6.20. (10/2) Facies Models Flashcards
1
Q
how do you numerically model meandering/pool-riffle rivers?
A
shear stress τ0 vs τcritical
2
Q
what do numeric models do?
A
predict behaviors
3
Q
what does process mean?
A
numeric model
4
Q
what does deposit mean?
A
facies model
5
Q
what does facies mean?
A
all of the characteristics that contain clues about the transport process + deposition
6
Q
What does a meandering/pool-riffle river’s facies model look like?
A
floodplain: fine grains
Bars: sand and bedforms
channel: rounded rocks, gravel & sand
7
Q
What is the forward model/problem?
A
it is predicting the future
8
Q
What is the inverse problem? How do we solve them?
A
looking at the end result and figuring out how you got there
*using deposits-> facies model
