Abstract In this article, we track the evolution of fluvial biogeomorphology from middle 20th century to present. We consider emergence as an interdisciplinary research area that integrates knowledge drawn primarily geomorphology and plant ecology, but with inputs hydrology landscape ecology. start by assembling evidence for field a keyword search Web Science detailed analysis papers published in two scientific journals: journal—Earth Surface Processes Landforms; multidisciplinary river science journal—River Research Applications. Based on evidence, identify three distinct time periods development biogeomorphology: ‘early years’ before 1990; transitional decade 1990s; period rapid expansion diversification themes, methods investigation scales since 2000. Because literature is vast, can only summarize developments each these periods, refer recent in‐depth reviews conceptual perspectives relevant topics. Thus, rather than full deep review, present annotated bibliographic overview biogeomorphology, whereby text describes broad trends supported tables citations deliver greater detail. end brief consideration likely future developments.

Abstract Wood accumulations influence geomorphic, hydraulic, and ecologic functions within a river corridor, but characterizing these presents challenges across range of field remote sensing methodologies. We evaluate the ability handheld lidar scanners, specifically lidar‐scanning capabilities fourth‐generation iPad Pro, to collect three‐dimensional wood accumulation data, which can be used inform measurements volume, porosity, complexity, roughness. discuss potential limitations this novel methodology for research management. found that cost‐effective input data‐processing workflows dimensions cannot as easily replicate including (1) user‐friendly means data collection visualization; (2) accurate comparisons volume over time; (3) integration into measure porosity parameters; (4) use in informing hydraulic morphodynamic models. Consideration study area constraints intended scans are prerequisites using an effective tool. identified some specific scanners wood‐rich corridors, perform poorly when is under water or surrounded by dense vegetation; require physical access areas interest at distances less than 5 m; need manually georeferenced; manual any dimensional still have associated user time error.

Abstract Continuous, high‐resolution data for characterizing freshwater habitat conditions can support successful management of endangered salmonids. Uncrewed aircraft systems (UAS) make acquiring such fine‐scale along river channels more feasible, but workflows quantifying reach‐scale salmon habitats are lacking. We evaluated the potential UAS‐based mapping hydraulic using spectrally based depth retrieval and particle image velocimetry (PIV) by comparing these methods to a well‐established flow modeling approach. Our results indicated that estimates water depth, depth‐averaged velocity, direction derived via remote sensing techniques were comparable in good agreement with field measurements. Predictions spring‐run Chinook ( Oncorhynchus tshawytscha ) juvenile rearing produced from PIV model output similar, small errors relative direct observations. Estimates heterogeneity on kinetic energy gradients generally consistent between modeling, measurements larger. sensitive velocity index used convert surface velocities velocities. Sun glint precluded analysis margins some images large degree overlap frames was thus required obtain continuous coverage reach. Similarly, shadows cast riparian vegetation caused gaps bathymetric maps. Despite limitations, our suggest sites sufficient texture, provide detailed information at reach scale, accuracies traditional multidimensional modeling.

Abstract Logjams may form at natural obstructions and are also used as nature‐based solutions for river restoration flood management. Previous research has described backwater rise due to logjams that span the full channel cross‐section with a gap between lower edge of logjam bed. fill depth, but not its width, leaving lateral bank, common formations focus this study. The flow distribution gap, rise, wake turbulence key factors in determining ecologic risk impact logjam. Specifically, relative channel‐spanning logjam, introduction can reduce increase potential trapping particles, such nutrients or microplastics, within region, promote erosion gap. choice widths be maximize habitat diversity rivers, while reducing risk. We present experimental results demonstrating predicted by assuming equal resistance through sections. Further, we show determined from discharge using momentum balance developed logjams. Finally, generated jam was observed directly downstream and, densities considered, increased density.
