Sediments begin to be Deposited. This occurs or is been experienced mostly at the river mouth, where its water enters a larger body, like the sea. (i.e. at its distributaries).

How sediment control erosion?
Typically, when the earth's surface is exposed to the impacts of rainfall, there is an increase in the volume and velocity of runoff. This sets off a chain reaction that results in the transport and deposition of sediment, reduced stream capacity, and ultimately increased stream scour and flooding.
What is the total sediment load transported by a stream?
carrying power
Why do sediments settle to the bottom of a lake or sea?
Sediment settles on the bottom of the lake or sea ultimately because it is heavier than water. Sediment begins as dirt or fragments of rock on land. When precipitation (rain) or flooding occurs these fragments are carried along with the water to the nearest stream, river, or other water reserve. The sediment that is carried into a lake or pond then sinks to the bottom of the body of water. The sediment that finds its way into moving water is ultimately emptied into the ocean, or whichever body of standing water the river or stream flows. Once the sediment reaches the stagnant body of water it will sink to the bottom.
What are the benefits of stream lined bodies?
stream lined body of a fish helps to reduced friction
What causes a river to deposit sediment?
Most sediment washes or falls into a river as a result of mass movement and runoff. Other sediment erodes from the bottom or sides of the river. Wind can also drop sediment into the water. Hope I helped! -DorkyGeek77

What factor determines the competence of a stream?
The competence of a stream is determined by the stream's velocity and the size of the sediment it can transport. Streams with higher velocities and larger sediment sizes are typically more competent and can transport larger particles.
When a stream emerges from a mountain canyon the stream slope is greatly reduced as a result the sediment is deposited within a short distance and forms a or an?
Alluvial Fan
What stream characteristic is measured by the size of the largest particle that a stream can move?
The measure of the largest particles a stream can carry is capacity.
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.
How does a river's velocity affect its competence and capacity?
the competence and capacity of a steam depend on a streams velocity and discharge. Because the velocity and discharge of a given stream are not constant , the competence and capacity of a stream are not constant . competence and capacity vary along a stream and change throughout the year.

What is a streams bed load?
Sediment that is carried by a stream along the bottom of its channel.
Is the water in a stream called sediment?
No, the solids the water carries is the sediment.
What is the difference between the capacity and the competence of a stream?
The competence of a stream shows the maximum single load i.e. individual large rock, that the stream can move. It ignores the rest of the load in the river. The capacity would include the rest of the finer load so it is the whole load of the stream (including the large rock) Thus capacity will always be more than competence.
What is sediment that moves along the bed of a stream?
called a bed load its sediment that moves along the bed of a stream by rolling bouncing or sliding
What is a braiding stream?
A braided stream is a stream that has small channel capacity with respect to its sediment supply. Basically, there is not sufficient room within the stream valley to deposit all of the sediment and therefore, small islands of sediment form within the stream giving it a braided appearance. Braided streams generally occur at high gradients.
