If the amount of water in a stream in flood starts to go down what will happen to the sediments the stream is carrying?

As the amount of water in a stream during a flood begins to decrease, the flow velocity will also reduce. This decrease in velocity causes the stream to lose its ability to carry larger and heavier sediments, leading to sediment deposition. Consequently, finer sediments may continue to be transported for a short distance before settling out, while coarser materials will settle quickly as the water slows down. Overall, the sediment load will start to settle on the streambed, altering the stream's morphology.
