Repair, Evaluation, Maintenance, and Rehabilitation Research Program: Case Histories of Corps Breakwater and Jetty Structures. Report 8. Lower Mississippi Valley Division

Abstract

This report is eighth in a series of case histories of US Army Corps of Engineers (Corps) breakwater and jetty structures at nine Corps divisions. Herein, case histories are presented for 10 jetty structures located within the US Army Engineer Division, Lower Mississippi Valley (LMVD), which encompasses the gulf coast of Louisiana. Presently, there are approximately over 153,000 lin ft of jetty structures managed by LMVD. These structures are predominantly of rubble-mound construction. Seven of the projects have undergone repair and/or modification during their lifetimes. Most of this work has consisted of placing additional stone to bring structures up to grade. Subsidence of structures, due mainly to unconsolidated silts and clays of the underlying foundation, appears to be the principal cause of deterioration. In particular, the jetties at Southwest Pass have a very extensive repair history.
