Behavioral Comparison Of Fluorescent Tracer Sediment To Lightweight Polystyrene Sediment Of The Lower Mississippi River Physical Model (Lmrpm), Julia C. Mudd

LSU Master's Theses

A lightweight, unexpanded polystyrene sediment with a specific gravity of 1.05 and a D10, D50 and D90 of 0.250 mm, 0.425mm, and 0.800 mm, respectively, is utilized in the Lower Mississippi River Physical Model (LMRPM) at Louisiana State University to mimic the sand transport of the Lower Mississippi River. While the black model sediment is easily visible against the stark white of the LMRPM, the relative homogeneity of the sediment particles and the opaqueness of the model channel make it difficult to closely study sediment dynamics during an experiment. For this reason, a tracer sediment that is marked with fluorescence …
