[Protection of the environment, protection of health. Note 2--Monitoring of flood environments: comparison of the results of the different methods and hygienic evaluations].

The authors take into consideration the results obtained from the application of the different methods and systems of river monitoring (E.B.I, Law 152/99, I.F.F), and they evaluate the agreement of the final judgment. The comparative analysis is conducted pointing out the conceptual and methodological differences of the three systems of the river monitoring. A good agreement of judgement arises from the correlation.
