The system
What is installed at the Backhausteich.
Biological processes
More oxygen supports aerobic microorganisms and natural degradation processes.
Food webs
More stable oxygen conditions help fish habitats, zooplankton and benthic organisms.
High and low water
GNSS-based water level information for the situational picture, dry spells and flood events.
Resilient communication
Zigbee point-to-point links for robust data transmission even without conventional infrastructure.
On site
The installation in the water body.
Images from the installation: delivery along the shore path, placing the station in the water by crane and laying the aeration line from the work pontoon.
Background
Why oxygen matters.
Oxygen is the currency of a water body: it decides which processes run and which organisms can survive. Active aeration is a supporting measure here, not a substitute for remedying the causes.
Microorganisms
Oxygen supports aerobic microorganisms and the breakdown of organic loads.
Fauna and food web
Better oxygen conditions can stabilise living conditions for fish, zooplankton and benthic organisms.
Resilience
Active aeration can help to ease periods of stress in impaired water bodies.
Pilot benefits
What the pilot at the Backhausteich shows.
- permanently laid aeration line instead of injection at a single point
- continuous oxygen input as a supporting measure
- GNSS water level information for high and low water
- Zigbee point-to-point communication that works without mobile coverage
Partners and support
Hands-on water-body expertise, space applications and robust data links.
The pilot is taking shape in collaboration with bioversum Jagdschloss Kranichstein, ESA Space Solutions and Drausy.
Focus on benefits
Active water-body aeration, water level information and robust communication for more resilient waters.
Context
Where WAMO Active fits into the network.
Monitoring shows the condition, and WAMO Active intervenes: the pilot combines the measurement technology of the WAMO family with a measure in the water body itself. How the two belong together – from analysis through aeration to verification of impact – is set out in the product overview and in the focus area on water-body restoration.
