Countermeasures to Protect Bridge Abutments from Scour

The objective of this research is to develop and validate selection criteria and guidelines for the design and construction of countermeasures to protect bridge abutments and approach embankments from scour damage. The countermeasures considered shall include but not be limited to: (1) riprap at abutments, including the type and extent of filters that could be used under the protective riprap layer, the size of the riprap, and the extent the riprap should be placed up an abutment slope, into the channel, and on the approach embankment; (2) flow-altering devices such as guide banks, dikes, spurs, bendway weirs and other in-channel devices, including the size, type, placement, and feasibility of using these devices; and (3) nontraditional abutment scour countermeasures such as articulated or tied mats and blocks including the size, type, placement, and feasibility of using these devices.

  • Supplemental Notes:
    • This project was initiated in July 2001 as NCHRP Project 24-18 with the University of Mississippi and with Dr. Brian Barkdoll as the principal investigator. Dr. Barkdoll left the faculty at the University of Mississippi in August 2002 to join the faculty at Michigan Technological University. The NCHRP oversight panel requested that the research remain with the original research team headed by Dr. Barkdoll. Therefore, at the completion of Phase I (August 2002), the contract with the University of Mississippi was terminated and Project 24-18 was closed-out. A contract to complete Phase II of the research was awarded to Michigan Technological University for $363,116 on August 29, 2003 with Dr. Barkdoll as the principal investigator. The research for Phase II of this project will be completed as NCHRP Project 24-18A.
