(waves, tides, currents), sedimentation (erosion, accretion), and/or structural elements of the
projects were monitored to determine if they were performing as designed. Most of these
projects were monitored intensely over an extended period of time.

One work unit in the MCNP Program, "Periodic Inspections," entails monitoring projects on a
periodic basis. Projects are monitored at a low level periodically to add to the Corps'
understanding of the long-term response of a particular structural design to its environment.
Structures are generally monitored through low-cost remote sensing methodology
(photogrammetry). Base level data are initially obtained and the projects are revisited
periodically to determine changes that may have occurred. Sites monitored through periodic
inspections are shown in Figure 2.
