Beyer Nomogram for Determining the Soil Permeability Coefficient

As the solution to his determined interrelations, Beyer provides an easy-to-handle nomogram, from which you can directly read off the water permeability for sands and gravels [Beyer64].

However, this method does not take sufficient account of decisive influencing factors (as e.g. the given bedding density). Thus, reliable data for the individual case of application can only be gathered by means of a test arrangement for the determination of the water permeability coefficient k according to [ASTM D2434] and/or [DIN18130-1:1998].
