Running Water
stream - channelized flow of water
energy: gradient
= vertical/horizontal, channel shape, channel roughness, vegetation
Processes: erosion , transport,
deposition
Deposition - low energy; delta - stream meets calm water (usually
ocean), alluvial fan - abrupt change in
gradient, flood plain, levee, meandering stream
- point bar, braided stream - longitudinal bar
Describe the factors which control the energy of a stream. How does
energy affect erosion? deposition?
Compare and
contrast the following stream
deposits: point bar, longitudinal bar,
flood plain, alluvial fan, delta
Compare and
contrast braided streams and meandering streams.
