Which change in a stream causes deposition?
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.
The lowest elevation limiting stream erosion is called?
The lowest elevation limiting stream erosion is called the base level. It refers to the point at which a stream can no longer erode its bed any lower. This can be either sea level for rivers that flow into the ocean or a lake level for rivers that flow into a lake.
How does turbulence affect the speed of a river and a rivers power to cause erosion?
Along with friction, turbulence slows down the waters flow and also may erode the stream bed
What is Stream bed?
A stream bed is the bottom (floor) of the stream.
Increasing the steepness of a river's bed is LEAST likely to change the size of the discharge of a stream and the?
Increasing the steepness of the river's bed will have no direct effect on the size of the discharge of a stream. Discharge is primarily influenced by the volume of water flowing in the river. Steepness may impact the speed of the water flow and erosion processes, but it won't directly affect discharge size.
How does a river's speed affect its erosive ability?
Along with friction, turbulence slows the stream's flow and may also erode the stream.
What is the difference between a stream bed and a stream bank?
A stream bed is the bottom sediment layer of the stream channel which is constantly inundated with water. It is a saturated layer of sediment inhabitated by macroinvertibrates, algae, macrophytes, and microbes. The particle size of the stream bed material (fine clay vs large rock and boulders) is dependent on geologic region, size of the stream, and stream velocity. The stream bank is the adjacent sloping walls that confine the stream on either side. They are typically not wet except in times of high flows. Banks typically can grow more terrestrial vegetation such as reeds, grasses, and trees.
What are perennial rivers and what is their role in Indian economy which measure phsiographic?
=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.=
What is the difference between a perennial stream and an intermittent stream?
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.
Does a fast moving stream use energy?
Yes, a fast-moving stream uses energy to maintain its flow velocity. The energy comes from gravity, which causes the water to flow downhill and overcome resistance from friction with the stream bed and banks.
Particles that roll and slide along the stream bed make up the of the stream?
Bed Load
What is the measure of th largest particles a stream can carry?
The measure of the largest particles that a stream can carry is typically determined by its stream power, bed material size, and flow velocity. Streams with higher stream power and flow velocity are able to transport larger particles. The largest particles a stream can carry before they settle to the streambed are usually referred to as the stream's "bedload" particles.
