Monitoring Rubble-Mound Coastal Structures With Photogrammetry
Abstract
Monitoring coastal projects usually involves repeated surveys of coastal structures and/or beach profiles. When a coastal structure such as a jetty is protected with concrete armor units or quarrystone, monitoring the movement of individual units may be difficult, if not impossible, by conventional survey methods. Photogrammetric techniques, however, can be used to get precise measurements from properly acquired aerial photographs. When the structure is photographed at low tide, an accurate, permanent record of all visible armor units can be obtained, which record can then be analyzed or "surveyed" with stereoscopic photogrammetric compilation instruments to reveal any movement of the units.
