12d’s resident Water Resources Engineer, Rob Graham presented a very popular webinar on ARR 2016…
ARR 2016 (Australian Rainfall and Runoff) has updated its hydrology for an ever-changing environment, and 12d Model is ready for the change!
For ARR 2016, the new rainfall intensities and patterns are downloaded into 12d Model from the Australian Bureau of Meteorology (BOM) and the ARR Data Hub. Also for ARR 2016 there are new zones and now ten rainfall patterns for each storm duration instead of the one rainfall pattern used in ARR 1987.
Critical storm no longer means maximum!
