WebCapillary action refers to the ability of water to travel up against the pull of gravity through a porous material. One common example of this action is water “wicking” up through a paper towel, following the direction of the paper fibers. WebCapillary force, also known as soil tension, refers to the soil’s ability to attract and hold water. Capillary force is quite small in almost most cases and is always ignored in water coning studies. The SA requires ongoing evaluation and reporting to the public on the effectiveness of the Department’s community engagement initiatives.
