What best defines an intermittent stream?

An intermittent stream is characterized by its flow occurring only during certain seasons or periods of time, rather than continuously throughout the year. This pattern commonly happens in response to seasonal rainfall, melting snow, or variations in groundwater levels. During dry periods, such streams may fall dry, which distinguishes them from perennial streams that maintain a constant flow year-round. Understanding the behavior of intermittent streams is crucial for water management, as they play a significant role in the ecosystem, impacting wildlife habitats and local water supplies during their active periods. This definition clearly highlights the intermittent nature of such streams, setting them apart from streams that are always dry or perpetually flooded.
