Definitions for "Gravitational Water"
Water that is not held by capillary action in soil but percolates downward by the force of gravity.
Related Topics: [ drainage] Often called "free water or excess water", this is water that will flow under the influence of gravity. It is not readily usable by plant roots because saturated conditions precludes necessary root aeration.
That portion of water in the soil not held strongly enough by adhesion to soil particles to resist the downward pull of gravity.
