Streams
(,rivers, brooks, creeks, etc.)

2. Processes
Erosion
Deposition

3. Loads Bed load Suspended load Dissolved load gravel
rounder with greater working
Suspended load
silt
Dissolved load
salt, lime

4. Load Carrying Capacity
Higher velocity flow allow stream to carry:
larger particles
more total load per volume

5. What Happens When Deposition when flow slows
New erosion when flow speeds up

6. Sorting Velocity changes gradually Slowing: deposit heaviest load
Speeding: remove lightest substrate
Result: particles of same size found together (sorted)

7. Common Profile Steep and fast in headwaters Slower near base
Cannot excavate below base level

8. Drainage Patterns Determined by substrate characteristics Trellis
Dendritic
Radial

9. Stream Features

10. Headlands V-shaped valleys Erosion dominates
Alluvial fan at foot of mountain

11. Bottomlands
Flat valleys
Deposition dominates
BUT—flow is variable

12. Bottomland Features
Floodplains
Meanders
Oxbows
Levees
Yazoo streams

13. Meanders Erosion on outside Deposition on inside cutoffs Oxbows
cut bank
Deposition on inside
point bar

22. Meander cutoff

23. Oxbow lake

24. Floods Normal Bank-full discharge ~ 2 years
Deposit on levees, flood plains

25. Meandering river flooding

26. Base Level Delta: deposits choke with sediment
many distributary channels
lobes shift
old sediments subside
