What factor determines the largest particle A stream can transport?
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 material carried by a stream?
Stream load is a geologic term referring to the solid matter carried by a stream (Strahler and Strahler, 2006). Erosion and bed shear stress continually remove mineral material from the bed and banks of the stream channel, adding this material to the regular flow of water.
How is a streams discharge related to its carrying capacity?
The greater the discharge and velocity is in a stream, the greater the stream's carrying capacity.
What are the three ways a stream will carry its load?
Explain the three ways in which a stream carries its load. A stream's load is all the material the stream carries, including material in solution, in suspension, and as bed load.
What is stream transportation?
Stream Transportation Large particles rest on the bottom, typically anything larger than sand, is called bedload , and may only be moved during rapid flows under flood conditions. They can be moved by saltation (bouncing) and by traction (being pushed along by the force of the flow).
What is the capacity of a stream?
The capacity of a stream or river is the total amount of sediment a stream is able to transport. This measurement usually corresponds to the stream power and the width-integrated bed shear stress across section along a stream profile.
Which particles will be transported by a stream?
Streams carry dissolved ions as dissolved load, fine clay and silt particles as suspended load, and coarse sands and gravels as bed load. Fine particles will only remain suspended if flow is turbulent.
How is stream load transported?
Stream competence is the largest size material the stream can move under a given discharge. Bed load is that which is moved across the bed of the channel. Bed load is transported in two ways, traction, which is a scooting and rolling of particles along the bed. The second is saltation, a bouncing-like movement.
How is stream capacity measured?
The capacity of a stream or river is the total amount of sediment a stream is able to transport. This measurement usually corresponds to the stream power and the width-integrated bed shear stress across section along a stream profile.
