2.4. Combining Darcy's Law with Continuity Equation

Try these first

1. 1.

   What soil type is best evaluated using a constant head permeameter?

   Hint

   Think about soil types and their grain sizes.

2. 2.

   What is the purpose of the continuity equation?

   Hint

   Recall how flow must balance in a closed system.

3. 3.

   What type of soil does the constant head method best apply to?

   • Fine-grained
   • Coarse-grained
   • Silty

   Hint

   Consider the flow rates of different soil types for this question.

4. 4.

   The Laplace equation is used to determine flow in which dimensional condition?

   • One-dimensional
   • Two-dimensional
   • Three-dimensional

   Hint

   Think about how dimensionality impacts fluid flow analysis.

5. 5.

   You are tasked with measuring the permeability of a new soil type using both constant and falling head tests. What considerations and calculations will you undertake?

   Hint

   Think about what each test measures and how to interpret measurements from different soil types.

6. 6.

   In a three-dimensional model of groundwater flow, explain how the results differ using numerical versus analytical methods.

   Hint

   Consider the strengths and limitations of different modeling techniques.
