Erosion - high energy; hydraulic action, abrasion, solution
Transport - variable energy; bed load (rolling or saltation),
suspended load, dissolved
competence - largest piece stream can carry;
capacity - amount of sediment a stream can carry
Deposition - loss of energy; delta - stream meets calm water (usually
ocean), alluvial fan - abrupt change in
gradient, flood plain, levee, meandering stream
- point bar, cut bank, oxbow lake; braided stream - longitudinal bar
Describe the factors which control the energy of a stream. How does energy affect erosion? deposition?
Describe 3 ways in which streams transport sediment load. What size particles are carried by each mechanism?
Compare and contrast competence and capacity.
Describe the three mechanisms for erosion.
Compare and contrast the following: alluvial fan, delta, flood
plain and levee, point bar, and longitudinal bar. Describe the
shape of each, its location, and the cause of the energy loss.
