cilt and dirt and also rocks can settle along a stream. over time this can effect the dimmessions of the stream. deposition would be the depositing of rocks dirt and cilt or the settling of these materials. this could make the walls closer in or the depth to become smaller ultimately makeing the stream smaller, allowing less water to flow.
What else can I help you with?
What are two ways to increase the amount of erosion or deposition in a stream-table experiment?
You could increase the amount of water flow, or increase the angle of water flow to increase the amount of erosion. Both will increase the amount of the resultant deposition.
Which characteristic exists at an erosion deposition interface in a stream where equilibrium occurs?
A characteristic that exists at an erosion-deposition interface in a stream where equilibrium occurs is a balanced sediment load. This means that the stream has enough energy to transport sediment in erosion zones, but also deposits sediment in deposition zones due to reduced energy. This equilibrium results in a stable channel shape and flow pattern.
When a stream has reached a balance between erosion and deposition it is called what?
When a stream reaches a balance between erosion and deposition, it is called a "graded stream." In this state, the stream has achieved a stable profile, where the energy of the flow is perfectly matched to the sediment load, allowing for a consistent transport of materials without significant changes in channel shape or structure. This equilibrium often results in a smooth, gently sloping channel.
How does changing the slope of the stream table produce different results?
Changing the slope of the stream table affects the speed and direction of water flow. A steeper slope creates faster water flow, which can result in more erosion and deposition. Conversely, a flatter slope slows down water flow, leading to less erosion and deposition. These changes in flow dynamics can cause differences in the shape and size of channels, as well as the amount and distribution of sediment carried by the water.
What causes a stream to meander?
A stream meanders due to a combination of factors such as the flow of water, the slope of the land, and the type of sediment in the streambed. Erosion and deposition processes also play a role in shaping the curves and bends of a meandering stream.
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.
What transport processes would likely dominate in a muddy stream?
In a muddy stream, sediment transport processes such as erosion, sedimentation, and deposition would likely dominate. The turbulent flow in the stream can cause erosion of sediment from the streambed, leading to the suspension and transport of the sediments downstream. Sediments can also settle out and deposit in areas of slow-moving water or when the flow velocity decreases.
How does the variation in the speed of stream flow affect stream depth and sediment deposition?
The variation in stream flow speed significantly influences both stream depth and sediment deposition. When the flow speed increases, it has the capacity to erode the streambed and banks, leading to deeper channels. Conversely, when the flow slows down, sediment carried by the water settles out, resulting in sediment deposition and potentially shallower areas. This dynamic relationship affects the overall morphology and ecology of the stream system.
Is a split formed by erosion or deposition?
A split can be formed by both erosion and deposition. Erosion processes like weathering and water flow can create splits in rocks or landforms, while deposition of sediments can also fill in gaps and create splits in formations.
Are aquifers a source of erosion or deposition?
Aquifers are not a source of erosion or deposition. They are underground layers of rock or sediment that hold water, which can flow through them. Aquifers can be eroded by the slow movement of water through them over time, but they do not cause erosion or deposition themselves.
What is the effect of vegetation on bank erosion and the shape of the stream channel over time?
Vegetation along stream banks can help stabilize soil, reduce erosion, and improve bank structure. Over time, the roots of plants can strengthen the bank, preventing it from eroding and shaping the stream channel by guiding the flow of water and sediment deposition. This can lead to a more stable and natural stream morphology.
What is the capacity of a stream related to?
The capacity of a stream is related to its ability to transport sediment and water, which is influenced by factors such as flow velocity, channel shape, and gradient. It refers to the maximum amount of sediment that a stream can carry without deposition. As the flow increases, the stream's capacity also rises, allowing it to transport larger and more sediment. Understanding stream capacity is crucial for managing erosion, sedimentation, and aquatic habitats.
