Single Beam Surveys
Single beam data are used to generate cross sections in rivers and channels and to generate slope profiles. Single beam hydrography is an economical option for general bathymetric characterization, but is not the best choice for detecting and describing bottom features (see Multibeam Surveys).

Representative Projects
Beach Profiling: Coastal New Jersey
OSI has supported various U.S. Army Corps of Engineers Districts' coastal engineering missions since 1994 with beach profiling surveys. In the vicinity of Ocean City, New Jersey, three-dimensional data were acquired using a combination of topographic, mini sea-sled, and automated ...
Charting Navigable Waters
Ocean Surveys was a subcontractor to the prime on NOAA’s very first contracted hydrographic survey. Since 1999, OSI has acted as a prime contractor and surveyed thousands of square nautical miles of navigable waters on behalf of NOAA (see table ...
Reservoir Safe Yield Analysis: Lynchburg, Virginia
To support a reservoir siltation analysis of the Pedlar Reservoir, Ocean Surveys performed a detailed hydrographic survey and calculated the existing capacity. Following completion of the survey, a Digital Terrain Model (DTM) of the reservoir bottom surface was created and ...
Wastewater Treatment and Disposal: Alexandria, Egypt
The wastewater treatment and disposal facilities serving the City of Alexandria, Egypt were being modernized and upgraded. Feasibility studies required thorough evaluation of wastewater disposal alternatives, including an ocean outfall. To support that evaluation, OSI conducted a multi-disciplinary survey program ...
