Practice Questions

Question 1

Which of the following partial differential equations is commonly used to describe two-dimensional, steady-state groundwater flow in a homogeneous, isotropic confined aquifer, assuming Darcy's Law applies?

Question 2

A confined aquifer has a hydraulic conductivity ($K$) of $2 \times 10^{-4}$ m/s, a thickness ($b$) of $20$ m, and a specific storage ($S_s$) of $1 \times 10^{-6}$ $m^{-1}$. What is the storativity ($S$) of this aquifer?

Question 3

In the context of groundwater flow, what is the significance of the Reynolds number ($Re$) with respect to Darcy's Law?

Question 4

Which of the following boundary conditions represents a constant head (Dirichlet) boundary in a groundwater flow model?

Question 5

Consider a one-dimensional steady-state flow in a confined aquifer. If the hydraulic head at $x=0$ is $h_0$ and at $x=L$ is $h_L$, and the hydraulic conductivity is $K$, what is the analytical solution for the hydraulic head distribution $h(x)$?
