Hydrographic Surveys
Sedimentation Volumes & Dredging Analysis
Comparing periodic surveys to quantify sedimentation and dredging volumes.
Through periodic hydrographic surveys we build bed surface models at different points in time, then perform precise volumetric comparison to quantify accumulated sediment or material removed by dredging.
These outputs are essential for monitoring contractors and for quantity-based payment certificates.
Key features
Time-series volumetric comparison
Before/after accuracy suitable for quantity certification.
Colour difference maps
Visualising deposition and erosion zones.
