Question 1.
What is drawdown?
Show hintHide hint
Consider the static water level before pumping.
Question 2.
What does the variable Q represent in the Theis Equation?
Show hintHide hint
Think about the flow rate of water.
3Question 3.
What does the Theis Equation primarily help us calculate?
- Aquifer permeability
- Drawdown and transmissibility
- Well depth
Show hintHide hint
Focus on the purpose of the equation.
4Question 4.
True or False: The well function W(u) accounts for time and distance effects.
- True
- False
Show hintHide hint
Think about what 'function' means in this context.
Question 5.
A well pumps at 0.015 m³/s, and the drawdown is observed as 4 meters in 2 days at a distance of 25 meters. Calculate the transmissibility using the Theis Equation.
Show hintHide hint
Use the formula for W(u) and calculate the values stepwise.
Question 6.
During a field study, a monitored well shows an initial static water level of 10m. After 12 hours of pumping, the level drops to 7m. The transmissibility calculated is 12 m²/day. What is the well function W(u)?
Show hintHide hint
Remember to use the drawdown and time in the correct units.
