A hose measuring 2.5 cm in diameter (1 and 2) connects to a pump (not drawn). The hose was first placed above a measuring jug (position 1) into which fluid is pumped. The balance recorded the mass fluid within the jug at 1 s intervals, and using a known density, was used to calculate the flux of the fluid entering the channel (Qi). The hose was then attached to the experimental tank (position 2) for the experiment. The slope angle (β) was adjusted between 5, 10, 20, and 45 degrees. Additional plexiglass inserts were clamped inside the channel, reducing the channel width to 9, 7, 5, and 1 cm, respectively. At the down-slope end of the tank, a jug positioned on top a balance collects the outflowing fluid, and the outgoing flux (Qo) was calculated. Two cameras (A and B) capture video footage of the entire length of the experimental tank. The cameras were positioned at 90 degrees to the plexiglass wall of the tank, including the experiment timer and LED lights used for syncing imagery between cameras.
