35.1. Definition of Specific Yield

Try these first

1. 1.

   What is Specific Yield?

   Hint

   Think about the ratio of draining water to total volume.

2. 2.

   If a specific yield is 0.15, what does that mean?

   Hint

   Convert that to a percentage for clarity.

3. 3.

   What does Specific Yield quantify?

   • Total volume of water in aquifer
   • Volume of water that can be extracted
   • Porosity of soil

   Hint

   Focus on what Specific Yield is responsible for determining.

4. 4.

   True or False: Specific Yield and Porosity are the same.

   • True
   • False

   Hint

   Think about what each term measures.

5. 5.

   Calculate the Specific Yield if an aquifer has a volume of 50,000 m³ and can yield 10,000 m³ of water.

   Hint

   Use the definition and formula of Specific Yield.

6. 6.

   Discuss factors that might affect Specific Yield and how these could influence groundwater extraction planning.

   Hint

   Consider both physical and environmental factors.
