How to Determine the Soil Permeability Coefficient? (2)

Prior to the design and dimensioning of technical details, investigations according to [ASTM D2434] and/or [DIN18130-1:1998] should also be included. Their evaluation is based on the application of Darcy‘s law and, as a result, provides the permeability coefficient k.

k = \frac{v}{I}

Formula:

permeability coefficient k according to Darcy‘s law

v Filter velocity in the soil sample [m/s]

I Applied hydraulic gradient [-]
