Hydrographic surveys are technical studies carried out to map, measure and describe bodies of water, such as oceans, rivers, lakes and dams. These surveys provide essential data on depth, bottom relief, currents, tides and other physical and environmental characteristics of the waters.

Objectives of Hydrographic Surveys

Ensure navigation safety – Identify depths, submerged obstacles and navigable channels.
Support coastal and river engineering – Dredging projects, construction of ports and dams.
Monitor environmental changes – Analysis of coastal erosion, sedimentation and water quality.
Mapping water resources – Identifying aquifers and water supply sources.
Plan economic activities – Fishing, mineral exploration, tourism and energy generation.

Hydrographic Surveys we carry out:

Bathymetric Survey – Measures the depth and relief of the bottom of bodies of water (only in shallow depths)

Applications of Hydrographic Surveys

Navigation and Maritime Transport – Creation of nautical charts to guide ships and vessels.
Infrastructure Construction – Planning of ports, bridges and hydroelectric plants.
Environmental Management – ​​Pollution monitoring and conservation of aquatic ecosystems.
Exploration of Natural Resources – Identification of oil and gas deposits on the seabed.
Natural Disaster Prevention – Study of tsunamis, coastal erosion and floods.

Hydrographic surveys are essential for the security and sustainability of water resources.
