Images of the dye tracer plumes generated by food dye released from a hypodermic needle via a peristaltic pump into the water flow in the experimental flume under the two different flow regimes. a Close up overhead image at the point of release of the dye plume generated in the laminar flow; b close up overhead image at the point of release of the dye plume generated in the turbulent flow; c overhead image of entire flume showing the structure of the dye plume generated in the laminar flow; d overhead image of the entire flume showing the dye plume generated in the turbulent flow
