• Abstract:
  The Office of Geotechnical Engineering (OGE) of the Ohio Department of Transportation (ODOT)
  
  recognizes the need to develop a strategy to provide timely preventive maintenance to avoid on-set of
  
  large or catastrophic slope failures. Furthermore, with limited financial resources, the OGE is forced to
  
  make rational decisions on the priority of various landslide (slope failure) maintenance and remediation
  
  needs. To address these issues, this research project was undertaken with the following objectives: (a)
  
  Develop a field validated landslide geological hazard rating matrix, (b) Develop field reconnaissance
  
  forms in paper format and electronic format (window plus ArcPad), (c) Develop and deploy a web
  
  enabled, GIS based landslide database, and (d) Develop a user’s manual and training materials for the
  
  landslide geological hazard database. Based on synthesis of literature review of existing practices,
  
  ODOT in-house expert opinions, and knowledge of prevalent Ohio geological formations in landslide
  
  prone areas, the principal investigator developed the ODOT specific landslide hazard rating system,
  
  together with the field site reconnaissance form. A pilot database containing 39 landslide sites was
  
  compiled and statistically analyzed to ascertain the reasonableness of the hazard rating outcome. A
  
  web accessible landslide database in a GIS platform was developed, pilot tested, and deployed. In
  
  addition, a user’s manual was developed to assist training of the future users of the system. The
  
  benefits from full implementation of the landslide database and landslide hazard rating matrix include:
  
  (a) elimination of excessive paper work, (b) near real-time monitoring and data management, (c)
  
  centralized information, (d) uniform data collection and reporting, (e) enhanced data sharing.
  
  Furthermore, the Ohio Department of Transportation can reap the benefits of cost saving due to early
  
  stage detection of landslide and taking pro-active remediation measures.
