In soil mechanics, seepage is the movement of water through soil. If fluid pressures in a soil deposit are uniformly increasing with depth according to u = ρ w g z w {\displaystyle u=\rho _{w}gz_{w}} , where z w {\displaystyle z_{w}} is the depth below the water table, then hydrostatic conditions will prevail and the fluids will not be flowing ...

Seep is often used in environmental sciences to define an exfiltration zone (seepage zone) where contaminated water, e.g., from waste dumps, leaves a waste system area. Seeps are often important smaller wildlife water sources, and indicated by lower riparian vegetation.
Silt fence installed up-slope of a vegetated stream buffer. A silt fence, sometimes (misleadingly) called a filter fence, [1] is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment (loose soil) in stormwater runoff.
A simplified version of the Emerson soil dispersion test [3] can be completed in the field on a 20-minute to two-hour timescale. Laboratory tests used to diagnose a soil as dispersive focus on the cation exchange capacity of a soil sample and its cation breakdown. Soil cations are dominated by Ca 2+, Mg 2+, K +, and Na +, as well as H + in ...
Internal erosion is the formation of voids within a soil caused by the removal of material by seepage. [1] It is the second most common cause of failure in levees and one of the leading causes of failures in earth dams, [2] responsible for about half of embankment dam failures. [3]
Subirrigation also known as seepage irrigation, is a method of irrigation where water is delivered to the plant root zone. The excess may be collected for reuse. The excess may be collected for reuse.
SEEP2D is a 2D seepage analysis program written by Dr. Fred Tracy of the United States Army Corps of Engineers. The program is used to analyze water seepage, typically through dams and levees or under sheet piles. "The model is internationally known in the engineering community as a model for complicated seepage analysis of dams and levees."
