable and one impermeable layer, draw the expected flow net and identify the boundary conditions.
Think about how water can or cannot move through these layers.
How might the flow net change if the direction of water flow is reversed in a soil with multiple layers? Discuss the implications.
Consider how the properties of flow and head define the net shape.
