# Permeability Coefficient

Written by Jerry Ratzlaff on . Posted in Geotechnical

Permeability Coefficient, abbreviated as K, also called coefficient of permeability, is the measure of how much water can easily flow through the soil.

## formulas that use Permeability Coefficient

 $$\large{ k = n \; v }$$

### Where:

$$\large{ k }$$ = permeability coefficient

$$\large{ n }$$ = porosity

$$\large{ v }$$ = velocity of water flowing through pores
