About ARR Data Hub
The ARR Data Hub serves the design inputs that Australian Rainfall & Runoff 2019 requires for every flood estimate: regional losses, temporal pattern ensembles, preburst rainfall, areal reduction factors and interim climate-change guidance, all keyed to your catchment location and downloadable in machine-readable form. Design rainfall depths themselves come from the Bureau of Meteorology's 2016 IFDs, which the Hub links alongside.
Australian flood practice effectively cannot proceed without it — every RORB, WBNM, URBS or TUFLOW study starts by pulling a Data Hub extract, and most local tooling parses its text format directly.
