Abstract: The peaks over threshold method (POT method) is an alternative to the block-maxima method for estimating return levels (these are the levels that are exceeded by a daily precipitation, resp. by a daily average discharge, only with a given small probability; in statistical language they are called high quantiles) when the studied series are not long enough. The paper compares both methods for precipitation and discharges series of Northern Moravia. It is shown how to overcome problems in the POT method caused by autocorrelation and seasonality. |
