Web22 Apr 2024 · As discharge declines after a flood, the coarse bed load is the first to be deposited in the channel. This material forms the nucleus of bars that grow downstream as the flow velocity is reduced and finer sediment accumulates. With further decreases in discharge the water level progressively falls and the bars are gradually exposed. WebStream discharge is at a maximum and sediment load is generally composed of finer materials. Figure 10y-5: Stream channel near the mouth of a stream.
