1. 1.

   What is permeability?

   Hint

   Think about how water flows through different materials.

2. 2.

   Name two factors that affect permeability.

   Hint

   Consider the characteristics of materials.

3. 3.

   What does the term 'permeability' refer to?

   • Water's ability to evaporate
   • How easily liquids flow through soil
   • The weight of soil

   Hint

   Think about water moving through different layers.

4. 4.

   Darcy's law is applicable in what type of flow?

   • True
   • False

   Hint

   Consider flow conditions.

5. 5.

   If you have a confined aquifer with a storage coefficient of 10⁻⁴ and the hydraulic head increases by 2 m, what is the increase in storage volume for an area of 1 hectare?

   Hint

   Use the formula carefully considering units.

6. 6.

   A well in an unconfined aquifer discharges 0.5 m³/s with a hydraulic gradient of 0.02. If the saturation thickness is 5 m, what is the required permeability?

   Hint

   Calculate A using saturated thickness and consider the flow's area.
