New study indicates probable maximum rainfall modelling is out of date


 A new study says existing models for potential maximum rainfall are out of date and suggests existing dams are potentially at greater risk due to spillway inadequacy.

Researchers from UNSW and University of Melbourne say anybody who is planning to build a large dam needs to think 50 to 100 years ahead and consider the future impacts of climate change on the plausible upper limit of rainfall extremes.
