This TWAP River Basins indicator data portal (2016) covers all of the world’s 286 transboundary river basins. It allows users to view results of around 15 key indicators and sub-indicators, for baseline assessment of the relative risks in these basins (2010), and projections to 2030 and 2050. Users can also create their own indices, based on any number of indicators and varying weights. Transboundary basin factsheets, GIS files of basin and basin unit boundaries, background data, and more are available for download from the portal.
