Summary: Combining different background datasets in species distribution models can improve predictions of riparian plant distributions, capturing the effects of both hydrologic and climatic predictors. This approach provides more accurate information to guide management decisions and can be applied to species from various specialized habitats.

Summary: By utilizing annual flow duration curves (FDCs) and the modified Mood's median test (MMMT), this study investigates the significance of hydrologic alteration and its impact on hydrologic regimes. Dams are found to be the main cause of hydrologic disturbance, affecting low flows more than high flows.

Summary: The strength of interactions between plants and river processes is influenced by plant traits and fluvial conditions. The differential effects of Tamarix and Populus on hydraulics, sediment transport, and river morphology were examined using flume, field, and modelling approaches. Differences in crown morphology, stem density, and flexibility favored aggradation associated with Tamarix, leading to faster geomorphic adjustments compared to Populus. These findings provide a basis for predicting changes in alluvial riverine systems and highlight the importance of considering plant traits and community structure in addition to flow and sediment supply.

Summary: The interaction between riparian vegetation and river processes is influenced by plant traits and fluvial conditions, with Tamarix and Populus species having differing effects on hydraulics, sediment transport, and river morphology. Differences in plant traits between the two species influence river adjustments at various scales, highlighting the importance of considering plant characteristics in river management and invasive species control.

Summary: In semi-arid regions, riparian forests rely on alluvial groundwater to supplement local precipitation. This study found that riparian cottonwood forests have a consistent uptake rate of alluvial groundwater, enabling them to maintain high rates of water use and productivity even in warm and dry summers. This is attributed to perennial river flow, adaptations of cottonwoods to the riparian hydrology and climate, and environmental flow operations. The findings provide valuable information for water managers to regulate river flows and support healthy downstream riparian ecosystems.

Summary: Recent studies have shown links between hydrologic changes and fish populations in U.S. rivers, highlighting the importance of fish-flow relationships and adverse impact thresholds for environmental flow conservation and regulations. Although relationships have been established in individual rivers, research on large basins or national scale is lacking. Through analysis of a nationwide dataset, strong empirical relationships between hydrologic metrics and native fish richness have been established, serving as guidelines for science-based management.

Summary: The relationship between data length and evaluation of hydrological alteration is uncertain. The study applied the length of record (LOR) method to analyze the impact of different data lengths on Indicators of Hydrologic Alteration (IHA) evaluation in the Jinsha River. Results show that different indicators may require different lengths of data support, and a logarithmic correlation was found between LOR results and the coefficient of variation (CV) of IHA statistics.

Summary: This study quantified the relationship between riparian vegetation and river flow in the arid Ejina Delta using regression analysis and NDVI and hydrological data. The results showed that the riparian vegetation cover expanded and the SMN increased. The annual RV condition was well estimated by incorporating previous RV conditions and subsequent water-year runoffs.

Summary: This study used Landsat satellite imagery to assess the historical ecosystem productivity of a riparian cottonwood forest in southern Alberta, Canada. The near-infrared reflectance of vegetation scaled with incoming sunlight was found to be a practical proxy for primary production. The study demonstrates the importance of streamflow and weather-driven soil moisture in influencing ecosystem productivity, and highlights the vulnerability of cottonwood forests to drought and reduced soil moisture.

Summary: Construction of dams in the mid-20th century led to reduced channel dynamism, sediment transport, and riparian tree regeneration on the Missouri River. However, opportunities for forest regeneration exist in areas where sediments are deposited, forming deltaic and upstream backwater regions. This study found that woody vegetation in the delta-backwater area increased from 2012 to 2016, colonizing previously barren areas, highlighting the importance of understanding vegetation dynamics in regulated riverine landscapes for sustainable reservoir management.

Summary: Small impoundments along river corridors have a significant impact on flow alteration, prolonging storm hydrographs, increasing median and baseflows, while decreasing peak streamflow. The density of impoundments exacerbates flow alteration, with large reservoirs having a greater impact on median flows.

Summary: This study investigates the hydrodynamic interaction and wave propagation around prototype scale artificial seagrass (ASG) mats, providing valuable information for seagrass restoration. The results show that the mats can reduce orbital velocities, but the gap between mats can increase velocity instead of attenuating it. Existing hydrodynamic models did not fully capture the induced hydrodynamics but provide accurate insight into expected attenuation under field conditions.

Summary: Our study retrospectively evaluates the perturbances of opencast mining on small rivers, using a standard 'before-after-control-impact' approach. We found that open-pit mining significantly impacts the flow regimes of small-to-medium-size rivers, resulting in degraded functioning of the river ecosystems.

Summary: The lower Brazos River has undergone significant changes due to the construction of multiple impoundments, which has had a major impact on the reproductive and ecological life of native fish species. Some species have disappeared from the region, and the timing and extent of their decline varies. The study found that there have been noticeable changes in flow characteristics, with the upper reach of the study area experiencing the most significant alterations. However, all five locations showed extensive hydrologic alteration. The disappeared species in the lower Brazos River may have been more sensitive to altered flow regimes or dependent on recolonization from upstream populations. Considering nonflow variables is important for understanding biodiversity loss and managing flows to support species that rely on natural flow regimes.
