Held water
Short answer
Held water is water retained in soil by molecular attraction and surface tension, so it cannot drain by gravity. It includes adsorbed and capillary water and does not flow freely, unlike free (gravitational) water.
Define held water.
Held water is the water that is held in the soil by molecular attraction (adsorption) and surface tension around the soil particles, so that it is not removed by gravity drainage. It includes adsorbed (hygroscopic) water and capillary water, and it does not flow freely under gravity. In contrast, free (gravitational) water drains under gravity and is the part that flows under a hydraulic gradient.
