Summary: The contamination of oceans, freshwaters, and soils by microplastics has become a major challenge in the Anthropocene. This study investigates the spatial distribution of microplastic particles in floodplain soils and advances our understanding of their deposition and relocation at the aquatic-terrestrial interface.

Summary: Hydrologic connectivity plays a critical role in the lateral exchange between rivers and floodplains. This study investigates the impact of heavy rainfall on floodplain hydrodynamics, using data collected during Tropical Storm Imelda in the Trinity River floodplain. The study reveals that rainfall initiates lateral exchange before river discharge reaches flood levels, and rainwater generally remains in the floodplain for a longer time than river water after the rain stops. The study emphasizes the complexity of floodplain hydrodynamics under heavy rainfall conditions and its implications for sediment deposition and nutrient transport.

Summary: Floodplain deposition provides important historical information about river systems, and the 137Cs tracer technique is commonly used to estimate deposition rates. This study investigated floodplain sedimentation in the Laolai River basin, a tributary of the Songhua River, using cross-sectional sediment core sampling. The results showed internal heterogeneity in sedimentation and the influence of sampling positions on the analysis results. Sedimentation patterns were mainly influenced by topography, reservoir construction, and land use. Consideration of river bank erosion and variations in 137Cs content and particle size distribution is important when using sedimentation and floodplain distribution to determine flooding occurrence.

Summary: This paper addresses the impact of agricultural expansion on hydrological patterns in the Cambodian Mekong floodplains. Using field and remote sensing data, the study found changes in water level, sediment concentration, and sediment budget due to agricultural expansion. The study suggests that deforestation and land surface elevation changes caused by agricultural activities are driving factors behind the observed hydrological patterns in the floodplain.

Summary: The study evaluated the nursery function of restored floodplain channels for rheophilic fish in the lower river Rhine by analyzing 30 years of monitoring data from 12 restoration projects. It found that the nursery area suitability was higher in two-sided connected channels, with rheophilic fish abundance reaching optimal conditions at 13 to 14 years post-restoration. However, rheophilic species richness showed a decreasing trend with channel age, indicating aging channels became less suitable as nursery areas for most rheophilic fish species.

Summary: This study reconstructed the long-term succession of phytoplankton community in Poyang Lake and revealed the potential mechanisms of lacustrine ecosystem response to climate-nutrition-hydrology factors. Results showed rapid growth of algal community in Poyang Lake, with increases in diatoms and cryptophytes, and decrease in green algae. The point of change in algal community succession occurred after 1965, representing a delayed response compared to lakes worldwide, due to the unique hydrological fluctuations and anthropogenic disturbances.

Summary: This study investigated the sediment and nutrient retention in floodplain vegetation along the River Mulde in Germany. It found that sedimentation on vegetation surfaces was mainly influenced by plant biomass and height variation, while sedimentation underneath vegetation was not driven by vegetation characteristics. Carbon, nitrogen, and phosphorus content in sediment increased with the total sediment amount, and also increased with hydrological distance on vegetation.

Summary: The fate of organic carbon in floodplain sediments plays a crucial role in understanding carbon flux in human-impacted river networks. This study investigates deposition and decomposition rates in two geomorphic zones of a river in SW England, finding faster rates in the active channel belt compared to the floodplain. The study suggests that maximizing active floodplain areas through restoration projects could enhance soil carbon storage.

Summary: This study aims to investigate the multi-metal distribution patterns and controlling factors of 38 metals in the Sacramento River floodplain. The study identified 484 significant correlations between metal distributions and found 13 individual metal patterns and three multi-metal patterns. The distance to specific streams and local soil properties were identified as the most important controlling factors.

Summary: Our study aimed to understand the impact of channel correction on the evolution of hydraulic structures in the Rhone River. Through geohistorical analysis and GIS modeling, we identified patterns of change in dike fields and their relation to topography and sedimentation. The study also found that the degradation of dike fields in the 1970s-2000s was primarily caused by a drop in water level. Understanding the evolution of these ecotones can inform the restoration and management of river environments.

Summary: The sedimentation rate in tidal marshes increases with water depth, and elevation is negatively correlated with accretion rate while positively correlated with total organic carbon content. Spatial patterns of cross-sectional morphology in wetlands conform to typical forms in estuarine areas, but differ in riverine reaches. Channel perimeter and surface area exhibit high variability between estuarine and riverine reaches.

Summary: The study investigated changes in forest extent in the corridors of four rivers of the Polish Carpathians over the last 130 years and their relation to changes in river geometry. It found that all the analyzed rivers narrowed significantly over the study period, leading to an increase in the proportion of floodplains in the area of the river corridors, while former wide channels became places of forest development.

Summary: Floodplain wetlands are important for riverine food webs, but their contribution depends on landscape connectivity during flood pulses. Changes in floodplain inundation extent and duration can impact connectivity and the magnitude of the food web subsidy. This study used graph theory and new metrics to explore connectivity changes and found that water resource development can reduce algal production on floodplains by up to 26%.

Summary: This study used a hydrological model and the Hydraulic Mixing-Cell method to examine the long-term impact of climate change on water signatures and their spatial distribution in the Biebrza River Catchment in Poland. The results showed that water sources were relatively stable in the past, but future impacts varied depending on the scenario. The study also highlighted the need for protective and preservation strategies of floodplain wetlands.

Summary: The lateral dimension of a river system is crucial for the sustainable management of river-floodplains. This study proposes a hydro-bio-geomorphological framework to assess the lateral dimension and introduces the concept of river space. By combining hydrological and bio-geomorphological approaches, the study determines the river space range at hydrometeorological sites in the Ganga river plain.
