ADDITIONAL INFORMATION

Symposium Description

  • Introduce current research projects by DOGAMI and USGS, including those involving LIDAR, and future map products
  • Present some risk reduction information and possible future risk management practices

Goals

  • Provide a forum for the exchange of landslide information between government agencies, academia, and private industry
  • Review current DOGAMI/USGS partnership and project directions
  • Promote risk management
  • Form preliminary statewide landslide advisory group (for reducing damage from landslides)
  • Improve state-of-practice regional landslide analyzes and assessments
  • Obtain ideas for 2009 Geological Society of America conference in Portland

Symposium and Field Trip Sponsors

  • Oregon Department of Geology and Mineral Industries (DOGAMI)
  • U.S. Geological Survey (USGS)
  • American Society of Civil Engineers (ASCE) Council on Disaster Risk Management (CDRM)
  • ASCE Oregon Section’s Geotechnical Group (GG)
