Flood damage can be minimised by ensuring optimum capacity to drainage structures. An underdesign of these structures increases flood damage cost whereas an overdesign incurs unnecessary expenses. The optimum design of water infrastructures depends largely on reliable estimation of design floods which is a flood discharge associated with a given annual exceedance probability. For design flood e...

Regional flood frequency analysis (RFFA) involves transfer of flood characteristics from gauged to ungauged catchments. In Australia, RFFA methods generally focus on the application of empirical methods based on linear forms of model such as the Probabilistic Rational Method, the Index Flood Method and the regression-based techniques. There have been successful applications of non-linear models...

Regional flood frequency analysis (RFFA) is a powerful method for interrogating hydrological series since it combines observational time from several sites within region to estimate risk-relevant statistical parameters with higher accuracy than single-site series. Since RFFA extreme value estimates depend on the shape of selected distribution data-generating stochastic process, there need suita...
