With a deep understanding of the challenges of surveying underwater environments and their environs, 360 Surveys offer unparalleled experience and efficiency. We are specialists in inshore and near-shore hydrographic surveys from inland waterways to rivers, lakes, and coastal surveys.

Our Approach

360 Surveys delivers high-quality hydrographic surveys through a combination of our people, process, and technology. Hydrographic surveying is generally carried out in challenging environments and safety is core in all our field workflows and processes.
To support our experienced surveyors, we source for a wide range of specialist equipment such as boats, jet canoes, hovercraft, echo sounders, tide gauges, sonar scanners, magnetometers, laser scanners, remote sensing, and integrated UAV / drone technology. These tools, when operated by our experienced professionals, enable the delivery of highly accurate, fast, and cost-effective hydrographic surveys. We are specialists in inshore and near-shore hydrographic surveys from inland waterways to coastal surveys of any scale.

A good hydraulic model relies heavily on the data inputs used to build the model, particularly the existing bathymetry of the watercourse and the topography of its banks and surroundings. Therefore accurate, verified survey data is a key element of a reliable hydraulic model which then enables the planning and design of flood defense measures where necessary. Consequently, the certainty provided by a reliable model can maximize the return on investment in the planning of flood management programs.

Our near-shore and coastal surveys help our clients understand the changes in bed levels next to key shipping and harbor channels, and to predict the severity of coastal erosion. The data we generate is used to monitor changes along our coasts which are constantly in flux. Our data is used to plan coastal defense barriers or plan dredging operations, ensuring that our key harbor infrastructure remains operational.
As the world adjusts and adapts to the challenges of climate change, accurate hydraulic modeling of our watercourses is critical to predicting the behavior of rivers during heavy or prolonged rainfall events. The hydrographic survey teams at 360 Surveys have established efficient and effective workflows to deliver verified geospatial data from the field and process it for use in all commercial floods modeling software.
