Abstract

The flow of sediments in water is a subject of interest to both engineers and geologists with the resistances to the flow of water and the formation of sediment waves being of particular interest. Our research investigated the formation of these waves under sheer stress. We ran multiple experiments where water and sand was run through a sediment-feed flume at varying sediment feed rates and measured the roughness height of the water and sediment. Once this data was collected and charted, transitions between types of sediment waves appeared. These trends were compared to data from other experiments and appear to show a transition from triangular waves to rounded waves.
