Abstract
The Ottawa Valley Landslide Project is, in part, a pioneering study of the capabilities of geophysical techniques to provide regional-level reconnaissance surveys of several critical parameters or factors related to landsliding and surface deformation of sensitive marine (Leda) clay near Ottawa. In two study areas, variations in pore-water salinity and soft-sediment stratigraphy, as well as definition of the bedrock topography, and potential ground response to seismic shaking were determined using electrical conductivity, electromagnetic resistivity, high-resolution seismic, and ground penetrating radar surveys. Results were confirmed at strategic boreholes through downhole geophysical logging and geotechnical testing. The geophysical techniques were shown to offer rapid and cost-effective tools to contribute to regional hazard assessment and modeling ground response to earthquake shaking.
