Bathymetric and topographic surveys are two types of surveys conducted to map and understand the characteristics of the Earth's surface, either underwater or on land. While both surveys involve mapping the terrain, they differ in terms of the environment they focus on.AMI Consulting Engineers (AMI) has the unique tools and capabilities to use collected data to provide coastal and riverine engineering and analysis.

We are a full-service hydrographic surveying firm with more than 20 years of experience in high-quality hydrographic surveys. AMI’s client list includes government and private agencies, federal, state, and local governments. We have completed projects for the Army Corps of Engineers, National Park Service, U.S. Coast Guard, and various state DOTs, EPAs, and DNRs.

AMI provides the highest quality data collection that includes integration between hydrographic and topographic data. We have tools to incorporate high-definition side scan, sector scanning and other specialty imaging services of shoreline that can be overlaid onto the hydrographic data for a complete picture of the project’s environment. We use this data for applications such as:

Coastal and Port Infrastructure: Hydrographic surveys aid in the design and construction of coastal structures such as ports, harbors, breakwaters, and jetties. By accurately assessing the seabed topography, sedimentation patterns, and wave conditions, our team can optimize the layout and dimensions of these structures for efficient navigation, enhanced safety, and improved coastal resilience.

Dredging and Sediment Management: Hydrographic surveys provide crucial information for dredging operations and sediment management. By mapping areas of sediment deposition, our team can plan and execute dredging activities to maintain waterway depths, prevent siltation, and ensure optimal navigability.

Environmental and Marine Research: Hydrographic surveys support environmental and marine research efforts by providing valuable data on underwater ecosystems, habitat mapping, and the impact of human activities on marine environments. This information aids in developing effective conservation strategies and evaluating the environmental impacts of projects.
