Accotink Creek
Accotink Creek is an urban creek and a tributary of Lake Accotink. Accotink Creek suffers from high rates of streambank erosion, which causes the steep, unstable banks seen on the far side of the creek in the above image.

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.
