What is the formula for determining
discharge of a river?
|
Q=AV where Q is discharge, A is the
cross sectional area of the river and V is
the velocity.
|
|
What is bedload?
|
Bedload is the sediment that is carried
along the base of the stream channel by
saltation and traction.
|
|
What are the four methods of sediment transport in a river?
|
Dissolved load, suspension, saltation, and traction.
|
|
What are the three channel types?
|
Straight, meandering, and braided.
|
|
In a meandering stream, where is the velocity greatest?
|
It is greatest just below the surface on the outside of a meander.
|
|
What is stream capacity?
|
It is the amount of sediment that a stream can carry at a given velocity.
|
|
What is stream competence?
|
Stream competence is the maximum particle size a stream can move at a given velocity?
|
|
If velocity increases, what happens to stream competence and capacity?
|
Both stream competence anc capacity will increase.
|
|
What isa delta?
|
It is a depositioanl landform formed when flowing water enters a standing body of water. As velocity decreases, sediment drops out and is depositied wit hthe coarsest sediment closest to the exit point and the finest sediment furhtest away.
