Transcript of What is Geomorphology

What is Geomorphology?
process
human impact
mass wasting
floods
structure
is structure key?
Historic views of
geomorphic processes
W.M. Davis' geographical cycle
Gilbert (1877), Hack (1960)
uplift and denudation occur at the same time and govern slope geometry
modern view
it's more complicated
What is stability? How does it relate to equilibrium?
Consider: Are landforms stable systems?
scale is important
the study of landforms...
...and the processes that affect them
why should we study
geomorphology?
to understand how the landscape came to be
to predict and prepare for future change
to harness resources to improve the human condition
hazards
climate change
erosion
climate
what does climate have to do with geomorphology?
historic
erosion
runoff
drought
vegetation
tree canopy
biotic influences
stream flow
ice
weathering
isostatic adjustment
process form
Examples
climate form
structure form
fault-block mountains

so are feedback and thresholds
streamflow
static equilibrium
steady-state equilibrium
stable equilibrium
unstable equilibrium
Disturbance
Threshold
Tipping point
