Aqueduct Water Risk Atlas 4.0
Hydrological modelling of water risk at sub-basin level: baseline water stress, water depletion, interannual and seasonal variability, groundwater table decline, riverine and coastal flood risk, drought risk and untreated connected wastewater. Aggregated to country and province level for reporting.

Notes
Aqueduct outputs are modelled indicators, not measurements. Water stress in particular is a ratio of withdrawal to available supply and is highly sensitive to basin definition, so Hydrionis stores it with basis "modelled" and surfaces the sub-basin caveat on every ranking.
