CrowdWater is a hydrological citizen science project. Citizen scientists collect hydrological data in the categories water level, temporary streams, soil moisture and plastic pollution, using the CrowdWater | SPOTTERON app. There is no need for measurement devices and thanks to the intuitive design, everyone interested in water and citizen science can participate. It is possible to initiate measurement sites all over the world and every citizen scientist can upload updates. Furthermore, the data quality is controlled by citizen scientists playing the CrowdWater game online. The game is also helpful for new citizen scientists that want to get a first impression of the project.
CrowdWater stands for an independent and reliable data collection by citizens for modelling of floods and droughts and as a supplement to existing measurements. The method is developed scientifically by the University of Zurich such that it can be applied in remote regions and in developing countries.
