1.1. Steps of Construction

Try these first

1. 1.

   What is a flow net?

   Hint

   Think about how we visualize water movement.

2. 2.

   Identify one boundary condition in flow net construction.

   Hint

   Consider what happens when soil is saturated.

3. 3.

   What is the purpose of flow nets in soil mechanics?

   • To visualize flow patterns
   • To measure soil density
   • To enhance soil color

   Hint

   Think about why we need to understand water movement.

4. 4.

   True or False: All flow lines are parallel to each other.

   • True
   • False

   Hint

   Consider how water diverges or converges in flowing situations.

5. 5.

   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.

   Hint

   Think about the distinct zones of flow and how they interact.

6. 6.

   Explain how the height of standpipes at different boundaries can dictate the positions of equipotential lines in a flow net.

   Hint

   Consider the relationship between hydraulic head and water flow.
