Definitions for "Intermittent stream"
A watercourse that flows in a well-defined channel for 20 - 90% of the year during normal rainfall conditions.
A stream that dries up during periods of low rainfall, flowing only during the wetter part of the year.
A flow that occurs only seasonally when the water table is at the maximum level. The drainage network is composed of ephemeral, intermittent and perennial streams and the network expands during rainstorms and extends to limits affected by antecedent conditions especially antecedent moisture. Flow may occur along intermittent streams for several months each year but will seldom occur when the water table is lowered during the dry season ( Thomas and Goudie 2000).
