Groundwater Discharge by Darcy's Law
EasyDarcy's lawgroundwater
Using Darcys law, what is the groundwater discharge for hydraulic conductivity k = 1 × 10-4 m/s, hydraulic gradient i = 0.02, and gross cross-sectional flow area A = 100 m2?
- A2 × 10⁻⁶ m³/s
- B2 × 10⁻⁴ m³/s
- C0.002 m³/s
- D0.02 m³/s
Show solutionHide solution
Answer: B. 2 × 10⁻⁴ m³/s
Darcy discharge is Q = kiA = (1 × 10⁻⁴)(0.02)(100) = 2 × 10⁻⁴ m³/s. Hydraulic gradient is dimensionless.
