Before being published on line, all data will be sent to the Hydrological Adviser of the concerned country in order to authenticate them.

In cases where there are several organizations responsible for different networks, the Hydrological Adviser should fill a set of responses for his/her service and distribute one questionnaire to each of the other Services managing observational networks for hydrological purposes. Each of these Services would fill the Preliminary Information sheet, plus those sheets covering parameters they are responsible for.

In those cases where it is not possible to obtain responses from all the other services, the Hydrological Adviser should give an estimate of percentages of coverage of the data he is providing, something like: "data from country xyz, precipitation info covering an approximate 65% of the network, groundwater 30%, water quality not included."
This would also be the case in situations where the NHS is highly regionalized, and the inventory is complete for only one or a few regions.
