Dr. Gregory R. Brooks P.Geo.

Research Scientist

Conducts applied geomorphic research in the fields of geomorphology, paleoseismology, and engineering geology.

Current research and/or projects


I am geomorphologist and have been with the Geological Survey of Canada (GSC) since 1992.  Most of my research has been in the fields of natural hazards and to a lesser extent climate change.  Themes that I have researched include the chronology of sensitive clay landslides in eastern Canada, the geomorphic effects of flooding during the 1996 Saguenay flood disaster, geomorphic factors influencing Red River floods, and the occurrence of extremely low-water levels in the upper Great Lakes.  Currently, my research is investigating evidence of paleoseismicity preserved in lake basins.  My research results are published in scientific journals and in GSC reports that can be searched for in the Geoscan database (http://geoscan.nrcan.gc.ca/geoscan-index.html). 

Research and/or project statements

Current Research Projects:

  • Evidence of paleoseismicity in eastern Canada.
  • Age, extent and triggers of submarine landslide deposits in lake basins.
  • Geomorphology, chronology and triggers of sensitive clay landslides.

Professional activities / interests

  • Long-term interest in natural hazards, including the paleoseismology, seismic microzonation, and the geomorphic effects of extreme floods
  • Reviews environmental assessments relating to the development of hydroelectric dams in Canada and their impact on fluvial geomorphic processes.  I have testified at environmental review hearings on behalf of the Natural resources Canada.
  • Member of Executive of Canadian Geomorphological Research Group (CGRG) in 2009/10 to 2011/12.  CGRG President in 2010/11.
