Flood Suspended Sediment Transport: Combined Modelling from Dilute to Hyper-Concentrated Flow

During flooding, the suspended sediment transport usually experiences a wide-range of dilute to hyper-concentrated depending on local flow and ground conditions. This paper assesses distribution for variety flows. Due differences between flows, linear-power coupled model is proposed integrate these considerations. A parameterised method combining size, Rouse number, mean concentration, depth parameters has been used modelling profile. The accuracy verified against reported laboratory measurements comparison with other published analytical methods. shown effectively compute concentration profile wide range conditions from Detailed comparisons reveal that calculates good correspondence measured data results literature. For profile, clear division lower (bed-load) upper layer (suspended-load) can be observed in data. Using model, transitional point this calculated precisely.
