Capabilities
Breakwater Surveys
Offshore breakwaters are designed to absorb the energy of waves and reduce the intensity of wave action in inshore waters. However, large storms can cause waves to overtop the breakwater and cause sediment transport and erosion. TerraSond is often called upon to conduct topographic and bathymetric surveys of breakwaters to identify and map where there is shoaling, erosion, breaks and displacement of rock along the breakwater. Survey limits for these surveys can also include the below water portions of the breakwater.
