Water retention curve
ID: water-retention-curve
A water retention curve (WRC), also known as a soil water characteristic curve (SWCC) or moisture retention curve, is a graphical representation that illustrates the relationship between the water content of soil and the soil's matric potential or suction (often measured in units such as centimeters of water or kilopascals). The curve helps to understand how much water a soil can hold at different levels of moisture and suction.
