Bathymetric & Hydrographic Surveying
Supporting engineers, consultants and authorities with precise underwater and hydrographic mapping.
Our hydrographic and river surveys provide the reliable data needed to manage waterways, protect infrastructure and support sustainable flood resilience safely and accurately.
Managing unstable banks, changing currents and limited access while maintaining absolute precision.
Riverbanks can be unstable, currents unpredictable, and access limited yet the accuracy of hydraulic data is critical to flood modelling, watercourse management and civil engineering design.
Traditional methods can be slow, unsafe and inconsistent. Today’s environmental, infrastructure and energy projects demand fast, high-resolution datasets captured with minimal disruption and maximum reliability.
Every measurement, level and coordinate influences the success of the final build. Accurate, coordinated survey data ensures that construction moves forward with confidence, allowing teams to:
Model with confidence
ensure flood risk assessments and hydraulic simulations are based on verified data.
Design safely
support bridge, culvert and weir design with accurate riverbed and bank profiles.
Monitor change
detect erosion, sedimentation or water level shifts over time.
Protect assets
inform maintenance and improvement works for waterways, reservoirs and drainage systems.
Reduce risk
improve safety and planning by understanding channel geometry and flow conditions.

Coastal & Marine Engineering Projects, River Surveys & Ports
We combine bathymetric, topographical and laser scanning data to create continuous 3D terrain models above and below the water.
Our use of USVs and UAVs keeps teams out of hazardous environments while improving coverage.
Specialists in confined-space, live-water, and flood-sensitive surveying.
Millimetre-accurate datasets ready for CAD, GIS and BIM environments.
Low-impact methods that support biodiversity and reduce carbon footprint through efficient workflows.
Technology That Delivers Precision
We use cutting-edge hardware and software to deliver robust hydrographic data, including:
- CHC Apache 4 USV – automated hydrographic survey vessel for safe, efficient channel mapping.
- CHC i93 GNSS + Controller – establishing control networks with centimetre accuracy.
- Trimble X7 Laser Scanner – for structural geometry and bridge asset capture.
- Integrated CAD & GIS processing – providing clients with models compatible with hydraulic and environmental simulation software.
Providing clients with accurate 3D models ready for hydrographic, environmental and civil engineering analysis.
From remote-controlled USVs to drone reconnaissance, our methods reduce site risk while maintaining full environmental compliance.
Our work contributes directly to sustainable water management, helping clients make informed decisions that protect habitats and mitigate flood impact.
