36.1.1. Coefficient of Permeability (k)

Try these first

1. 1.

   What does the Coefficient of Permeability (k) measure?

   Hint

   Think about how easily water flows through different materials.

2. 2.

   Name one factor that affects permeability.

   Hint

   Consider the physical characteristics of soil.

3. 3.

   What does the Coefficient of Permeability (k) indicate?

   • Rate of water flow
   • Water retention
   • Soil composition

   Hint

   Relate it to the movement of fluids in soils.

4. 4.

   True or False: Higher viscosity of a fluid leads to higher permeability.

   • True
   • False

   Hint

   Consider how thick fluids behave in porous media.

5. 5.

   If a sand aquifer has a permeability of 10^-4 m/s and a clay aquifer has 10^-9 m/s, calculate the ratio of permeability between the two.

   Hint

   Think about how to express permeability in terms of a ratio.

6. 6.

   Design a field experiment to determine permeability differences between urban soil and natural soil. Outline key considerations.

   Hint

   Reflect on environmental aspects that could affect your measurements.
