Seep (hydrology)

A seep or flush[1] is a moist or wet place where water, usually groundwater, reaches the Earth's surface from an underground aquifer.

Seeps mostly occur in lower elevation areas because water runs downhill, but can happen higher up if the groundwater present is abundant enough.

This method can be useful for survival purposes and helps the local wildlife by adding another water source to the area.

[citation needed] 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.
