Ephemeral streams are water channels that only flow during certain times of the year, typically during periods of increased precipitation or snowmelt. These streams are characterized by their intermittent flow patterns, which can vary in frequency, duration, and intensity. Ephemeral streams are important components of freshwater ecosystems, providing habitat for diverse plant and animal species. Research in this area often focuses on understanding the ecological importance of ephemeral streams, as well as assessing their vulnerability to climate change and human impacts. Additionally, studies may explore the hydrological dynamics of ephemeral streams and their role in nutrient cycling and sediment transport in watershed systems.
