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).

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 ...
