Abstract: Extensive research efforts in the last few decades have only partially elucidated the complexities of suspended-sediment transport. Lacking an adequate formulation and quantification of the interaction between suspended particles and the carrier liquid, it is common practice to combine sediment mechanics theory and empiricism to obtain predictive formulations. Flume data for suspended sediment transport, however, is incomplete and often inconsistent with respect to insights into sediment effects on water flow. Improvement of the data quality/reliability for future experiments requires thorough evaluation of the current experimental investigative approaches and identification of new research paths. The present paper reveals several limitations of the existing flume investigations of suspended-sediment transport. Considered next are the benefits resulting from the adoption of a two-phase flow approach in the investigation of this flow process. Emphasis is placed on illustrating the potential of the new generation of non-intrusive measurement instruments for increasing the reliability of the experimental results.
