Abstract To deal with water stress, there is a need to compare the water management
issues
of hydrological regions in
order to inter-compare them and transfer knowledge from one area to another. An
approach is presented using case-based reasoning (CBR) to inter-compare
European drainage sub-basins. The CBR uses indicators for the natural
hydrological potential of drainage sub-basins, the types of water stresses and
the mitigation measures to cope with this stress. A prerequisite for the success of this tool is that the indicators are publicly and digitally available for
the whole of Europe and contain insight to the appropriate information scale. This sets strong
limits to the indicators used. In some cases, a proxy indicator may be more
appropriate than a primary indicator, when these are not publicly available at
the appropriate information scale. The set-up of the CBR is illustrated using
some examples of indicators.
