“…Beyond the scale of an individual plant or plant patch, groups of plant patches typically display spatial patterns that optimize flow velocity, turbulence and drag on individual patches (Cornacchia et al, 2018). Flume experiments have investigated the hydraulic and sedimentation effects of these plant traits in the context of riparian (e.g., Manners et al, 2015; Stone et al, 2011; Västilä & Järvelä, 2014; Zhu & Tsubaki, 2022) and aquatic species (e.g., Miler et al, 2012; Nepf, 2012; Zhu et al, 2012).

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

“…The greater the width and width-to-depth ratio (w/d) of a riparian wetland, the lower the gradient required to take the water load. The flow is slowest near wetland beds, shallow banks, and ditches, and fastest by the centre of the water [30]. As the width or hydraulic radius of a channel increases, the slope does not have to be as great to transport the same sediment load.…”

Although geodesign techniques have been studied and developed worldwide, there is still a lack of in-depth application of geodesign workflows for redesigning urban river wetlands with characteristics of ecologically engineered landscaping (EEL). The study mainly aims at putting forward a proper approach in the methodological foundation for EEL practices in river wetlands. A typical EEL-oriented project of river restoration in Hangzhou, China, was conducted in this study. Based on in-situ geodata and tools within QGIS, individual geological factors analysis, with the hierarchical analysis method (AHP) and ecological vulnerability evaluation (EVE), was conducted by experts’ voting and the weighted linear combination (WLC) method. Analysis of hydrological-related factors proceeded. This GIS-based analysis with expert knowledge provided comprehensive redesign solutions for the redesign project, i.e., restoration of the riverbed, spatial restoration in the horizontal and vertical dimensions, and integration with the multifunctional design. Detailed three-dimensional models for design practices were developed to present redesigned topology and space accordingly. Terrain, inundation, and visibility analysis proceeded with parametric mapping programs within Grasshopper to check the feasibility. The adapted geodesign-based workflow in the study also applies to the site analysis, sustainable assessment and landscape planning for urban wetlands EEL projects.

Submerged aquatic vegetation (SAV) changes the turbulent structure of rivers, wetlands, estuaries, and lakes. However, few studies have focused on the influence of SAV on hydrodynamic characteristics under wind-induced flow. Therefore, laboratory experiments were conducted to study the effects of SAV on the flow structure and turbulence characteristics under wind-induced flow and spectral based decomposition method were used to separate turbulence and wave velocity. Result shows that SAV reduced local velocity within canopy and elevates the location of the zero-velocity point. The canopy drag caused by SAV increase the decay rate of turbulent Reynolds stress along depth while hardly influence wave Reynolds stress. Canopy drag depress the turbulent RMS velocity and wave orbital velocity, the suppression of turbulence by SAV is greater compared to the impact on wind-wave. The presence of SAV leads to the decrease in TKE production and dissipation rate within canopy. The canopy drag more effectively diminishes TKE production than it does the dissipation. Research on local isotropy of SAV in wind-induced flows shows that the presence of SAV promotes a gradual transition from local anisotropy to local isotropy in turbulence within canopy. And quadrant analysis reveals that the presence of SAV reduced the probabilities and the contribution to turbulent momentum of ejection and sweep.
