Rivers, Streams & Floodplains

Accurate river-corridor terrain, from the floodplain through the banks to the channel bed, built for hydraulic modelling, planning and long-term monitoring.

Dense riparian vegetation hides the ground, banks shift after every flood, and the channel bed is invisible to conventional aerial survey. Gaps between land and water data undermine flood models.

Drone LiDAR reaches the bare earth beneath vegetation; sonar or green-wave LiDAR adds the channel bed; RTK control and repeat flights tie every campaign to the same reference.

Ground classification, merged topo-bathymetric surfaces, cross-sections and change detection quantify erosion, deposition, bank retreat and vegetation change between floods.

Drainage authorities and planners get one continuous, model-ready surface and measurable evidence for maintenance, restoration and flood-risk decisions.
