SEDIMENT TRANSPORT ANALYSIS AND MODELLING USING WINXSPRO: “A CASE STUDY OF THE SEDIMENT TRANSPORT APPARATUS”

Abstract

The focus of the research paper was to study the dynamics of sediment transport in river flow channel using the sediment transport apparatus. Field measurement derived from sediment transport apparatus and computer models were used to estimate bank full discharge and bed load transport along the channel. Cross-sectional profiles such as longitudinal distance along the channel and the water/bed surface elevation were measured to simulate real river scenario. Linear regression statistical model was then employed to generate the linear relationship between horizontal distance along the channel and the corresponding water/bed surface elevation. The final equation was then used to extrapolate sufficient data that was used for the modeling. These data were then incorporated into software (WinXSPRO) that aids in the characterization and computation of stage, discharge, velocity, and shear stress in addition to the hydraulic depth, fraud number and other parameters used in assessing a typical stream conditions. The relationship between the computed hydraulic parameters was thereafter studied using the parameter plot option of the software.
