Project Highlights

Erie Canal Channel Multibeam Bathymetric Survey

Erie Canal, NY
Our team provided multibeam bathymetric scanning services to collect high density survey data below the water line on the Erie Canal in support of the Canal Corporation’s Navigation Information Program. Data was used to determine the nature of obstructions and detailed 3D images/maps of dredged areas.

Alcove and Basic Reservoirs

Albany, NY
The City of Albany requested that our team perform updated bathymetric, LiDAR and conventional surveys of Alcove and Basic Reservoirs – two of the three reservoirs that provide the City of Albany with drinking water. The results of these surveys would also provide accurate volumetric estimates and capacity tables for these reservoirs.

Seawall Stabilization

Troy, NY
Our team was hired to perform a combined multi-beam side scanning sonar and LiDAR investigation to produce 3-D digital model of the vertical surface of the Troy seawall above and below the water surface. This continuous model produced a high resolution “picture” of the wall.

Mohawk River Locks E8 to E7

Bergmann, NY
Bowman provided dual mapping data as part of the flood warning and optimization system in addition to maintenance and inspection contracts statewide. The team was contracted to provide bank-to-bank bathymetric mapping and simultaneous LiDAR data collection of the Mohawk River between Locks E8 and E7 to support flood modeling activities.

Champlain Lock Structures

New York
Our team provided combined multibeam bathymetric and laser scanning services to simultaneously collect high density survey data above and below water line, in support of the Canal Corporation’s structural inspection program.

Living Breakwaters

Staten Island, NY
Partnered with Weeks Marine, our team provided multiple roles and services for this project. We acted as the geologist of record and provides construction material inspection and oversite services at the breakwater materials extraction source (Carver Johnstown Quarry).
