Overall, annually reported data are available for water abstraction by source (surface water and groundwater) and water abstraction by sector with temporal and spatial gaps. Gap-filling methods are applied to obtain harmonised time series.

    We would like to point out that Portugal does not have water abstraction data available on an annual basis, but in accordance with the WFD planning cycles. Therefore, the values reported annually for Portugal are the same between planning cycles. So this values are not known to us.

      Thank you for your comment. Data for computing the WEI+ are mainly reported as annual under the WISE SoE and Eurostat dataflows. As mentioned earlier, in order to obtain a harmonized baseline on monthly resolution across all data required for WEI+ computation, we implement a disaggregation method by employing the surrogate data/coefficients. We acknowledge that that may cause some uncertainties particularly in those cases where no sufficient data are available. In that context, we had to perform large data gap filling exercise for Portuguese case. We kindly ask you about the next steps to be taken. We would happily replace the EEA computation with your results for WEI+ in the case that is available. If you have spotted large inconsistencies of WEI+ results in some certain river basins with the EEA calculation, with the potential baseline you would provide, we can explore how to improve the WEI+ results for Portuguese basins. Another option would be omitting that basin(s) from the final dataset and the map.

    The methodology is not very detailed, although there are additional elements in several other documents. It seems to me that there are at least two types of calculations concerning abstractions for the local level (sub-basins), (based on demand modelling?) and the national level (based on the national report?) but is there any harmonisation between these methodologies and if so, at what level?
