35.3. Factors Affecting Specific Yield

Try these first

1. 1.

   What does specific yield measure?

   Hint

   Consider the definition of specific yield.

2. 2.

   True or False: Clay has a high specific yield.

   Hint

   Think about water drainage characteristics.

3. 3.

   What is the main factor that determines specific yield in soils?

   • Porosity
   • Grain size
   • Organic matter
   • Soil pH

   Hint

   Reflect on material composition and structure.

4. 4.

   True or False: Deeper saturation leads to a higher specific yield.

   • True
   • False

   Hint

   Consider the effects of gravity on water movement.

5. 5.

   You are assessing an aquifer composed of various soil types. Describe how you would analyze the specific yield using the factors discussed in this section.

   Hint

   Think about the practical steps you’d need to take to gather data.

6. 6.

   Evaluate how different seasonal temperatures could alter the specific yield in a region heavily reliant on groundwater for irrigation.

   Hint

   Consider the seasonal variations and their broader effects on aquifer yields.
