Bedload transport in pipe channels

Artikel i vetenskaplig tidskrift, 1996

Six series of experimental results on bedload transport in pipe channels with deposited alluvial bed were collected. The observed values were compared with existing formulae for the description of sediment transport in alluvial channels. It was shown that a relationship as simple as those based on one or two parameters is not sufficient for the description of bedload transport in pipe channels and a new relationship for the estimation of this type of transport, based on dimensional analysis, was proposed using 66 observations. The new relationship was verified using the remaining 95 observations and finally modified to cover all 161 observations. With the inclusion of the shape factory B/Y the effectiveness of this relationship was improved.
