The ephemeral nature of Granite Plateau Creek on the Mawson Plateau means the creek is usually a series of waterholes The travelling festival Burning Man was described by one scholar as the "very definition of ephemerality".
An ephemeral plant is a plant with a very short life cycle or very short period of active growth, often one that grows only during brief periods when conditions are ...
There is no clear demarcation between surface runoff and an ephemeral stream, [49]: 58 and some ephemeral streams can be classed as intermittent—flow all but disappearing in the normal course of seasons but ample flow (backups) restoring stream presence — such circumstances are documented when stream beds have opened up a path into mines or ...
Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by ...
Ephemeral waterfalls only flow after a rain or a significant snowmelt. [3] [4] [5] Plunge. Water descends vertically, losing contact with the bedrock surface.
The Doña Ana County Flood Commission in the U.S. state of New Mexico defines an arroyo as "a watercourse that conducts an intermittent or ephemeral flow, providing primary drainage for an area of land of 40 acres (160,000 m 2) or larger; or a watercourse which would be expected to flow in excess of one hundred cubic feet per second as the result of a 100 year storm event."

Intermittent rivers do not rely on, but may be supplemented, by stormwaters or other runoff from upstream sources. [10] Their channels are well-defined, [11] as compared to ephemeral streams, which may or may not have a defined channel, and rely mainly on storm runoff, as their aquatic bed is above the water table.
