Question

Relation between volumetric and gravimetric water content

Answer 1

Relationship between gravimetric and volumetric water content

Soil water content is expressed on a gravimetric or volumetric basis. Gravimetric water content (θg) is the mass of water per mass of dry soil. It is measured by weighing a soil sample (mwet), drying the sample to remove the water, then weighing the dried soil (mdry).
