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 waste water discharges. The data set should be used in conjunction with the HYDRO Catchments layer to display contributing areas to each flow node. Data results include naturalised flow percentiles (NATQ1-99%), naturalised mean monthly flows (NATMMF1-12) and physical catchment descriptors. Flow estimates are provided in m3/second. To provide naturalised flow estimates for Irish rivers that will enable assessment of quantitative impacts relating to hydrological alterations.

A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum.
