Water content - Wikipedia
Volumetric water content, θ, is defined mathematically as: where is the volume of water and is equal to the total volume of the wet material, i.e. of the sum of the volume of solid host material (e.g., soil particles, vegetation tissue) , of water , and of air . Gravimetric water content[1] is expressed by mass (weight) as follows:
Understanding Soil Water Content and Thresholds for ...
The volumetric water content is the ratio of the volume of water to the unit volume of soil. Volumetric water content can be expressed as ratio, percentage or depth of water per depth of soil (assuming a unit surface area), such as inches of water per foot of soil.
Soil Water Content - an overview | ScienceDirect Topics
The volumetric water content is the soil–water content expressed as the volume of water per unit bulk volume of soil (Soil Science Society of America, 2008, p. 73). Tuller (2013) abbreviates the volumetric water content as θ .
How to convert gravimetric soil water content to volumetric ...
The amount of water or moisture in soil can be measured as either gravimetric soil water content (GWC) or volumetric soil water content (VWC). But what is GWC and VWC? And how do you convert GWC to/from VWC?
Quantifying Soil Water Content: Volumetric Water Content
2025年1月21日 · Volumetric water content (VWC) is a crucial measure in hydrology, soil science, and agriculture, as it quantifies the volume of water stored within a given volume of soil.
In basic terms, SWC is defined as the amount of water held in a certain mass or volume of soil. SWC indicates the quantity of water in the soil; however, it does not indicate the availability of this water to plants.
Determine the volumetric water content of soil by using direct (ovendry) and indirect (HPP) method. Oven dry method and heat pulse probe will be used to determine volumetric water content in different type of soil texture (Clay and Sand), and different vegetation plots.
