one-dimensional numerical model of cohesive sediment transport in open channel flow
cohesive sediment transport remains a complicated subject that hydraulic engineers are frequently faced with in water-related engineering problems. this is primarily affected by the macroscopic aspects of water-sediment system characteristics. in this paper a 1-d mathematical model was developed to be employed in predicting the cohesive sediment transport under simultaneous conditions of erosio...
متن کاملModeling Near-Surface Suspended Sediment Concentration in the English Channel
The present study investigates the performances of the three-dimensional multicomponent hydro-sedimentary model ROMS (Regional Ocean Modeling System) to predict near-surface suspended sediment concentrations (SSC) in the English Channel (western Europe). Predictions are assessed against satellite-retrieved observations from raw MODIS and MERIS images for the year 2008 characterized by the highe...
متن کاملTitle: Flow-vegetation-sediment interaction in a cohesive compound channel
3 The purpose of this study was to quantify how vegetation influences the flow and sediment processes 4 relevant for the design and management of environmental compound channels. Therefore, we conducted a 5 two-year field investigation in a cohesive two-stage channel, focusing on the flow resistance and net 6 deposition in five sub-reaches with different floodplain vegetation conditions. In the...
متن کاملSediment Transport in Unsteady Flow Conditions
Sediment transport under unsteady flow condition is studied experimentally. In the first step, sediment transport under different steady flow conditions was measured and an empirical equation was derived for its calculation. In the next step, two continuous and three stepwise hydrographs were generated in the flume, and their sediment transport rate was measured. The continuous hydrographs were...
متن کاملDirect Numerical Simulation of Sediment Transport in Turbulent Open Channel Flow
Direct numerical simulations of interface-resolved sediment transport in horizontal open-channel flow are currently being performed on the XC-4000. The channel bottom boundary is roughened with a fixed layer of spheres and about 9000 particles are allowed to move within the computational domain. The density ratio of the solid and fluid phase is 1.7 and the bulk Reynolds number of the flow is 28...
