A hydrographic/bathymetric survey is the process of measuring and mapping underwater features to determine the topography of a water body's bed. This type of survey involves collecting data on the depth, shape, and physical features of the seafloor or riverbed, as well as identifying potential obstructions, such as rocks or wrecks.
Hydrographic surveys are essential for various applications, including:
Nautical charting: Ensuring safe navigation for ships and vessels by creating accurate charts that show water depths and potential hazards.
Maritime construction: Assisting in the design and construction of marine structures like harbors, bridges, and offshore platforms.
Dredging operations: Supporting dredging projects by mapping areas that need sediment removal to maintain waterway depth.
Environmental studies: Monitoring underwater ecosystems and changes in the seabed for environmental assessments.
Flood management: Providing data for modeling and managing water flow in rivers and coastal areas.
