Question 1

What does the Theis equation calculate?

  • Storage capacity
  • Drawdown
  • Fluid viscosity

💡 Hint: Focus on what happens to water levels when pumping occurs.

Question 2

True or False: Transmissibility indicates how easily water can move through an aquifer.

  • True
  • False

💡 Hint: Think about the flow dynamics of groundwater.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a scenario where a well shows a drawdown of 4 meters after 10 hours of pumping at a rate of 50 m³/day. If the transmissibility of the aquifer is 200 m²/day, estimate the distance 'r' from the well that would yield the observed drawdown using the Theis equation.

💡 Hint: Break down each piece of the equation and consider how you’d isolate r.

Question 2

Using empirical data from aquifer tests, describe how you would create a time-drawdown curve and calculate the well constants.

💡 Hint: Remember, the curve serves as a visual guide to understanding aquifer behavior.
