It is because if a stream gets bigger, it is allowed to carry more sediment. More sediment means more erosion.
it is gradient, discharge and load.
what are three factors that affect rate of stream erosion
The slope or gradient of the stream is the most likely factor to affect the amount of erosion. Steeper slopes result in higher velocities, which in turn increase the erosive power of the stream. A steeper slope also allows the stream to carry larger sediment and potentially cause more erosion.
Stream Load is the amount of material a stream can hold as it flows. As a stream flows it causes erosion, and this erosion is carried about as material in the stream. As too much is eroded, the extra material will fall to the bottom, or push it's way to the sides.
wind erosion
The gradient of a stream affects the speed of the water as it moves downstream. The steeper the gradient, the faster the water moves.
a stream is most likely widen by erosion
A young stream is typically characterized by a steep gradient, fast flow, and erosion of its channel. As a stream matures, it becomes more meandering, has a gentler gradient, and tends to deposit sediments in its channel. An old stream has a low gradient, meanders extensively, and has a stable floodplain with significant sediment deposition.
i think its the farts in this world
There are three factors that affect stream erosion. These are water velocity, shape, size and depth of channel, and stream capacity to transport eroded materials.
A mature stream causes more erosion than a young stream, due to the pure fact that theres more curve in a mature stream causing the sediments to shift more frequently.
An increase in gradient will generally increase stream velocity.
