Question 1.
Define specific yield in your own words.
Show hintHide hint
Think about what happens when you pour water into sand.
Question 2.
What is the formula for calculating specific yield?
Show hintHide hint
Remember, it involves both volume and water.
3Question 3.
What is specific yield?
- The total void space in soil
- Water that can drain due to gravity
- Water held against gravity
Show hintHide hint
Think about the water's movement through soil.
4Question 4.
True or False: Specific yield and porosity are the same.
- True
- False
Show hintHide hint
Consider the role of gravity in their definitions.
Question 5.
Estimate the specific yield of a sandy aquifer that has 80% porosity and holds 120 liters of water in its pores. How much water can be drained?
Show hintHide hint
First, identify how to relate the porosity and specific retention.
Question 6.
An aquifer has an average specific yield of 15%. If the area of the aquifer is 5000 m², how much water can be stored if the water table drops by 2 meters?
Show hintHide hint
Use the formula mentioned to calculate the drained volume based on dimensions.
