The surface of the water in the supersaturated soil is known as the “water-table” and is exemplified in water standing in a well.
A member: I should think that would depend quite a little on the height of the water-table.
Cellars were not practical in the low-lying areas, for in wet weather the water-table is level with the ground.
If you were planting on land where the water-table is low, you would leave more tap-root?
Now, we know that, in almost all New England, the water-table is many feet below the surface.
Would you feel like saying that a water-table at 24 inches was neither too low nor too high?
The water-table should be at least two feet from the surface.
Mr. Lake: But the capillarity of the soil provides water for the tree above the water-table.
Centrifugal pumps usually are set in dry wells a few feet above the water-table.
Wren told him 'water-table,' which he then inserted in the text, striking out the marginal note.
|water table |
The upper surface of an area filled with groundwater, separating the zone of aeration (the subsurface region of soil and rocks in which the pores are filled with air and usually some water) from the zone of saturation (the subsurface region in which the pores are filled only with water). Water tables rise and fall with seasonal moisture, water absorption by vegetation, and the withdrawal of groundwater from wells, among other factors. The water table is not flat but has peaks and valleys that generally conform to the overlying land surface. Compare potentiometric surface.
The depth (measured from the surface of the Earth) at which underground water is first encountered.
