Bedload Transport on the Kootenai River near Bonners Ferry, ID (Part 4)
An underwater video camera was mounted on a Helley-Smith bedload sampler and set on the bottom of the river during a flow of around 32,000 cubic feet per second (bankfull). The video was titled with the GPS coordinates, date, and time.
Part 4 was recorded upstream of Shorty's Island in the river's meander reach. Dunes of sandy sediment are clearly visible.
