Summary: Floods cause one third of all natural disasters worldwide, more than half the fatalities and one-third the economic loss. Accurate design flood estimation can help alleviate this impact. The estimation procedure currently used assumes that a given rainfall leads to a corresponding design flood, negating the influence variations in pre-existing soil moisture conditions may have. An alternative that overcomes the above limitation is to use stochastically generated rainfall series to simulate flows from which the design flood can be estimated. This study aims to develop a generic framework for stochastic generation of rainfall for design flood estimation in Australia.
