Shoreline & Inter-tidal Topographic Survey:

Surveys of intertidal areas are required for a number of reasons.  For example beach surveys may be required to measure quantities and rates of erosion / deposition. Hydrodynamic models require that elevation data is available to a level above that of the high tide.

Topographic survey methods using GPS equipment are used to survey that part of the intertidal areas which cannot be surveyed by bathymetric methods.
