This dataset provides estimates of naturalised river flow duration percentiles for rivers across Ireland. The flow estimates represent expected river flows under naturalised conditions, excluding artificial influences such as water supply abstractions, discharges, or other human interventions that could alter natural flow patterns. Published via Ireland's open data portal, the dataset supports hydrological analysis by offering a baseline understanding of river flow behaviour absent anthropogenic modification. It can be used to assess flow variability, compare rivers, and inform water resource management, environmental studies, and hydrological modelling across the national river network.This data set contains estimates of naturalised river flow duration percentiles for Irish rivers. The flow estimates represent flows that could be expected in rivers under naturalised conditions and do not take account of artificial influences of any kind such as water supply abstractions or wast...
