Affiliated Researchers was subcontracted to provide its bathymetric and topographic surveying services at an inland lake in support of a Comprehensive Long‐term Environmental Action Navy (CLEAN) 9000 contract for the Naval Facilities Engineering Command (NAVFAC).

Our surveying services were needed in order to refine the conceptual site model, towards future investigations and action planning.

Affiliated Researchers provided bathymetric surveying using both single-beam hydrographic techniques and conventional RTK-GPS techniques, in order to obtain survey data of the baseline conditions of the lake.

To provide bathymetric surveying of the project area, Affiliated Researchers’ hydrographic surveying team utilized a dual-frequency single-beam echo-sounder system, RTK-GPS survey equipment, and hydrographic software.

In areas of shallow water, as well as areas of excessive debris and vegetation where echo-sounder technology was not usable, Affiliated Researchers conducted the bathymetric surveying using conventional RTK-GPS techniques.

Affiliated Researchers also conducted topographic surveying along the shoreline of the project site utilizing conventional RTK-GPS techniques to confirm topography along the shoreline to enable a seamless joining of the bathymetry with the topography.

Affiliated Researchers compiled the bathymetric survey data with the topographic survey data to provide for a complete, seamless deliverable.

Specializing in environmental mapping, reporting, and technology since 1990, Affiliated Researchers has providing its high-quality environmental and technical services throughout the US.  Please contact our office to discuss your project.
