Fluvial process
|
1 process associated with running water2 Most important force shaping the world3 Flows downhill by gravity
|
|
Running water can
|
1. Weather2. Erode3. Transport4. Deposit
|
|
Weathering 2
|
Hydraulic action - sheer force of water flow flowing and battering rock or soilAbrasion- all the sediments the river is transporting scrape against rocks

Sheer force of water flow flowing and battering rock or soil
|
WEATHERINGhydraulic action
|
|
All the sediments the river is transporting scrape against rocks and soil
|
WEATHERINGAbrasion
|
|
Erosion
|
1Weathered material is removed from channel by flowing water2 stream channel itself is an example of an erosional feature
|
|
Transportation
|
River carries eroded material as it flows
|
|
All of the transported material
|
Stream Load
|
|
Solid bits floating in the water being transported
|
Suspended load
|
|
Broken down into molecular constituents and transported in the water
|
Dissolved load
|
|
Big rocks that are too heavy and get bounced along the bottom of river
|
Bed Load
|
|
Deposition depends on the streams
|
CAPACITY- Velocity. Higher velocity, higher ability to transport sediment
If the stream slows down, it will deposit |
|
Deposition
|
When there is too much stream load for the speed of the riverDeltas and Point bars
|
|
Stream Gradient
|
1. streams start by flowing down a series of steps2 lots of flat ground, steep drop off, water falls3 eventually the waterfalls erode away and stream flows down a gently sloping path
|
|
Ungraded
|
How streams start- series of steps with drop offs
