WebPermeability is the ease with which water can flow through the soils. Permeability of the soil in its natural deposits is highly influenced by its natural structural factors such as its non-homogeneity and stratification. WebSoil mechanics is critical in civil engineering as it describes the principles that govern the way civil infrastructure projects such as buildings, bridges, tanks, embankments, dams, and tunnels, are supported by the soil.

WebFig.17.1. Flow of water a different type of soils Darcy’s Law. Velocity (v) of flow is proportional to the hydraulic gradient (i).Thus, V = Ki (17.1) where k is the coefficient of permeability (cm/sec) or hydraulic conductivity. If i is equal to one, the v = k.Thus, coefficient of permeability is velocity of water for unit hydraulic gradient.
