Precision Hydrometry: Level & Flow

Drone-based water-level measurement and non-contact surface-flow analysis for dynamic rivers and streams.

The technical edge

How it works

Drone-mounted radar altimetry delivers relative water levels to ~1 cm (sub-cm achievable in hover mode), while drone video supports surface-flow velocity analysis.

Strategic advantage

Why it changes the decision

Measures hydrological behavior without installing fixed equipment or placing personnel in moving water.
