Predicting the sediment transport capacity from flow condition and particle size in the presence of vegetation cover

Hongli Mu et al.

Summary: This study investigated the impact of vegetation cover on the relationship between hydraulic variables and sediment transport capacity, and derived an equation for predicting sediment transport capacity in the presence of vegetation cover. The results showed that unit stream power was the strongest predictor of sediment transport capacity, followed by stream power, flow velocity, and shear stress. Vegetation cover had no direct effect on the relationship when unit stream power or stream power was used as a predictor, but became significant when shear stress was used. A new equation involving slope gradient, flow velocity, and median sediment diameter was shown to be a superior predictor with an efficiency coefficient of 0.92. The product of slope and flow velocity, unit stream power, was found to effectively capture the effect of vegetation cover and surface roughness on sediment transport capacity.

Effects of different types of undecomposed surface litter on the sediment transport capacity

Lin Ding et al.

Summary: This study examined the effects of different types of plant litter on hydraulic variables and sediment transport capacity, as well as the quantitative relationships among them. The results showed that the morphology of individual litter leaves can impact sediment transport capacity, while the relationships between sediment transport capacity and hydraulic variables were not influenced by litter morphology. The findings can be used to develop a simple algorithm for predicting sediment transport capacity on litter-covered surfaces.

Hydraulic properties affected by litter and stem cover under overland flow

Lin Ding et al.

Summary: This study compared the effects of stem and litter cover on sediment transport capacity, revealing that stem cover contributes more to increasing flow resistance and reducing sediment transport capacity compared to litter cover. New equations were developed to calculate Manning's n and flow velocity under the influence of litter cover, with high accuracy.
