Building Better River Models: Integrating Bathymetry, GNSS, Total Stations & 3D Scanning

---

Join us for a technical deep dive into a complex bathymetry project on the Saint-Charles River near Drouin Bridge in Québec City. Our experts will discuss the project scope, field preparation, deployed technologies, and an integrated workflow that combines bathymetry, conventional surveying, and 3D scanning.

This session also highlights unexpected on-site challenges, such as a significant drop in water level, GNSS limitations under the bridge, and shallow areas, along with the strategies used to overcome them and deliver reliable results.

In this webinar, we will cover:

• Acquisition Strategy: Defining project scope using KMZ data and executing densified bathymetric cross-sections.
• Technology Integration: Survey preparation and deploying autonomous bathymetric systems alongside Trimble GNSS and total stations.
• Solving Field Challenges: Practical workarounds for a 6-foot water level drop, GNSS obstructions under the bridge, and overcoming manual measurement of shallow areas.
• 3D Scanning: Utilizing Trimble scanners for precise structural documentation.
• TBC & RealWorks Workflow: Data processing, including cleaning, registration, and classification of multi-source data.
• Final Deliverables: Producing accurate bathymetric surfaces, cross-sections, and drainage plans.
