Result Interpretation

Seepage Quantity Through Dam Foundation (Confined/Unconfined Aquifer) calculator computes Seepage Quantity per Unit Width in m³/(s·m) using the defined engineering formula and the input values provided. Seepage Quantity per Unit Width is expressed in m³/(s·m). No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Hydraulic Conductivity = 1.0E-6
  • Upstream Total Head (above datum) = 30
  • Downstream Total Head (above datum) = 2
  • Length of Seepage Path (foundation flow length) = 50

Expected Result:

  • Seepage Quantity per Unit Width = 8.72E-7

Engineering Interpretation:

Under the given input conditions, the calculated result is: Seepage Quantity per Unit Width = 8.72E-7 m³/(s·m).

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
