What constitutes the highest percentage of the annual sediment load moved by a stream?
what term generally refers to the highest percentage of the annual sediment load moved by a stream? suspended load.
Which stream load carries the largest sediment?
Bed load rolls slowly along the floor of the stream. These include the largest and heaviest materials in the stream, ranging from sand and gravel to cobbles and boulders. There are two main ways to transport bed load: traction and saltation.
What describes the total sediment load transported by a stream?
The maximum load of sediment that a stream can transport is called its capacity. Capacity is directly proportional to the discharge: the greater the amount of water flowing in the stream, the greater the amount of sediment it can carry.
What determines the maximum sediment load of a stream quizlet?
The greater the discharge, the greater the stream's capacity for hauling sediment.

What is stream abrasion?
Abrasion occurs as sediment in a stream collides with rock in and along the stream. Pieces of rock are chipped away and rough edges in rocks and sediments themselves become rounded. The bedrock beneath streams is also eroded by abrasion. Sediment flowing in the water can cut deeply into the bedrock.
What are types of sediment load?
When particles are eroded and transported by wind, water, or ice, they become part of the transport medium's sediment load. There are three categories of load that may be transported by an erosional agent: dissolved load, suspended load, and bedload.
What is a stream load quizlet?
Stream load. All the materials that are transported in a stream. Dissolved load.
What term describes the total sediment load transported by a stream quizlet?
STUDY. capacity. what term describes the total sediment load transported by a stream? suspended load.
What term is used for the maximum size of particles that the stream is capable of transporting?
CP-the maximum load of solid particles a stream can carry. The greater the discharge, the greater the capacity. CM- the maximum particle size a stream can transport. Streams with faster velocity have higher competence.
What is the maximum particle size a stream can transport?
What is the largest particle size that a stream can transport at a velocity of 5? What is the largest particle size that a stream can transport a velocity of 5 centimeters per second? Answer: it's 3 Sand.
What are the three components of sediment load in a stream?
The total load (quantity of sediment) of a stream can be described as consisting of three components:
- the bed load – materials bounced along the stream bottom.
- the suspended load – material carried in suspension in the stream water.
- the dissolved load – material carried as dissolved solids in the stream water.
What three factors are likely to cause high sediment load in a river?
Factors such as relief, channel slope, basin size, seasonality of rains and tectonic activities control sediment loads in rivers. Human interventions in the form of reservoirs for water storage have impounded and trapped huge sediment loads on the continental parts.
What is stream abrasion quizlet?
the wearing down of rock particles by friction due to water or wind or ice.
How do streams transport their load?
Streams transport their load of sediment in three ways: in solution (dissolved load) in suspension (suspended load) or scooting or rolling along the river bottom (bed load).
What is stream load quizlet?
Stream load. All the materials that are transported in a stream. Dissolved load.
What is a rivers sediment load?
A river's sediment load is computed from water discharge and sediment-concentration data, and represents the flux of sediment transported by the river; it is usually expressed as mass per time, for example, tons per year (tons/yr). Most of a river's sediment load occurs during floods.
Which part of the load transported by streams contains boulders quizlet?
In a suspended load, where streams carry the largest part of their load, usually is made up of fine sand, silt, and clay, but larger particles may be transported during flood stage. In a bed load, coarse materials including course sands, gravels, and boulders move along the bed load by rolling, sliding, or saltation.
How do streams transport sediment?
Streams transport their load of sediment in three ways: in solution (dissolved load) in suspension (suspended load) or scooting or rolling along the river bottom (bed load).
What is the suspended load of a stream?
Almost all the world's streams carry sediment that originates from erosion processes in the basin that feed the streams. Sediment carried in a stream is classified as either suspended load or bed load. The suspended load is the fine-grained (clay and silt) sediment that remains in water during transportation.
What refers to sediments deposited from streams?
Alluvium refers to stream deposits, mainly sand and gravel. true.
When a stream has a greater supply of sediment than it can carry?
Aggradation (or alluviation) is the term used in geology for the increase in land elevation, typically in a river system, due to the deposition of sediment. Aggradation occurs in areas in which the supply of sediment is greater than the amount of material that the system is able to transport.
What are the three types of sediment carried by a stream or river?
The total load (quantity of sediment) of a stream can be described as consisting of three components: the bed load – materials bounced along the stream bottom. the suspended load – material carried in suspension in the stream water. the dissolved load – material carried as dissolved solids in the stream water.
Which is the largest sediment type that could be carried by a stream flowing at a velocity of 75 centimeters per second?
which is the largest sediment type that could be carried by a stream flowing at a velocity of 75 centimeters per second? pebbles.
What is the largest rock particle that can be transported by a stream with a velocity of 250 centimeters per second?
A stream flowing at a velocity of 250 centimeters per second is transporting sediment particles ranging in size from clay to cobbles.
What are types of sediment loads?
When particles are eroded and transported by wind, water, or ice, they become part of the transport medium's sediment load. There are three categories of load that may be transported by an erosional agent: dissolved load, suspended load, and bedload.
What factors determine the amount of sediment that will arrive to a stream?
Factors that influence sediment yield The quantity and type of sediment moving through a stream channel are intimately related to the geology, topographic character, climate, vegetational type and density, and land use within the drainage basin.
Which particles of sediment are most likely to be transported as suspended load?
Which particles of sediment are most likely to be transported as suspended load? Suspended load generally consists of fine sand silt and clay size particles although larger particles (coarser sands) may be carried in the lower water column in more intense flows.
How do moving sediments affect the channel of a stream?
During floods, the volume and rate of stream flow increases, and erosion along the stream bed mobilizes sediments that accumulate during times of decreasing stream flow. Erosion carves the sides of stream channels, contributing sediments to streams and allowing the channel to migrate over time.
How are sediments moved by streams?
They can be moved by saltation (bouncing) and by traction (being pushed along by the force of the flow). Smaller particles may rest on the bottom some of the time, where they can be moved by saltation and traction, but they can also be held in suspension in the flowing water, especially at higher velocities.
