The lowest elevation a stream channel's floor can reach at a given locality.
On a chart the base level indicates where a cycle starts as measured vertically. Two cycles may have a different base level and amplitude even though their phase, period, and frequency are equal.
A MAP parameter that sets the level on the digital amplitude scale below which no stimulation is sent to the recipient. The digital amplitude scale is from 1 to 150. The Loudness Growth Function starts at Base Level.
The lower limit of erosion by a stream. Sea level is the ultimate base level. However, lakes can serve as a temporary base level in upstream areas.
The lowest level to which a stream can erode the channel through which it flows, generally equal to the prevailing global sea level.
The lowest level to which a stream can erode its bed. The ultimate base level of all streams is, of course, the sea.
The lowest level to which a land surface can drop by action of water; the permanent base level is sea level.
the level of the body of water into which a stream flows
An elevation in a stream channel that is fixed over the long term by being relatively unerodable, such as a dam, or not subject to erosion, such as sea level.
The lowest elevation to which a stream is capable of eroding the landscape; the lowest elevation or mouth of a drainage system; usually refers to sea level, or localized on a lake
The level below which dry lands cannot be eroded.
The level below which a stream cannot erode: usually sea level, sometimes locally the level of a lake or resistant formation.
In general, the lowest point in the water table in a given area. Water in the area flows toward this destination by gravity and hydrostatic pressure.
The subterranean elevation below which a stream cannot vertically erode sediment. For many streams this hypothetical elevation is sea-level.
The base level of a river or stream is the lowest point to which it can flow, often referred to as the 'mouth' of the river. For large rivers, sea level is usually the base level, but a large river or lake is likewise the base level for tributary streams. A rather rare exception can be seen in the Jordan River, for which the base level is the Dead Sea, 417 m below modern sea level.
