Darcy Flow

Parameters

Hydraulic Conductivity k:

1.0 × 10^-4 m/s

Head Loss Δh:

2.0 m

Flow Length L:

4.0 m

Cross-sectional Area A:

0.20 m²

Key Results

Hydraulic Gradient i

Darcy Flux q

Discharge Q

Q = k A Δh / L

Interpretation: Head is the height water rises in a standpipe above a common datum. Water flows through the soil from the higher head on the left to the lower head on the right, and the drop over the specimen length gives the hydraulic gradient i = Δh / L.
