TRB's National Cooperative Highway Research Program (NCHRP) Web-Only Document 254: Underwater Installation of Filter Systems for Scour and Erosion Countermeasures, Volume 1: Research Report documents the research effort of NCHRP Research Report 887: Guidance for Underwater Installation of Filter Systems. 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, a training manual for an underwater filter installation workshop is available as NCHRP Web-Only Document 254, Volume 2.
