Hydrology and Fluvial Geomorphology Flashcards
1
Q
3 flow patter types
A
- laminar
- turbulent
- helicoidal
2
Q
laminar flow
A
sheet-like flow of water, requires very flat smooth riverbed, almost theoretical
3
Q
turbulent flow
A
circular motion of currents - erratic eddies, associated with waterfalls and rapids, erosional, rough bed - increased friction created eddies
4
Q
helocoidal flow
A
corkscrew movement of water, in the thalwag, involved in meander formation
5
Q
3 channel types
A
- straight
- meandering
- braided
6
Q
4 erosion methods
A
- abrasion
- attrition
- hydraulic action
- solution / corrosion
7
Q
4 transport methods
A
- suspension
- solution
- traction
- saltation
