Permeability of soil and it’s measurement

The permeability of soil is soil property which describes quantitatively, the ease with which water flows through that soil. Soil consists of discrete particle. The void spaces between the particles

Water Content of soil and determination

Water content or moisture content of the soil is defined as the ratio of the weight of water to the weight of solids in a given mass of soil. It

What is void ratio?

Void ratio (e) is defined as ratio of the volume of voids to the volume of solids. $$e=\frac{V_v}{V_s}$$ where :\(V_v\) is volume of void, and \( V_s\) is volume of
