Citizen Science on Water Resources Monitoring in the Nhue River, Vietnam

The explosion of citizen science (CS) in data collecting, including hydrology and water resources management, results from information and communication technology development. This approach is still a new topic in Vietnam, while CS development stages are not popular in the previous works. This paper demonstrates how a CS project can be developed, a pilot area at Lien Mac 2 sluice, Noi Bridge, and Dong Bong 1 pumping station on the Nhue River, Vietnam. There are seven main stages to implement a CS project, in which monitosring observation choose is a crucial factor to attract participants and obtain long- recorded observations. Social network and smartphone are a tool to boost CS development and the young generation is interested in this approach. Citizen-based water level monitoring was conducted by images that will be uploaded on social networks. The water levels obtained from the CS on the Nhue River are as good as the conventional approach. The step-by-step CS approach can be applied in other aspects of water resources management such as land use, water quality monitoring to promote the CS development.
