Water topography
- Digital Terrain Models of the watercourse (DTM-W)
- Cross-sectional and longitudinal profiles
- Substrate of the river bed
The autonomously operating measuring catamaran is equipped with a single beam sonar. In shallow waters, underwater cameras are used for optical measurements. The watercourse structure and its depth profile can thus be determined with high spatial resolution. The double-antenna RTK (real-time kinematics) operated GNSS system is coupled with an inertial measurement unit (IMU) and accurately records the position of each data point. The underwater cameras allow for an assessment of the subsoil composition.
Water quality monitoring
- Water temperature
- Oxygen content
- Oxygen saturation
- Turbidity
- Electrical conductivity
- pH value
- Redox potential
- Suspended solids
High-resolution depth-profiles of physical-chemical data can be recorded by lowering a mobile multi-parameter probe from the RiverBoat.
Surface scan with 360° camera
- Vegetation
- Riverbank structures
- Buildings
The 360° camera unit produces panoramic footage from anywhere on the watercourse, allowing for the objective recording of the environment. Dense 3D-point clouds are generated from these images for surveying and other purposes.
Hydraulics
- Flow velocity
- Discharge
A modular ADCP device flexibly performs velocity and discharge measurements along the entire water body.
