Underwater Installation of Filter Systems for Scour and Erosion Countermeasures, Volume 2: Training Manual

TRB's National Cooperative Highway Research Program (NCHRP) Web-Only Document 254: Underwater Installation of Filter Systems for Scour and Erosion Countermeasures, Volume 2: Training Manual provides training on the underwater placement of filters, and can be adapted into a workshop or distance learning presentations. The project provides guidance on design procedures, material testing requirements, installation alternatives, and quality checklist items for both granular and geotextile filters. Filters are an important countermeasure for stream instability or bridge scour and are essential to the successful long-term performance of hydraulic countermeasures and other erosion countermeasures.

In addition to this guidance, NCHRP Web-Only Document 254, Volume 1 documents the research effort of NCHRP Research Report 887: Guidance for Underwater Installation of Filter Systems.

The training manual is supplemented with video clips (below) and training materials in PowerPoint format.
