Collect data, control data
Using the CrowdWater app (available for iOS and Android), you can collect hydrological data in different categories all over the world. In the online CrowdWater game you compare the uploads from the category “virtual staff gauge” and help with controling and improving the data quality.
You can login here to get to your spots or to enter a new observation via browser. If this is the first time you contribute to the CrowdWater project, you can create an account on this site.
These things do also work in the CrowdWater app for iOS (on the left) and Android (on the right).
