Abstract: The early detection of deviations, problems and undesirable incidents is crucial for intervention during floods and other geohazard events. Dam and levee owners and responsible authorities must follow the development of such events from an early stage. Sharing of information is valuable for all involved. By inviting professionals and the public to contribute with observations, the number of observers within safety management increases. In Norway, a crowd-sourcing tool called regObs, gives the public and dam owners an easy way to report and share relevant observations. regObs can be used to contribute with observations within the pre-defined topics "water", "soil", "snow" and "ice". The tool is available on www.regobs.no and as mobile application. It uses an open data policy and everybody can register observations as well as see all observations. Observations are georeferenced, and follow a predefined form adapted to the specific topic. Pictures and notes can be added easily to the observations. The observations provide useful information during emergency actions and in the national flood, landslide and avalanche forecast services. The use of regObs are illustrated with examples and the advantages for dam and levee owners are highlighted.
