Much of the petroleum discovered in California during the 19th century was from observations of seeps. [32] The world's largest natural oil seepage is Coal Oil Point in the Santa Barbara Channel, California. [33] Three of the better known tar seep locations in California are McKittrick Tar Pits, [34] Carpinteria Tar Pits and the La Brea Tar ...
Typically, porous soils are removed before compacted clay is applied to the bed and sides of a canal. [3] Another simple method of canal lining with soils entails applying a layer of compacted silt on top of the subgrade of the canal. [3] The use of soils as canal linings is efficient for controlling seepage, but not effective against weed ...
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.

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.
