Seepage

seepage
(1) The escape of water downward through the soil. (2) The emergence of water from the soil along an extensive line of surface in contrast to a spring where the water emerges from a local spot.

Seepage: Percolation of water through the soil from unlined canals, ditches, laterals, watercourses, or water storage facilities.

seepage The percolation or trickling of water (or other liquid) through the soil from unlined channels, ditches, watercourses, and water storage facilities. A seepage lake has no visible surface inflow.

Seepage: (1) The slow movement of water into or out of a body of surface or subsurface water.

Seepage Pits: A hole, shaft or cavity in the ground used for storage of liquids, usually in the form of leachate, from waste disposal areas. The liquid gradually leaves the pit by moving through the surrounding soil.

SEEPAGE LENGTH
In sediment basins or ponds, the length along the pipe and around the anti-seep collars that is within the seepage zone through an embankment.
SENSITIVE STREAM OR SUBWATERSHED ...

Seepage Velocity
The rate of discharge of ground water per unit area of a porous medium measured at right angle to the direction of flow (Lohman and others, 1972).
Selective Non-Catalytic Reduction ...

Reverse seepage of water in a distribution system.
Bacteria
Microscopically small single-cell organisms, that reproduce by fission of spores.

Examples: San Ysidro Hot Springs, San Ysidro, New Mexicospring (seepage)A spring where water percolates from numerous small openings in permeable materials and where the discharge rate is usually low. Example: Olancha, California.

It is supported by groundwater seepage into the channel. (2) The fair-weather or sustained flow of streams; that part of stream discharge not attributable to direct runoff from precipitation, snowmelt, or a spring.

Groundwater disposal: Wastewater that is disposed of through the ground either by injection or seepage.

Tires can be used as indoor planters if they are placed on heavy plastic or lined with plastic to prevent water and dirt seepage. Grow lights can be placed over the tire structure to extend light during winter months.

Hydraulic Cycle: The continuous circulation of water between the earth and the atmosphere, through condensation, precipitation, runoff, percolation, evaporation, transpiration, groundwater storage and seepage, ...

Percolation: 1. The movement of water downward and radially through subsurface soil layers, usually continuing downward to ground water. Can also involve upward movement of water. 2. Slow seepage of water through a filter.

A serious environmental problem arises when the aquifer is contaminated by the seepage of sewage or toxins from waste dumps. If the groundwater in coastal areas is over-used salt water can seep into the aquifer.
