SedTRAILS - Sediment transport visualization and langrarian simulator : A novel method to visualize and analyse sediment transport pathways

This report forms part of the Dutch knowledge program KPP – BenO Kust and presents the SedTRAILS tool. SedTRAILS is a novel method that visualizes sediment transport pathways based on the sediment transports computed with Delft3D. SedTRAILS is not a sediment tracer, but a post processing routine that uses high-resolution sediment transport vectors from Delft3D to compute sediment trajectories or pathways. It was demonstrated through two case-studies for the Columbia River and for the Western Scheldt that sediment trajectories can be computed efficiently and robustly. Analysis of the sediment pathways provides a valuable new additional method of analysis that can greatly enhance our insights in the sediment transport process and help to better understand how complex morphodynamic systems such as tidal inlets and estuaries work. An extended summary is provided in Dutch, that specifically focusses on the application of SedTRAILS for the KPP-BenO Kust program.
