Summary: The study found a strong correlation between air temperature and stream temperature, with the intermittent tributary having a localized moderating effect on stream temperature. Riparian vegetation cover showed little impact on stream temperature along the entire riparian corridor.

Summary: Eastern Australia's climate is characterized by extreme variability and recurring droughts. An analysis of river gauges reveals a significant decline in annual flow since 1992/93, particularly in the far South coast of New South Wales. Changes in land use and river management have contributed to the reduction in flow, coinciding with an increase in woody riparian vegetation. This increase in vegetation is the largest biogeomorphic change experienced by the SE Australian drainage network in centuries.

Summary: Livestock grazing in riparian areas has both positive and negative effects on vegetation. While reserving riparian areas can benefit native vegetation, livestock grazing can reduce exotic vegetation cover at the cost of native vegetation and ground condition. Quantitative monitoring and evaluation of cost-benefit trade-offs are essential for guiding reservation decisions.

Summary: This study investigates the impacts of climate change on flood hazard in the lower Biobio River, Chile. The results indicate that sea level rise, flow increase, and riparian vegetation encroachment can all individually increase flood hazard, with potential compound effects.

Summary: Rigorous assessments of water resources' ecological condition and the impact of human activities on them require quantitative data, showing that artificial disturbances have negative effects on physical habitats. The U.S. Environmental Protection Agency's study found that a certain proportion of rivers and lakes in the country are in poor condition, characterized by anthropogenic disturbances, sediment accumulation, inadequate riparian vegetation cover, and low habitat complexity. The severity of these conditions varies in different ecological regions.

Summary: This study examines the irreversibility of river floodplains to recover their status, which may be explained by the dynamics of riparian water-tolerant plant roots. The developed model provides a quantitative tool for predicting the impact of changing flow regimes on long-term river floodplain dynamics.

Summary: The vertical protrusions of coastal and wetland trees, such as the 'knee roots' of baldcypress trees, create an elevated sediment patch downstream, serving as flood-protected breeding grounds for seedlings. Computational simulations reveal an optimal vertical root spacing dependent on root thickness, and cooperative effects between adjacent root patches. Varying the vertical root spacing allows estimation of a maximal vegetation density with a beneficial geomorphological response.

Summary: In riparian zones of southwest Western Australia, changes in streamflow due to drying climate have different impacts on immature tree frequencies depending on the geographic range of the species. This suggests that riparian species may experience range contractions or expansions. Meanwhile, the river may act as a buffer for upland species.

Summary: With increasing extreme precipitation events due to climate change, there is a growing need to investigate the impacts of extreme flooding on river hydrology and vegetation. This study examined the relationships between hydrology, vegetation, and geomorphology after a record-breaking flood event in South Korea. The results showed widespread devastation of vegetation, with a higher threshold of shear stress required to cause damage to large trees. The presence of vegetation increased the average water depth during floods. The expansion of vegetation in northeast Asia due to infrequent extreme flood events can increase the future flood risk to surrounding areas.

Summary: Rapid urbanization has increased the demand for sand in the construction industry, leading to the negative impact of sand mining on the water quality and riparian vegetation. The study used GIS and remote sensing techniques to assess the changes in riparian land cover from 1990 to 2021. The results showed an increase in sand mining area and a decrease in river bed area and woodland cover, as well as a lower woody plant diversity in the mined area compared to the unmined area.

Summary: The study revealed that forested riparian buffers are associated with greater shading, increased gravel content in stream substrates, and faster flow velocities. It also found that riparian vegetation types influence the structural and functional composition of stream invertebrate communities, with implications for stream health and cross-ecosystem connectivity.

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: Climate change projections indicate that snowpack levels and winter precipitation will decrease in the western United States. This will lead to increased seasonal variation in flow in mountain streams, posing significant conservation risks for fish species. Research suggests that the shift from perennial to intermittent flow will cause significant declines in abundance for some species.

Summary: The study highlights the impacts of traditional farming practices on exposed riverbanks and water quality, mainly attributed to traditional meadow management, abandoned mill weirs, and occasional timber harvesting. While certain indicators differed between exposed and reference sites, the majority of riparian taxa benefited from larger forested areas.

Summary: River floodplains have been heavily impacted by dam construction and flow regulation along the Missouri River, resulting in the invasion of non-native species like redcedar. However, a major flood in 2011 significantly reduced the distribution of redcedar, particularly in well-drained, non-flooded areas. The study highlights the importance of large floods in constraining redcedar spread in floodplain habitats, as well as the significant impact of soil drainage on redcedar survival and colonization.
