Measures water depth and maps submerged terrain using single-beam and multibeam sonar for rivers, lakes, reservoirs, channels, navigation routes, and other project areas.

Provides pre-dredge, progress, and post-dredge surveys to establish existing conditions, track work, and verify completed depths, elevations, and changes to the underwater surface.

Combines underwater sonar mapping with above-water laser scanning to develop coordinated 3D information for shorelines, bridges, dams, banks, navigation areas, and other built environments.

Maps submerged and partially submerged infrastructure such as bridge pilings, dam components, intakes, foundations, and related structures, including bed-condition and scour assessment.

Uses ROVs, side scan sonar, and imaging sonar to locate, inspect, and document underwater objects or structures where visibility, access, or working conditions are limited.

Uses sub-bottom profiling to investigate layers beneath the bed and core sampling to recover physical sediment for examination, characterization, or project-specific testing.
