Soil Mechanics for Unsaturated Soils
The phreatic line resulting from the saturated-unsatu- rated flow model is in close
agreement with the empirical free surface from a conventional flownet
construction. This observation supports the assumption that the empirical free
surface is ...

Seepage, Drainage, and Flow Nets
4.5 UNCONF1NED FLOW SYSTEMS (Phreatic Line Unknown) 1n the examples
given in Sec. 4.4 the line of saturation, or phreatic line, is known in advance,
which makes the procedure for obtaining the flow nets simpler than it is for cross
...

Soil Mechanics and Foundations
The phreatic line or seepage line is defined as the line within a dam section
below which there are positive hydrostatic pressures in the dam. The hydrostatic
pressure on the phreatic line itself is atmospheric. The phreatic line can be
located by ...

Carbonate Sedimentology and Petrology
Waters in these large phreatic lenses not only percolate down from the vadose
zone, but also arrive at the water table directly from lakes, swamps, rivers and via
vadose flow through fissures. Because the phreatic waters are from different ...
