Rivers "carry" their sediment load only as long as the velocity of the water remains high enough to create sufficient turbulence to keep the particles "stirred up". Once a river loses its velocity and the stirring effect of the turbulence subsides the sediment load can no longer remain suspended in the water. At this point gravity takes over and the river begins to "drop" its sediments in a process named deposition.
Now a river going around a curve is like two tires at each end of an axle going around a curve. The tire on the outside of the curve has to move faster than the tire on the inside of the curve since it has a longer radius of travel. So too the water in the river moves faster at the outside of the curve than the water inside the curve. Between the two different water velocities the deposition is going to occur on the inside curve of the river where the water loses its velocity.
Conversely, the opposite of deposition which is erosion will take place at the outside of the curve in the river.
What else can I help you with?
The lowest level to which a stream can erode its channel?
The base level is the lowest point to which a stream can erode its channel. This can be the level of the body of water into which the stream flows, such as a lake or ocean, or an artificial structure like a dam. At base level, erosion stops and sediment deposition begins.
Why the outside of a meandering stream erode more than the inside bends?
The outside of a meandering stream erodes more than the inside bends due to the faster flow of water on the outside of the curve. The higher velocity of water on the outside causes more erosion through processes like hydraulic action and abrasion, wearing away the bank more quickly. Additionally, the outside bends experience more turbulence, leading to increased erosion compared to the inside bends.
What does the rate of stream discharge has to do with erosion and deposition?
rate of stream discharge is directly proportional to the erosion i.e the higher the velocity of the stream then it will erode the rock rapidly while the deposition process will be slow when the velocity will be high.
What is the major factor that determines a streams ability to erode land?
The major factor that determines a stream's ability to erode land is the stream's velocity. Higher velocity streams have more energy and can pick up and transport larger sediment particles, leading to more erosion. Additionally, the volume of water in the stream and the presence of steep gradients can also influence erosion.
How can you describe a process by which a stream can erode its streamed?
A stream can erode its streambed through the processes of abrasion, where sediments carried by the water wear down the bedrock through friction; corrasion, where stones and rocks carried by the water crash into the bedrock; and hydraulic action, where the force of the water itself dislodges and transports sediment. Over time, these processes can deepen and widen the stream channel.
The ability of a stream to erode and transport material depends largely on what?
The ability of a stream to erode and transport material largely depends on its discharge, velocity, gradient, and the size and shape of the sediments. These factors influence how much sediment a stream can carry and how effectively it can erode material from its surroundings.
How does gravity relate to a stream's ability to erode and deposit materials?
Gravity influences a stream's ability to erode materials by pulling them downstream. The force of gravity helps water to carry sediment and erode the streambed. Additionally, gravity plays a role in the deposition of materials by causing sediment to settle out of the water when the stream's velocity decreases.
Would raising the base level cause a stream to gain energy or erode?
Raising the base level of a stream would typically cause the stream to lose energy and deposition could occur rather than erosion. This is because by raising the base level, the stream has less energy to transport sediment, leading to sediment accumulation rather than erosion.

How does a stream base level affect how it downcuts it channel?
Streams can't erode their channels endlessly. there is a lower limit to how deep can a stream erode. Base level is the lowest point to which a stream can erode its channels.
What is curve cause of stream channel cause by erosion?
Are you talking about meanders? when overtime laterally erode the banks (undermine) due to the hydrolic fore of the water. Then then turn to ox-bow lakes due to deposition along the curve and erosion coming into the curve. (bypasses the curve; cuts straight through)
What does a stream's ability to erode mainly depend on?
The amount of water in the stream and the gradient. However if you had two streams both with the same amount of water in them but with one stream flowing down a steeper slope (gradient) than the other, then the steep one has more ability to erode.
Which part of a river experiences erosion?
The outer banks can erode, especially the outside edge of a curve in the river. The bottom can also be down cut.
What does the rate of stream discharge has to do with erosion and deposition?
rate of stream discharge is directly proportional to the erosion i.e the higher the velocity of the stream then it will erode the rock rapidly while the deposition process will be slow when the velocity will be high.
