How do streams erode their channels?
abrasion/grinding/dissolving materials
What is dissolved load?
a solution of stream water and dissolved materials being transported
What is suspended load?
the largest part of a stream's load is carried in suspension; sand, silt, and clay are carried like this/ load increases during floods
What is bed load?
solid material carried in a stream along the bootom (bed) of the stream channel
Capacity is:
MAXIMUM load it can carry -- greater the volume of water, the greater the load it can carry.
Competence is:
measured by the largest particles a stream can carry. Velocity increases competence.
Alluvium
sorted material deposited by a stream
Delta
sediment formed where a stream enters a lake or ocean/often triangular in shape
Natural levee
ridge,made up of coarse sediments, that parallel some streams/caused by overflowing streams
Narrow valleys
V-shaped valley; waterfalls and rapids are typical features
wide valleys
formed after the stream has made a narrow valley/usually has a floodplain
floodplain
when river overflows, this plain gets flooded
