“…Hence the question arises: Does the relation of MPM in fact fit the data used in its derivation? Answering this is of significance not only because the MPM bedload transport predictor is commonly used for comparative purposes in basic research (see e.g., Abdel-Fattah et al 2004;Barry et al 2004;Bettess and Frangipane 2003;Bolla Pittaluga et al 2003;Bravo-Espinosa et al 2003;Defina 2003;Gaudio and Marion 2003;Knappen and Hulscher 2003;Martin 2003;Mikoš et al 2003;Nielsen and Callaghan 2003;Ota and Nalluri 2003;Singh et al 2004;Yang 2005), but also because it is frequently used in engineering applications (it is one of the relationships available in HEC-6, a computer software used for sediment transport calculations that is very popular in the USA).…”

ABSTRACT:The pioneering predictor of fluvial bedload transport rate proposed by Meyer-Peter and Müller in 1948 is still extensively used in basic research and engineering applications. A review of the basis for its formulation reveals, however, that an unnecessary bed roughness correction was applied to cases of plane-bed morphodynamic equilibrium. Its inclusion followed a flow resistance parameterization in terms of the Nikuradse roughness height, which has been shown (well after the publication of their work) to be inappropriate for the characterization of

“…This concept is defined as "limit deposition" or "no deposition". However, designing sewers so as to have velocities that do not maintain sediment (solids) deposition can impose severe conditions on sewer design, as this would require large slopes and high flow velocities (Ota & Nalluri 2003). On the other hand, a number of studies show that designing sewers with limited loose bed deposits can lead to more economical solutions.…”

This paper investigates in-sewer sediment deposit behaviour and its influence on the hydraulic performance of sewer pipes. This evaluation is based on experimental results regarding the mobility of non-cohesive and partly cohesive deposits in a partially full circular pipe. The focus of these tests is on the development of bed forms and friction characteristics. In particular, it is investigated to what extent the bed forms from the non-cohesive and (partly) cohesive sediments affect a sewer's discharge capacity. Based on the laboratory study results and on the existing criteria for sewer design, a generic assessment of a sewer's hydraulic performance is made. The relative discharge factor for a pipe with sediment deposit is analysed in terms of the thickness and roughness of the deposit.

“…The transport rates of sediment mixtures have been found to be higher than those for uniform materials with the same d 50 . For instance, according to Ota & Nalluri (2003) the sediment transport may increase by some 50% when the geometric standard deviation of the ( Therefore, it is more appropriate to make an intercomparison of these formulas and to apply them to the conditions similar to which they are derived. Here, data from a concrete laboratory pipe (diameter 390 mm) and a Figure 3 presents the selected methods and shows that they provide sediment transport predictions ranging in one order of magnitude.…”

The reliability of sediment transport predictions in sewers: influence of hydraulic and morphological uncertainties

The paper is focussed on the concept of defining the "predictability" of sediment transport. Engineers are faced with a number of sediment transport formulas derived from different tests and described as suitable for application in sewers. Bed and suspended load formulas vary in form and performance, generally depending on the data sets that were used to calibrated them. As different sediment types have been tested no single, generally valid formula has been established so far. Formulas are distributed in the scientific literature and are often reported without the information necessary to define their range of potential applicability. Therefore, this paper along with analysing the formulas available, will also comment on the assumptions used in their development as well as the reliability of their underlying data to aid engineers in the selection of the most appropriate sediment transport formulae to correspond with the environment in which they are working.
