Bowman project hydrogeologists evaluated the deepening of a quarry that was located immediately adjacent to the Hudson River with a floor 200-ft below the river. A field investigation was developed, and an analysis was performed to evaluate the potential to deepen the quarry by an additional 100-ft.

Bowman geologists were responsible for the implementation of a groundwater investigation relative to a proposed quarry deepening. The work consisted of drilling oversight and logging of approximately 1,000 LF of bedrock borings, installation of bedrock piezometers, stream gauging, photolineament analysis, aquifer testing, and geologic mapping.

Bowman evaluated visual impacts to Viewshed for Hooper Garnet Mine Expansion. A digital terrain model was used to create expansion footprint. Topographic mapping was used to predict visual impacts. Mitigation measures and reclamation planning were developed to reduce visual impacts to the community.

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.

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.

Our team performed a multi-disciplinary mapping and sediment characterization study for Bergmann Associates. The project located at lock C/S-1 at the northern end of Cayuga Lake entailed performing multi-beam echosounding, single beam echosounding, aerial UAV topographic mapping, GPS survey, utility location and sediment sampling.

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

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.

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.

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.
