Our hydrographic surveys plot a detailed plan of all features of a project below the water surface, assisting with Flood Risk Assessments and hydraulic modelling. By hydrographic surveying the watercourse we can measure precise sections, defining soft bed levels, hard bed levels, embankment levels and elevations to key structures that may pass over.
What is a hydrographic survey?
A hydrographic survey determines the physical features of an underwater area. Much like land surveys, a hydrographic survey requires very specialist equipment and provides essential information for construction teams working on water-based or water-adjacent projects.
What can a hydrographic survey be used for?
Hydrographic survey services are essential on construction projects such as docks and marina builds and waterway development. They are also used on specialist projects such as wreck location, dredging and diversion of water sources.
While establishing water depth is one of the most important aspects in hydrographic surveying, understanding the location of hidden obstacles such as irregular soil deposits, reefs and man-made objects is also key.
Why should I use a hydrographic survey?
Failing to map construction sites on land opens architects, designers and construction teams up to several risks. Underwater projects are no different. For example, without an understanding of water depth, it would not be possible to safely say what size of ship could travers a canal or dock safely.
Hydrographic surveys can also be used after a project is complete as a way to double check water levels or perhaps to judge the effectiveness of services carried out, such as dredging.
With offices in London, Newcastle, Nottingham and Edinburgh, we are able to provide hydrographic surveys to the whole UK. No matter what sector you’re in, small business or large PLC, our trained specialists are here to help, working only to the very highest standards.
