Summary: This study assessed the influence of river corridor morphology and forest stand density on the depositional patterns of large wood (LW) and coarse particulate organic matter (CPOM) on a floodplain after an extreme flood in West Creek, Colorado. The results showed the importance of extreme floods for LW deposition and highlighted the role of standing trees as trapping locations for CPOM. The study suggests that forested floodplains play a crucial role in providing habitat and nutrients to floodplain ecosystems, while also influencing geomorphic processes.

Summary: Lowering flood embankments on the River Dee in Scotland improved hydrogeomorphic connectivity between the river channel and floodplain, resulting in channel aggradation, bank erosion, and gravel deposition. Monitoring showed that this targeted action increased floodplain water levels and decreased the threshold river discharge for backwater connection, enhancing future catchment resilience. Such interventions may benefit water storage and biogeochemical processing in the long term.

Summary: This study investigates the stage-area hysteretic relationship in large heterogeneous lake-floodplain systems using the Poyang Lake as an example. By utilizing multi-source remote sensing data and observed water levels, the Enhanced Spatial and Temporal Adaptive Reflection Fusion Model (ESTARFM) is adopted. The results show significant inconsistency in inundation dynamics between the main lake and seasonal floodplain lakes. Furthermore, it is found that seasonal lakes in floodplain settings have a crucial impact on the hysteresis of upstream and downstream stations. This study provides valuable insights into the complexity of hydrological behavior in large heterogeneous lake-floodplain systems, which is important for lake water resources and ecological management.

Summary: Floodplains of large rivers are utilized for various purposes, but the occurrence of frequent floods has led to the consideration of managing these floodplains for ecosystem services. A study conducted on the Lower Missouri River in the USA found that the inundation metrics and their spatial distribution are influenced by geomorphic adjustments and climate change. The capacity of floodplain connectivity to influence ecosystem services varies significantly along the river and may be affected by climate change.

Summary: This paper presents the geomorphic classification and bathymetry of 12 major floodplains along a 900 km reach of the middle-lower Amazon River, based on inundation frequency derived from Landsat data. The IF-depth model is applied to estimate bathymetry, and the model's applicability is justified by a hydrogeomorphic classification. Field survey data validate the bathymetry, showing a strong relationship between estimated and measured depth with an error of around 1 m. This study provides a complete bathymetry map for the middle-lower Amazon River, which can be used to evaluate the floodplains' role in influencing biodiversity, sedimentation, flood control, and biogeochemical cycling.

Summary: This study examines the resilience of floodplain vegetation communities over medium and long term times scales by analyzing the spatial organization of different vegetation communities. The results show substantial changes in the extent and spatial configuration of vegetation communities over a 40-year period, with many transitions between flood dependent and non-flood dependent vegetation communities. However, there is a trend towards transitions to cleared vegetation, indicating a loss of system resilience in some areas of the floodplain.

Summary: The revised Murray-Darling Basin Plan is set to be implemented in 2026, and considering its complexity and the issues involved, it is important to identify the main drivers of change, anticipate potential changes, and prepare stakeholders for their involvement in the planning process. In this regard, we focus on factors such as water availability, policy changes, and water governance by public agencies, aiming to stimulate stakeholders to think and prepare for contingencies that may impact their interests. Recognizing rivers as complex social-ecological systems, we highlight how structural circumstances and forms of social capital can influence individuals and communities in maximizing their natural assets and building resilience against unfavorable contingencies. Finally, we provide suggestions on how stakeholders can strengthen their ability to respond to opportunities and threats. While the future is uncertain and planning processes are flawed, stakeholders' understanding and response to current challenges will significantly affect their resilience.

Summary: This study examines the spatial organization and strength of geomorphic boundaries within the river network of 10 drainage basins in the Kimberley region of NW Australia. The research finds that the river network in the Kimberley region is naturally highly fragmented, and tributary confluences are not the dominant control on discontinuities in the river network. The strength and spatial organization of geomorphic boundaries play a crucial role in the fragmentation of the river network.

Summary: Restoration activities aim to reverse environmental degradation and return a system back to its original state, but this may not be realistic in the Anthropocene where human disturbances dominate ecosystems. Limited empirical data are available to evaluate river recovery after restoration activities, and current response models assume rivers return to pre-disturbance conditions. A framework for river recovery in the Anthropocene is proposed, incorporating resilience thinking, landscape ecology, and river science.

Summary: Small glaciers in temperate mountain regions have experienced significant reduction and unprecedented melt rates in recent years. Some glaciers have transitioned from clean ice to debris-covered or even rock glaciers. This study examines the surface elevation change of the Popera Alto glacier in the Sesto Dolomites using LiDAR and Structure from Motion surveys, and analyzes its evolution in terms of surface cover and geomorphic processes. The glacier has lost an average of 0.35 m water equivalent per year over the past 16 years, with active modification of its surface cover by geomorphic processes. The role of debris and local topography feedback has allowed the resilience of the glacier, leading to a marked difference between the current environmental equilibrium line altitude (envELA) and the effective ELA (effELA) of the glacier.

Summary: The study investigates the relationship between glacial dynamics and lake sedimentation during the mid-Holocene climate variability in the Southern Zanskar ranges. It utilizes geomorphological disposition, elemental geochemistry, and optical chronology of relict lake sediment to reconstruct the pattern of minor glacier responses to climate variability. The results indicate six centennial to millennial-scale climatic phases, with warmer phases represented by decreased mineralogical fine grain flux and increased coarse grain flux. The study highlights the potential of relict lake sediment and para/peri-glacial landforms in understanding glacial dynamics and climate change during the Holocene.
