Bedload Transport on the Kootenai River near Bonners Ferry, ID (Part 2)

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 2 is a clip from the first video, showing the mobilization of cobbles on the bottom of the river's braided reach.
