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.

“What do we mean by patriotism in the context of our times? I venture to suggest that what we mean is a sense of national responsibility ... a patriotism which is not short, frenzied outbursts of emotion, but the tranquil and steady dedication of a lifetime.”
—Adlai Stevenson (19001965)

—William Wordsworth (17701850)
“Our sense of these things changes and they change,
Not as in metaphor, but in our sense
Of them. So sense exceeds all metaphor.
It exceeds the heavy changes of the light.
It is like a flow of meanings with no speech
And of as many meanings as of men.”
—Wallace Stevens (18791955)
“I think of the nestling fallen into the deep grass,
The turtle gasping in the dusty rubble of the highway,
The paralytic stunned in the tub, and the water rising,
All things innocent, hapless, forsaken.”
—Theodore Roethke (19081963)
