Calculation method

Calculation method

Specific Darcy flux (m/s)

Darcy magnitude q=K×hydraulic gradient, Q=q×area; homogeneous saturated steady flow.

Darcy discharge (m³/s)

Darcy magnitude q=K×hydraulic gradient, Q=q×area; homogeneous saturated steady flow.

Symbols and units
a
Hydraulic conductivity (m/s)
b
Hydraulic gradient magnitude (m/m)
c
Flow-normal area (m²)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Darcy magnitude q=K×hydraulic gradient, Q=q×area; homogeneous saturated steady flow. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
