Decrease in stream velocity
A decrease in water velocity usually causes more sediments to be deposited at a location in a stream. This can happen when the stream widens, the channel gradient decreases, or obstacles such as rocks or vegetation slow down the flow of water.
The bed of the stream.
A stream deposition occurs when, in the lower reaches, the flow of water (speed of flow) is reduced. Which is when the heavier sediment falls out and settles on the river bed.
A stream can change direction due to factors such as erosion, sediment deposition, and natural topography. Changes in the streambed, such as rocks or debris, can also influence the flow direction. Additionally, human activities like construction or channel modifications can cause a stream to change its course.
It would be foolish to stop in the middle of a stream or river to change horses. The general idea is that once you have committed to a course of action it is better to continue than it is to change. Used by Abraham Lincoln when he was trying for re-election...but not originated by him.
To calculate the new gradient, we would need the change in elevation over the new 500 km length of the meandering stream. Meandering causes the stream to flow a longer distance within the same elevation drop, thereby decreasing the overall gradient of the stream. This results in the stream having a gentler slope compared to a straighter stream.
