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.
Sediment Movement During High Flow
Detailed Description
Water is a major way that sediment is transported from one area to another. Waterways such as streams and rivers often transport small particles of suspended sediment downstream during regular, low-flow conditions, but during high-flow events such as storms, fast-moving water can stir up additional suspended sediment, and has the energy to transport much larger pebbles and cobbles.
The total sediment that a waterway might be moving during a particular period of time is divided into two parts: suspended sediment and bedload.
Suspended sediment refers to the tiny particles of organic and inorganic material that are light enough that when they are disturbed, they stay suspended in the water column for long periods of time and can be transported great distances.
Bedload refers to the sediment that is too heavy to remain suspended in the water, but that can still be moved by fast-flowing water. Smaller pebbles might bounce or skip along the bottom of the waterway (this is also known as saltation), while larger rocks or even boulders might roll along the streambed.

Total Sediment Load
Total Sediment Load Total sediment load is the amount of sediment transported by a waterway past a given point over a given amount of time. Total sediment load has two components: suspended sediment and bedload. Suspended sediment refers to the tiny particles of organic and inorganic material that are light enough that when they are disturbed, they stay suspended in the water column for long...
