A Comparison of the Uncertainty of Parameter Estimation Methods Using Annual Extreme Precipitation in the Taihu Basin of China

摘要

The potential damage caused by coastal flooding is increasing due tornsea-level rise and coastal development. Flood control planning is ofrngreater importance in coastal areas. In this paper, annual extremernprecipitation in the Taihu Basin of China was used to investigate therndifference between two commonly used parameter estimation methods,rnthe method of Conventional Moments (CM) and the method of Lmomentsrn(LM). Generalized Extreme Value (GEV) distribution wasrnused to describe the extreme rainfall events. The robustness andrnunbiasedness of the two parameter estimation methods were evaluated.rnMonte Carlo simulation was applied to compute the confidence boundsrnquantifying the uncertainty resulting from the use of these two methods.
