Supporting Data for: \"Experiments on the Morphodynamics of Open Channel Confluences: Implications for the Accumulation of Contaminated Sediments\"

This dataset is the supporting data for a journal paper titled \"Experiments on the Morphodynamics of Open Channel Confluences: Implications for the Accumulation of Contaminated Sediments\"(https://doi.org/10.1029/2019JF005438). The article described a novel confluence flume experiment on both morphodynamics and deposition patterns of contaminated sediments as a function of geometric and flow conditions. The initial equilibrium bed geometry was developed from a mobile bed and then fixed, allowing for subsequent flow velocimetry and sediment feeding. Colored sediments of fine gradation, which mimic contaminated sediments, were then fed to the tributary channel. The dataset included the flow field and bed elevation data collected in the experiment.
