 Citizen science is the involvement of the general public in scientific research, data collection, and analysis. In the field of hydrology, this can involve collecting data using sensors or other technologies, which can be used to supplement existing data sets. Citizen science can also provide valuable insights into local processes and help to identify areas where traditional monitoring networks may not be able to reach. Additionally, citizen science can be used to generate new knowledge about hydrological systems, which can then be used to inform decisions related to water resource management.
