37.1.3. Permeability

Try these first

1. 1.

   What does permeability refer to in soils?

   Hint

   Think about water moving through sand vs. clay.

2. 2.

   How does low permeability affect liquefaction risk?

   Hint

   Consider what happens during an earthquake.

3. 3.

   What is permeability?

   • The ability of soil to drain water quickly
   • How easily water can flow through soil
   • The amount of water a soil can hold

   Hint

   Think about water flowing through different soil types.

4. 4.

   True or False: Lower permeability increases the risk of liquefaction in saturated soils.

   • True
   • False

   Hint

   Consider what happens when water cannot escape.

5. 5.

   Given a site with predominantly clay soil, design a drainage system to mitigate liquefaction risk during seismic activity.

   Hint

   Focus on how to manage water within the soil.

6. 6.

   Assess the impact of varying permeability in a sand and clay mixture during an earthquake scenario.

   Hint

   Consider interactions between soil types.
