Hydraulic Conductivity Ranges of Various Soil Types
Representative Values for Hydraulic Conductivity of Soils

Typical Permeability Classes

Notation and Units
Metric and Imperial Units
The above values have been provided with both imperial and metric units. As with all calculations care must be taken to keep consistent units throughout. A guide to Soil Types has been provided by StructX and additional information has been provided below.
Notation
- k = hydraulic conductivity, ft/s or m/s
