Water Resources Sector
How much the reservoir holds today, and how the dam is behaving
We measure the reservoir bed with bathymetry from uncrewed surface vessels (USV), and the dam with GNSS, surveying and geotechnical instruments. You receive an updated area-volume curve and a deformation series for the structure.
Every flood season leaves sediment in the reservoir, and the area-volume curve from the original design stops matching what the reservoir actually holds. Our airborne LiDAR stops at the water surface, so we merge the bathymetry of the bed with LiDAR of the banks into a single topo-bathymetric model.
Outside the reservoir, we model rivers and streams for flood studies, check canal gradients, scan intakes and treatment plants for the As-Built, and delineate riverbank and lakeshore buffer strips.

Where we work in water resources
Dams and reservoirs
Bathymetry, area-volume curves and deformation monitoring of the structure.
Hydroelectric plants
Surveys and 3D models of intakes, conveyance works and powerhouses.
Canals and irrigation systems
Mobile mapping of the network, gradient checks and infrastructure inventory.
Rivers and river basins
Channel and floodplain modeling, and tracking of how the river channel shifts.
Treatment plants and networks
3D laser scanning, As-Built BIM models and pipe network mapping.
Riverbank protection and drainage
Topo-bathymetric surveys, and tracking of erosion and sedimentation.
Four business lines, from planning to monitoring
Plan, design, build, operate and monitor. The same four lines in every sector, with the activities and deliverables that sector needs.
