Question 1.
Define transmissibility.
Show hintHide hint
Think about how easily water can flow through an aquifer.
Question 2.
What does drawdown refer to?
Show hintHide hint
Consider what happens when you take water from a well.
3Question 3.
What does the Well Function (W(u)) represent?
- A measure of aquifer thickness
- A dimensionless function accounting for groundwater flow geometry
- The rate of water extraction from a well
Show hintHide hint
Think about what factors influence the shape of water movement in aquifers.
4Question 4.
True or False: The storage coefficient is indicative of the volume of water an aquifer can release or store.
- True
- False
Show hintHide hint
Consider why storage is critical in aquifer management.
Question 5.
If the well extracts water at 200 m³/day from an aquifer with transmissibility of 100 m²/day, determine how much drawdown occurs at a point 50 meters away after 2 hours of pumping.
Show hintHide hint
You may need to convert units into a compatible system before using the equations.
Question 6.
Discuss how variable storage coefficients affect the sustainability of groundwater resources in two different aquifer contexts.
Show hintHide hint
Think about how each coefficient influences water retention and release.
