Over time, the water erodes the river's banks and river beds changing it flow pattern
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.
Along with friction, turbulence slows down the waters flow and also may erode the stream bed
A stream bed is the bottom (floor) of the stream.
Along with friction, turbulence slows the stream's flow and may also erode the stream.
Particles of sand, gravel, or soil carried by the natural flow of a stream on or immediately above its bed. Also known as bottom load.Read more: bed-load
volume of water flowing in the stream
=A perennial stream or perennial river is a stream or river (channel) that has continuous flow in parts of its bed all year round during years of normal rainfall. During unusually dry years, a normally perennial stream may cease flowing, becoming intermittent for days, weeks, or months depending on severity of the drought.=
Perennial is a stream or river that has a continuous loop of a flow in parts of a stream bed all year round during years of normal rainfall. A intermittent is a stream or river which carries water in a considerable portion of the time, but ceases to flow occasionally or seasonally because bed seepage and evaporation/transpiration exceed the available water supply. That is a summarized form of what each stream are. In conclusion, the difference is the way the stream flows. Perennial is a circular stream that is steady all year long, while a intermittent stream is at a specific timing.
Bed Load
The bed of the stream.
If a rivers slope increases so does water speed. And as more water flows through a river speed also increases due to the volume of flow. As for the stream bed shape , friction affects river speed when the water is deep. Hope i helped!
All streams meander to some extent. The most likely time is when flow is consistent and gradient is uniform. See Braided Stream. When a stream has eroded the steep valleys to genteler slopes, the stream flows more slowly.Now water in the stream erodes along the sides of the stream bed rather than along the stream bottom. === ===
