| Abstract | information on the long-term structural performance of selected stone-armored navigation structures to their environment. Coastal structures at St. Paul Harbor, AK, and Burns Harbor, IN, are discussed herein. The response of concrete-armored coastal structures to their environment will be presented in a subsequent CHETN. OVERVIEW: In the “Periodic Inspections ” work unit of the Monitoring Completed Navigation Projects (MCNP) Program, selected coastal navigation structures are periodically monitored to gain an understanding of their long-term structural response. Periodic data sets are evaluated to improve knowledge in design, construction, and maintenance of both existing and proposed coastal navigation projects, and will help avoid repeating past designs that have failed and/or resulted in high maintenance costs. Relatively low-cost remote sensing tools and techniques, with limited ground truthing surveys, are the primary inspection tools used in the periodic monitoring efforts. Most periodic inspections consist of capturing above-water conditions of the structures at periodic intervals using high-resolution aerial photography. Structural changes (primary armor unit movement) are quantified through photogrammetric techniques. When a coastal structure is photographed at low tide, an accurate permanent record of all visible armor units is obtained. Through the use of |
