A global analysis of rainfall and rivers by UNSW engineers has discovered a growing pattern of intense flooding in urban areas coupled with drier soils in rural and farming areas.

A rise in global temperatures of 2 degrees Celsius is likely to bring more extreme rainstorms to many parts of Australia even as other areas experience severe droughts, new research shows.

Cities face harsher, more concentrated rainfall as climate change not only intensifies storms, but draws them into narrower bands of more intense downpours, UNSW engineers have found.

Thirty-year weather records from 79 locations across Australia reveal peak downpours during storms are intensifying at warmer temperatures, leading to greater flash flood risks.

Dangerous flooding in a future warmer climate may be greater than forecast because of changes to the distribution of rainfall within storms, writes Ashish Sharma and Conrad Wasko.
