Base flow
Base Flow
Base flow (pronounced: /beɪs floʊ/), also known as groundwater flow, is the portion of the streamflow that is sustained between precipitation events, fed by groundwater. The water in the stream or river that comes from the base flow is often derived from sources such as seepage from the ground, springs, or natural reservoirs.
Etymology
The term "base flow" is derived from the English words "base", meaning the bottom part or a foundation, and "flow", meaning to move along in a steady, continuous stream. It was first used in hydrology to describe the steady, foundational flow of water in a stream or river.
