Non‐perennial rivers and streams are ubiquitous on our planet. Although several metrics
have been used to statistically group or compare streamflow characteristics, there is …

Non-perennial river segments—those that recurrently cease to flow or frequently dry—occur
in all river networks and are globally more abundant than perennial (always flowing) …

Flowing waters have a unique role in supporting global biodiversity, biogeochemical cycles
and human societies,,,–. Although the importance of permanent watercourses is well …

In this chapter, the authors provide a comprehensive analysis and synthesis of the
interactions between important drivers and controls of hyporheic exchange and …

Over half of global rivers and streams lack perennial flow, and understanding the distribution
and drivers of their flow regimes is critical for understanding their hydrologic …

Rivers that do not flow year-round are the predominant type of running waters on Earth.
Despite a burgeoning literature on natural flow intermittence (NFI), knowledge about the …

Streamflow observations can be used to understand, predict, and contextualize hydrologic,
ecological, and biogeochemical processes and conditions in streams. Stream gages are …

In these times of strong pressure on aquatic ecosystems and water resources due to climate
change and water abstraction, intermittent rivers and ephemeral streams (IRES)(rivers that …

Flowing stream networks extend and retract as their surrounding landscapes wet up and dry
out, both seasonally and during rainstorms, with implications for aquatic ecosystems and …

Intermittent rivers and ephemeral streams (IRES) are now recognized to support specific
freshwater biodiversity and ecosystem services and represent approximately half of the …
