Diadromous fishes migrate between freshwater and marine habitats to complete their life
cycle, a complexity that makes them vulnerable to the adverse effects of current and past …

Navigating trade-offs between meeting societal water needs and supporting functioning
ecosystems is integral to river management policy. Emerging frameworks provide the …

Reservoir-based hydropower systems represent key interactions between water and energy
systems and are being transformed under policy initiatives driven by increasing water and …

Dams and reservoirs are often needed to provide environmental water and maintain suitable
water temperatures for downstream ecosystems. Here, we evaluate if water allocated to the …

Intermittent water releases from hydropower plants, called hydropeaking, negatively affect
river biota. The impacts mainly depend on hydrological alterations, but changes in physical …

The hydrological characteristics of a river, including the magnitude and timing of high and
low flows, are important determinants of its ecological functioning. Climate change will alter …

Hypoxia, especially in the bottom water, is occurring in deep and stratified reservoirs
worldwide, threatening aquatic biodiversity, ecosystem functions and services. However …

Extreme hydro‐meteorological events such as droughts are becoming more frequent,
intense, and persistent. This is particularly true in the south central USA, where rapidly …

Selective withdrawal systems can take advantage of thermal stratification in reservoirs to
manage downstream temperatures. Selective withdrawal might also help adapt operations …

The relationships among drought, surface water flow, and groundwater recharge are not
straightforward for most forest ecosystems due to the strong role that vegetation plays in the …
