Understanding how water moves through landscapes and how that movement shapes hazards.
Landsliding along the Nooksack River, WA
For example...
How does groundwater affect landslide hazards in Washington glacial terraces?
1
Rain falls on steep topography composed of different layers of sediment
2
Groundwater perches on sediment layers of low hydraulic conductivity
3
At the grain scale, the way water exerts pressure as it occupies pore-space and flows around grains can destabilize the soil body and cause landsliding.
