Capillary Action and Soil
Date: Winter 2012-2013
Why is capillary action important in soil? Why would it be important to parts of a city?
Thanks for the question. Capillary action is important in soils since it is how plants transport water from their roots to their leaves. Capillary action is also important in soils since it slows down the flow of water through a soil. The slow absorption of water by soils can be cause of a flash-flood. The absorption of water by soils is important to a city since a city may have little exposed soil and much concrete or asphalt. I have read that runoff from cities is due to the lack of soil being able to absorb rain water.
I hope this helps. Please let me know if you have any more questions.
