... ABSTRACT Taking the Chongming Dongtan Wetland in the Yangtze River Estuary as study region, a three-dimensional hydrodynamic model was established considering the temporal and spatial distributions of vegetation features based on Delft3D in this paper to analyze the influence of vegetation...

... attention (Borsje et al., 2011; Temmerman et al., 2013; Scarano, 2017). Employing coastal vegetation to maintain a bioshield as the first buffer line to reduce coastal risks has been admitted as a promising coastal protection solution (Mazda, 1997; Tang et al., 2015). The importance of ecosystem-based...

... ABSTRACT Vegetation has great influence on flow structure and sediment transport, which will further affect the pollution diffusion and the eco-system. Laboratory experiments were carried out in this paper to investigate the effects of submerged rigid vegetation on sediment transport under...

... ABSTRACT Dynamic characteristics and wave attenuation mechanism of flexible vegetation is fundamental to ocean engineering and nature-based coastal defense solutions. Based on simulation results by the flexible vegetation dynamic model, relative water depth, wave height, wave period...

... Abstract A series of experiments were carried out in a wave flume to study wave attenuation by a sandbar with different emerged vegetation densities. The results show that: Significant wave height can be reduced by 11.76% due to sandbar only. The high density emergent vegetation on the sandbar...

... of wetland ecological restoration is to plant tamarix, mangrove, reed or other plants. These vegetation can effectively restore the coastal wetland ecosystem, and play an important role in maintaining coastal biodiversity, purifying water quality, reducing soil salinity and other aspects. Meanwhile...

... protection. The SWAN (Simulating Waves Nearshore) model has achieved good simulating results on vegetation-induced wave dissipation in the condition of pure waves, while the effects of the tidal currents are ignored. A revised formula based on Hu Suzuki, Zitman, Uittewaal and Stive (2014) formulation...

... on the intertidal flats has been revealed to retard flows, attenuate hydrodynamic energy and subsequently stabilize coastal zones (Shi et al., 1995; Fonseca, 1996; Bouma et al., 2007; Neumeier, 2007; Horstman et al., 2013; Chen et al., 2016). Numerous studies have shown that vegetation canopies on the intertidal...

.... The previous research studies dealing with mangroves forests were reported as follow; (Mazda et al.,1997), sea surface elevation and currents were observed and estimated the wave height reduction up to 20% per 100m of vegetation were calculated from the observations along the observational transect...

... Abstract A physical model experiment based on a 1:10 model scale is performed to test the wave absorbing ability of vegetation on a revetment. In this test, the vegetation arrangement, trees rows, submerged depth and different planting locations are considered to analyze the absorbing effect...

... ABSTRACT Based on existing wave dissipation model by vegetation, a kind of forced vibration with damping model is used to take care of the vegetation swaying in the water waves with different wave parameters. By introducing the factor D as the concession to the wave force, the drag coefficient...

... ABSTRACT It is well known that sediment movement is affected by aquatic vegetation under flow and wave conditions. However this impact is not fully understood yet. The aim of this study is to determine the effect of emergent vegetation on suspended sediment flux under wave conditions...

... ABSTRACT: Joint numerical and experimental studies were carried out to examine the potential mitigating capabilities of beach vegetations on runup and inundation caused by long waves such as tsunamis and storm surges. Three tropical species of vegetation, namely, Akiaki (a salt tolerant grass...

... ABSTRACT: In this paper the effects of layered coastal vegetation on long wave (solitary wave) propagation were investigated experimentally in a long wave flume. This layering vegetation is represented by an open gap in a patch of vegetation that lies perpendicular to the flow direction...

INTRODUCTION For large relatively homogeneous vegetated areas (i.e., Great Plains of North America, Canadian Northwest Territories) mesoscale climate simulations have been suggested to improve...

... which depends on the flow velocity. Sediment concentration at the reference level is evaluated by the author's model(1986), which is a modification of the Kalkanis" model(1965). Near the artificial seaweed, flow is distorted shoreward at the boundary of vegetation. The organized vortex generated...
