Determining Landslide Drain Lifecycle for Development of Maintenance and Operation Manuals

This proposed research will develop a methodology for preparation of Operation & Maintenance (O&M) manuals for horizontal drains. Building upon existing Oregon Department of Transportation (ODOT) and agency partner data, instrumentation and monitoring will be performed on a series of landslide sites with varying soil/rock conditions and drain ages. Specific objectives include: (1) Develop numerical model leveraging empirical data to determine design parameters and decay in efficiencies for a large range of possible site conditions. (2) Design simple tools to determine generalized and potentially site-specific decay curves in drainage efficiency from measurable data. (3) Provide example of optimal O&M manual for pilot drain using defined needs from Maintenance and Engineering professionals. (4) Provide guidance manual and training for developing performance curves for horizontal drains and recommendations for preparation of O&M manuals for delivery to Maintenance teams.
