Think about why we need to understand water movement.
True or False: All flow lines are parallel to each other.
Consider how water diverges or converges in flowing situations.
A flow net is needed for a soil layer with well-defined permeable and impermeable boundaries. Construct a flow net sketch, marking equipotential and flow lines accurately.
Think about the distinct zones of flow and how they interact.
Explain how the height of standpipes at different boundaries can dictate the positions of equipotential lines in a flow net.
