Description
Sediment transport, especially bed load, is of great importance in the occurrence of morphological changes in stream channels and has been the subject of systematic research by researchers and engineers over the past hundred years (Gomez 1991). Numerous methodologies for calculating bed load have been proposed. However, none of these have been rigorously evaluated using a temporal data series (Gomez 1991; Basile 2000).
In addition, the great variability of the results when calculating sediment volume using the same data but different equations is evident. This complicates the decision-making process for practitioners when choosing the equations to model fluvial processes. The questions that arise are which equation to use and how the results represent reality
This research, supported by ICE, SENARA, and Queen's University, aims to evaluate the de Meyer-Peter and Müller, Bagnold, Engelund Hansen, Van Rijn, and Yalin equations in a section (to be defined) of the confluence of the Reventazon and Parismina rivers. The methodology involves the aid of a computational model and a physical model, as well as field data. The outcome of the research will be a detailed report, including an extensive analysis of the results, to be offered to practitioners as a guide when calculating or modeling bed-load sediment transport. Furthermore, the results of the research will contribute to the systematization of information and research on bed-load sediment transport and will contribute to the relatively few published studies on the topic
