Seepage: Steady State Flow of Water
If fluid pressures in a soil deposit are uniformly increasing with depth according to then hydrostatic conditions will prevail and the fluids will not be flowing through the soil. is the depth below the water table. However, if the water table is sloping or there is a perched water table as indicated in the accompanying sketch, then seepage will occur. For steady state seepage, the seepage velocities are not varying with time. If the water tables are changing levels with time, or if the soil is in the process of consolidation, then steady state conditions do not apply.

Famous quotes containing the words steady, state, flow and/or water:
“Wild as it was, it was hard for me to get rid of the associations of the settlements. Any steady and monotonous sound, to which I did not distinctly attend, passed for a sound of human industry.... Our minds anywhere, when left to themselves, are always thus busily drawing conclusions from false premises.”
—Henry David Thoreau (1817–1862)
“Only by the supernatural is a man strong; nothing is so weak as an egotist. Nothing is mightier than we, when we are vehicles of a truth before which the state and the individual are alike ephemeral.”
—Ralph Waldo Emerson (1803–1882)
“Parents ought, through their own behavior and the values by which they live, to provide direction for their children. But they need to rid themselves of the idea that there are surefire methods which, when well applied, will produce certain predictable results. Whatever we do with and for our children ought to flow from our understanding of and our feelings for the particular situation and the relation we wish to exist between us and our child.”
—Bruno Bettelheim (20th century)
“Lord, crack their teeth! Lord, crush these lions’ jaws!
So let them sink as water in the sand;
When deadly bow their aiming fury draws,
Shiver the shaft ere past the shooter’s hand.
So make them melt as the dishoused snail”
—Bible: Hebrew Psalm LVIII (Paraphrased by the Countess of Pembroke)
