Slope-off-slip? off..? what?

Somethin' i learned about rivers is a slip off slope. Its formed when the sediments are removed from the outer bank are carried forward by the flow of the water to the inner bank and deposited.Deposition occurs because the friction between the inner bank and the water is greater than at the outer bank, reducing its velocity. With excessive deposition, the water at the inner bank gets shallower, resulting in a slip off slope. BAM, thats whatsuup
