Impacts of climate change on water bodies
- warmer temperatures
- increased evaporation
- changes in precipitation
Direct consequences for us in Germany as well
- Change in water temperature
- Falling groundwater levels
- Changed runoff dynamics
- Low water
- At the same time, more frequent occurrence of floods and heavy rains
Water bodies in Baden-Württemberg
Monitoring as a solution approach
What does monitoring mean?
- Long-term recording of various properties of a water body.
Examples of parameters to be recorded: Water quantity, hydraulic conditions (e.g. minimum water depths), water quality (oxygen, nutrients, ...)
Advantages and opportunities:
- Showing long-term correlations and changes
- Enables forecasts
→ Timely response to extreme events
→ Development of new adaptation strategies, early warning systems etc.
Participatory role of climate detectives - water monitoring by means of apps
EyeOnWater app (https://www.eyeonwater.org)
- Measurement of water quality of natural waters with the help of water color
- Water color provides information on the content of algae and organic substances
- Forel-Ule scale → Color scale used to determine the color of a body of water
- Measurements and data are made publicly available on the EyeOnWater website
Use of the EyeOnWater app (detailed in the guide)
- Take a photo of the water surface of the body of water.
- Assign the color of the photo to the given color scale.
- Enter other parameters.
- Send data.
CrowdWater app (https://crowdwater.ch)
- CrowdWater app collects data from a wide range of categories:
- Water Level (physical and virtual gauges), Soil Moisture, Dynamics of Drying Streams, and Plastic Pollution.
- CrowdWater consists of an app and website designed to collect data and measure water quality of natural water bodies.
- By specifying the location, data can be collected and compared over and over again at the same site.
Use of the CrowdWater app (detailed in the guide)
- Select the desired category (e.g. soil moisture) and create a new spot.
- Enter additional parameters, e.g. wet, dry, moist.
- Enter location description.
Why do we want to collect data using the apps in ParKli?
- We need a good database on the current state of our local environment.
- Together with you, we would like to go in search of clues and use the CrowdWater app and EyeOnWater app to collect data on the state of local waters.
- This data basis should make it possible to jointly develop and actively implement local measures for adaptation to climate impacts.
