Stream capacity is a measure of the total sediment (material other than water) a stream can carry. Stream competence reflects
the ability of a stream to transport a particular size of particle
(e.g., boulder, pebble, etc).
What is the difference between capacity and competence quizlet?
Describe the difference between capacity and competence. CP-
the maximum load of solid particles a stream can carry
. The greater the discharge, the greater the capacity. … Streams with faster velocity have higher competence.
What is the difference between Stream competence and stream capacity quizlet?
What is the difference between a stream’s competence and its capacity? – Stream’s competence:
largest sized particle being moved by the stream
. – Stream capacity: total discharge of sediment the stream is transporting.
What is the competence of a stream quizlet?
Competence of a stream
measures the largest PARTICLES it can transport
. A stream’s competence increases with it velocity.
What is River competency?
River Competence: Rivers and streams carry sediment that ranges in size from clay (smallest) to boulders (biggest). The “competence” of a river or stream refers
to the largest particles that a river can transport
. … Several smaller streams have combined higher in the Sierras to generate this river.
What is the load of 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.
What factors affect the amount of sediment a stream can carry?
Rainfall, whether slight or heavy can
affect water flow and sediment transport. The extent to which a weather event will influence sediment transport is dependent on the amount of sediment available. Snowmelt in a glaciated area will result in a high sediment load due to glacial silt
10
.
What is the maximum load a stream can carry called?
The faster the current, the heavier the particle that can be transported.
Stream capacity
is the maximum amount of solid load (bed and suspended) a stream can carry.
In what 3 ways does a stream transport its 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).
Which are two most common minerals in detrital rocks?
The most abundant detrital minerals in sediments are
quartz and clays
. Quartz is an abundant mineral in many rocks.
What are the three main types of loads that a river carries?
- Stream current.
- Suspended load.
- Solution load (dissolved)
- Bed load.
- River bed.
What is the dissolved load of a stream?
Dissolved load is
the portion of a stream’s total sediment load that is carried in solution
, especially ions from chemical weathering. It is a major contributor to the total amount of material removed from a river’s drainage basin, along with suspended load and bed load.
What are the 3 factors that influence how much sediment a river carries?
What factors affect a river’s ability to erode and carry sediment? A river is a
dynamic system> A river’s slope, volume of flow, and the shape of it’s stream bed
all affect how fast the river flows and how much sediment it can erode.
What increases the competency of water?
How Can You Improve your Water Skills?
Learn to swim safely
and make sure all children and adults master essential swimming skills, such as knowing how to enter and exit the water, float, tread water, and swim a short distance.
What is river capacity?
The capacity of a stream or river is
the total amount of sediment a stream is able to transport
. … Stream capacity is often mistaken for the stream competency, which is a measure of the maximum size of the particles that the stream can transport, or for the total load, which is the load that a stream carries.
How can competence change in a river?
The velocity of the flow of water is directly affected by channel slope, the greater the slope the greater the flow velocity. In turn,
an increased velocity of water flow
increases stream competence.
