Dataset description

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 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.

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.

Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.

Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.

Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
