Unified classical formula for non-cohesive total-load sediment transport in marine coastal zones.

This paper proposes the concept of a significant transport rate, in coastal environments that contains different spatial and temporal scales and multiple interacting forces (e.g., waves, tides, wave-current, and wind density currents) as well as, the complex physical processes of total-load sediment which is not easy to calculate for practical needs due to restricted range of applicability. The present study develops a unified classical formula for non-cohesive total-load sediment transport in marine coastal zones by using dimensional analysis and self-similarity concepts where a set of independent variables considered. A dataset of total-load collected at both field observation stations and from the laboratory flume conditions and the six well-known relevant formulas were used to evaluate the predictive capability of the proposed formula. Since the results show that, the new formula is in good agreement with both field and flume data sets measures, the authors are suggesting the use of it for the sediment-carrying capacity predictions of total-load sediment transport in marine coastal zones.
