In streams, biofilms should be depicted as ecosystem engineers as they stabilize and fertilize sediments. Their development is thus critical for river ecosystems, particularly in glacier floodplains, where sediments tend to be unstable and nutrient‐limited.

An example of a zoning policy whereby development has been focused onto flood safe areas combined with land‐use changes.

Artificial light at night can occur as a form of environmental pollution, light pollution, which also affects aquatic systems. We identify a knowledge gap of insufficient data regarding the status quo of aquatic light pollution and provide a route to fill this gap with in‐situ measurements.

Power‐sensitive resilience of social–hydrological systems: five definitional questions with political implications derived from critiques of the resilience concept.

Large wood (LW) in rivers can provide a range of benefits. This includes improving the ecological integrity of rivers, reducing flood risk and managing sediment. Numerical hydraulic and hydrological models are used to predict the effects of LW. However, the suitability of approaches to LW modeling and therefore guidance, remain uncertain.

For many human populations around the world, river flows are linked to livelihood, identity, sense of place, religious beliefs and ceremonies, language systems, or educational practices. These embedded, reciprocal, and constitutive relationships between humans and rivers remain poorly understood, but can be critically important to assessment and implementation of environmental flows

The connection between the weakening intensity of the terrestrial water cycle and the notion of human well‐being as a declining asset.

Following Hurricane Katrina in August 2005, residents of Jefferson Parish, Louisiana, especially children and older people, are brought to an elevated bridge area by boat (photograph by Win Henderson: Available at: https://commons.wikimedia.org/wiki/File:FEMA_-_14535_-_Photograph_by_Win_Henderson_taken_on_08-31-2005_in_Louisiana.jpg (accessed at May 9, 2019).).

Velocity is a dynamic and highly localized component of river discharge. Areas of intense velocity can create barriers to migration for fish. But, understanding relations between river discharge and the biological implications of local hydraulic barriers has only recently become possible. High resolution digital elevation models derived from drones are useful in characterizing these hydraulic features at the scale at which migrating fish experience them. Below is a an orthorphoto mosaic of study reach overlaid with modeled velocity (m/s) at survey discharge.

Simulation modeling of nonmarket water exchanges: Exchange strategies reach different stable arrangements depending on the population of partners.

Sixty percent of Australia's wastewater treatment plants use waste stabilization pond (WSP) technology for treatment. WSP systems are most commonly used in regional and remote areas.
