Methodology for indicator calculation

The WEI+ is an advanced version of the WEI. It is geo-referenced and developed for use on a seasonal scale. It also takes into account water abstraction (gross) and return (net abstraction) to reflect water consumption.

      Thank you for the comment. Given the text adjustments based on the indicator definition, we will re-consider to provide more background on the development from WEI to WEI+

      Specify the difference between WEI and WEI+.

    Hungary:
    A question to be considered is whether it would be useful to provide a separate WEI+ index for surface and groundwater. In the case of Hungary, the use of water from underground water can significantly reduce the base yield of surface water, especially in the dry summer period.

      Thank you for you comment, we are aware on current developments to elaborate SW and GW WEI+ indicators separately. However, the WISE SoE database is not sufficiently capable to compute the WEI+ for GW and SW seperately and thus for the moment this is not planned.
