33.2. Types of Aquifers

Try these first

1. 1.

   What is an unconfined aquifer?

   Hint

   Think of the water table as the upper surface.

2. 2.

   What characterizes a confined aquifer?

   Hint

   What do we call the layers that confine it?

3. 3.

   What type of aquifer is characterized by a water table?

   • Confined
   • Unconfined
   • Perched

   Hint

   Think about the surface characteristics.

4. 4.

   True or False: Confined aquifers are always under pressure.

   • True
   • False

   Hint

   Consider the definition of confined.

5. 5.

   How would you design a sustainable water management plan considering the existence of all four types of aquifers?

   Hint

   Think of how each aquifer's characteristics would dictate its management needs.

6. 6.

   Analyze the impact of over-extraction of a confined aquifer and its cascading effects on surrounding unconfined aquifers.

   Hint

   Consider the relationship between pressure and recharge.
