1. straight
2. meandering
3. braided
4. anastomosing

1. dissolved load
2. suspended load
3. bedload (saltate or roll/creep)

1. gradient (vertical distance/horizontal distance)

2. bank stability (vegetation, sediments, etc.)

3. bedload (how much sediment you have within the flow)

1. river gradient

2. friction (slows it down)

3. amount of water entering the system (# of tributaries)

4. discarge (amount of water passing over a specific point at a specific time (volume/time))

1. low flow: water is confined to channel and is well below the banks

2. high flow/bedload: water in channel but banks are full

3. overbank/flood: water escapes banks, spills onto the surrounding area (flood plain)

1. downcut

2. headwater erosion

1. move over landscape rather than through

2. have a graded profile (lateral)

1. really narrow

2. high velocity

3. found closer to mountains

the "curviness" of a river

actual path or channel length/ shortest path or down valley length

1. braided rivers have easily erodable banks while anastomosing rivers have cohesive banks that don't tend to move as much

2. the width to depth ration of anastomosing is less than braided 

3. anastomosing's main movement is veritcal while braided's main movement is lateral

1. longitudinal bars

2. traverse bars

3. cross channel bars

1. They aggrade (the level rises by deposition) and migrate downstream.

2. they are found more often in upper reaches where there are coarse sediments and pebbles

3. strat: planar at the bottom, x-beds, finer sands in between from channel

1. they are broad and lobate

2. made up of finer sediments b/c they are found in the lower reaches 

3. during floods you get mega-ripples

4. structures: ripples, dunes, trough cross beds

1. are found where smaller channels enter larger channels

2. flow is more lateral or oblique

3. x-beds show flow perpendicular to main flow

4. strat: trough x-beds, scouring, coarse sed (channel base), fine sed (bar top), abrupt FU sequence, wide stacked lobes

velocity varies

1. high velocity = erosion = outer bend

2. low velocity = deposition = inner bend

1. point bar: where the velocity is low and sediment is deposited

2. cut bank: where the velocity is high and the land is eroded

3. oxbow lake: the really sinuous part of the river gets cut  off

4. meander scar: a dried up oxbow lake

5. neck: the part that cuts off the oxbow lake

6. crevasse splays: rising water causes levee to be breached and water spills out onto floodplain

7. avulsian: breached side of channel where new sinous course starts on flood plain

the name gives it away duhhh

it's straight and has LOW sinuosity

at headwater where energy is very high

also found in areas where flow path may be controlled by underlying geology

NO. no ones likes them. 

jk. they're rare

1. the upper and lower delta plain

2. the delta front/slope

3. the prodelta (submarine shelf)

What happens when glacial lakes freeze?

1. sediment provenance/source

2. transport direction

3. geometry

4. chronology

1. accomodation space

2. tectonics and sedimentation

3. climate

4. organics

provides the weathered products/sediments

source tells you the mineral type

1. size of the sediment is related to energy

2. roundness related to distance

3. imbricated to paleoflow direction

4. structures related to paleoflow direction and type
