For those of you interested in landslides, I'm presenting my dissertation
proposal next Monday at 10.
Cheers,
Ronda

*Title: Predicting Climate Change Impacts on Shallow Landslide Hazards at
Regional Scales*



Abstract:

In the Western U.S., landslides are a major mechanism of landscape change.
Landslides transport sediment to streams, often contributing to damage of
downstream infrastructure. Site-specific traits (e.g., slope) control the
pre-conditioning of hillslopes to failure, while triggering factors (e.g.,
rainfall) lead to losses in strength initiating landslides. There is need
to unify geologic and hydroclimatic research to provide regional-scale
landslide prediction for resource management and climate adaptation
strategies. This dissertation develops a landslide probabilistic model
that derives hillslope inherent and dynamic stability driven by hydrologic
simulations from the Variable Infiltration Capacity (VIC) model.
Uncertainty is notable in landslide modeling and explicitly accounted for
through Monte Carlo realizations of hillslope “factor-of-safety” from
spatially variable parameter distributions used to determine dynamic
landslide probability. Climatology, soil, and topography control the
dynamic nature of hillslope stability and empirical information from mapped
landslides will be used to further improve the discriminating ability of an
integrated model. This modeling approach will be designed to facilitate
prediction of future shallow landslide hazards given projected hydrologic
change in recharge driven by global climate models. Additionally, this
dissertation will use the modeling methodology to examine indirect effects
from climate change on stability, such as changes in fire regimes. The
propagating effects of climate dynamics on geomorphology will be used to
estimate risks to infrastructure such as roads from landslide hazards. A
proof-of-concept application will be tested in North Cascade National Park
Complex, a rugged region with nearly 2,700 m of vertical relief, covering
2,757 km2 in northern Washington State.
