Summary: One problematic outcome of soil erosion is sedimentation in stream channels. Reusing dredged sediments in agriculture can be a solution, but farmers are concerned about weed infestation. Research findings confirm the proliferation of weeds after using dredged sediments, and a protocol for assessing the need for weed management intervention is proposed.

Summary: The study found that sediment loads and suspended sediment concentrations showed a progressive change during the six consecutive years of reservoir drawdowns, indicating that most of the stored sediment had been transported out of the reservoir earlier in the drawdowns. The changes in turbidity and dissolved oxygen levels were closely related to the drawdown period.

Summary: Sediment transport as migrating ripples can strongly modulate streambed metabolism under low flow velocity, inhibiting microbial activities, while stationary sediments facilitate an active community of phototrophs. The transition between these two states results in differences in microbial activity and biomass, shaping reach-scale metabolism.

Summary: This study extends the analysis of TRWPs in environmental samples using a density separation and chemical mapping protocol. The identification and characterization of TRWPs are based on physical and elemental surface characteristics, as well as organic surface markers and resistance to heat-induced deformation. The size distribution of TRWPs in environmental samples increases with sample complexity, as determined by the SPA methodologies.

Summary: The restoration of submerged macrophytes in West Lake in China using artificial assisted methods reduced the potential for CH4 production and increased the abundance of dominant methanotrophs in the lake sediment. The average daily CH4 production potential of artificially restored lake areas was significantly lower than that of naturally restored lake areas. Although there was no significant difference in the CH4 oxidation potential between the two restoration methods, the presence of submerged macrophytes significantly increased the abundance of dominant methanotrophs in the sediment.

Summary: The study investigates the effects of periodic and episodic sediment replenishment on channel bed response of a gravel-bed river, finding that sediment supply level and flow discharge exert the strongest control over channel response, while the influence of grain size distribution of replenished material is minor. Sediment replenishment can increase availability of clean gravel patches in rivers, but does not address the general shortage of shallow habitats for grayling fry and juveniles.

Summary: In this study, we conducted experiments in an experimental flume to investigate the transition processes of sediment transport modes along the longitudinal distances from the gradient change point in debris flows. We measured sediment transport concentrations, flow depths, and gravel migration velocities to calculate transition mode indices and found that gravel migration velocities changed most rapidly after the gradient change point, while flow depths changed most slowly. Additionally, it was observed that the length of the transition sections tended to increase with finer debris flow materials and larger supplied flow rates.

Summary: The presence of aquatic plants can significantly change the flow pattern of rivers. Rigid non-submerged plant densities have an influence on solute transport in the hyporheic zone. Laboratory experiments and numerical simulations show that solutes enter the streambed around plants and experience a sharp decrease in concentration initially, followed by a gradual decline. The presence of plants induces pressure gradients and allows solute to transport in the streambed through convection exchange of surface water and pore water.

Summary: This study demonstrates that sediment concentration may influence the magnitude and pattern of vertical density stratification through sampling and measurement under different flow conditions in the lower reach of the Yellow River. The importance lies in the understanding of the vertical density stratification phenomenon in natural river flows, which can improve sediment transport models and provide guidance for ecological environmental management and flood protection measures in rivers.

Summary: This commentary discusses the challenges and opportunities associated with transitioning Water Resources Research to a Gold open access publication model, including a review of open access publishing models, community input, and the path forward for AGU leadership. The decision to switch to open access is framed by a mix of finances and values, with the challenge of defining payment methods and improving affordability, along with increasing the extent of open and accessible science. The next steps for the community involve analyzing the financial feasibility of different cost models and balancing the financial burden of open access with the desire to advance open science further.

Summary: Research indicates a significant increase in burned area and occurrence of forest fires in mountainous regions of the western United States over the past few decades, especially above 2,500 meters in elevation. There is a strong interannual relationship between high-elevation fires and warm season vapor pressure deficit, suggesting the impact of climate warming on high-elevation flammability barrier is crucial.

Summary: Understanding the effects of hydrology on fish populations is crucial for fish conservation. Insufficient understanding of the mechanisms underlying fish responses to changes in flow regimes hinders accurate prediction of fish populations. By studying the mechanisms by which low and high flows influence fish populations and communities, and addressing challenges posed by data limitations and ecological complexity, a more reliable empirical basis for species conservation in changing flow regimes can be established.

Summary: Forest management guidelines are designed to protect water quality from unintended effects of land use changes. Nonperennial streams draining forested areas play a crucial role in connecting forested lands and the aquatic system. Land uses that modify flow regimes in these streams can affect sediment and organic matter transport and distribution, stream temperature dynamics, and biogeochemical processing. Limited research has examined how forest land uses affect ecosystem services and biota in these streams, but recent advances in data collection and research provide opportunities to resolve uncertainties.

Summary: This paper presents a new method, LPMLEn, that uses the frequency domain to estimate vertical flux and thermal diffusivity from streambed temperature time series. It utilizes multiple frequencies and sensors for parameter estimation, handles noise/uncertainty optimally, allows for estimation with both semi-infinite and bounded domain models, and compensates for temperature drifts known as transients. The capabilities of LPMLEn are demonstrated using synthetic and field data, showing the advantages of the bounded domain model over the semi-infinite domain model in parameter estimation.

Summary: Fire has always been a significant part of ecosystems, but human-induced global climate change is now changing fire patterns on Earth's land surface, making it crucial to understand the physical, biological, and chemical processes of fire and its impact on human societies. In 2020, AGU launched a Special Collection across 10 journals, inviting papers on the theme of Fire in the Earth System to promote cutting-edge research in fire-related science. The completed Special Collection consists of over 100 papers. This summary categorizes the published articles into seven themes: paleofire and its correlation with climate; evolution of recent and future fire patterns under ongoing climate change; physical (atmospheric) and chemical processes associated with fire; ecosystem effects, including biogeochemical cycles; physical landscape changes and associated hazards after fire; fire effects on water quality, air quality, and human health; and new methods and technologies applied in fire research.

Summary: Wildland research, management, and policy in western democracies have long relied on concepts of equilibrium, which are now being challenged by factors such as climate change, introduction of exotic species, and anthropogenic land conversion. In the face of increasing system novelty, there is a need for a more inclusive paradigm of collaborative governance and multiple forms of knowledge to adapt to constant change.
