The Rouse formula and its variants have been widely used to describe the vertical distribution of sediment concentration in sediment-laden flows equilibrium. Han’s extends non-equilibrium regimes, where diffusive flux is still assumed be Fickian. turbulent flow suspension regimes downstream a mega-reservoir, e.g., Three Gorges Reservoir, usually exhibit fractal unsaturated properties, respectiv...

abstract in this study, the effect of suspended load transport on the characteristics of submerged hydraulic jump (shj) in a rectangular channel was investigated experimentally. sediment concentration and jet froude numbers in the range of 0.424%-16.15% and 1.93-4.96, respectively, were considered. tow grain size 0.15 and 0.03 mm were used in the experiments. characteristics of submerged hydrau...

[1] Understanding and quantifying the long-term suspended sediment discharge of drainage basins is a key goal of geomorphology, with important implications for the study of water quality, agricultural sustainability, and the evolution of landscapes and sedimentary basins over geologic timescales. Previous studies have highlighted the importance of relief/slope, precipitation, temperature, veget...

The alluvial flood plains of lowland Britain contain thick sequences of fine-grained sediment that result from the deposition of suspended sediment during flood events. These environments constitute important storage zones for a wide range of sediment-associated nutrients and con­ taminants and many of the geochemical properties of the deposited sediment are strongly related to particle size. R...

This study demonstrates the use of suspended-sediment concentration (SSC) data collected at Mallard Island as a means of determining suspended-sediment load entering San Francisco Bay from the Sacramento and San Joaquin River watersheds. Optical backscatter (OBS) data were collected every 15 min during water years (WYs) 1995–2003 and converted to SSC. Daily fluvial advective sediment load was e...

Analysis of suspended sediment transport data for rivers in Yunnan and Tibet shows that monsoon fl ows control effective discharge. We calculate effective discharge, defi ned as the discharge that transports the most sediment, for 44 stations for which there is at least one complete year of daily suspended sediment concentration and mean daily discharge data, and fi nd that the effective discha...

This study investigated the prediction of suspended sediment load in a gauging station in the USA by neuro-fuzzy, conjunction of wavelet analysis and neuro-fuzzy as well as conventional sediment rating curve models. In the proposed wavelet analysis and neuro-fuzzy model, observed time series of river discharge and suspended sediment load were decomposed at different scales by wavelet analysis. ...

The Himalayan Rivers due to their steep bed and side slopes, narrow width and fragile geology of the region carry huge amount of sediment with them. Many runof-river hydro power projects are coming up on these rivers and suspended sediment enters into the power intake of these projects. Desilting chambers are provided to remove / minimize the suspended sediment from water conductor system. The ...

Recent years have seen a growing awareness of the wider environmental significance of the suspended sediment loads transported by rivers and streams. This includes the importance of fine sediment in the transport of nutrients and contaminants, including phosphorus (P). Sediment source exerts a key control on the physical and geochemical properties of suspended sediment, including its P content,...
