Question 1.
What does heterogeneity in aquifers refer to?
Show hintHide hint
Think about whether all parts of an aquifer behave the same.
Question 2.
Define capillary fringe.
Show hintHide hint
It’s related to how water moves vertically in soil.
3Question 3.
What impact does aquifer heterogeneity have on specific yield?
- It has no impact
- It can vary significantly between zones
- It only affects confined aquifers
Show hintHide hint
Remember that not all parts of an aquifer behave the same.
4Question 4.
True or False: Time-dependent drainage can lead to an overestimation of specific yield.
- True
- False
Show hintHide hint
Think about what happens after pumping stops.
Question 5.
Given two wells in an aquifer, one located in a compacted clay zone and the other in loose gravel, discuss how you would approach estimating the specific yield for each well.
Show hintHide hint
Consider how soil properties influence drainage.
Question 6.
A pumping test reveals a significant drop in the water level immediately after pumping starts, but the drawdown stabilizes only hours later. Analyze how you would interpret this data regarding time-dependent drainage.
Show hintHide hint
Think about how water levels behave over time.
