Bathymetric Surveys

Bathymetric Surveys are surveys that show depths and terrain configurations of the bottoms of water bodies. Bathymetric Surveys can be used for hydrographic mapping. For example, engineers use them for planning and monitoring harbor and river dredging operations, and to ascertain reservoir capacities for flood control and water supply systems. Furthermore, Bathymetric Surveys are used to build docks, determine water depth over a certain area, for cross sections through a water channel, or to monitor erosion along beaches and coast lines. Bathymetric surveys are usually referenced to local tidal or a vertical datum.
