Trend Estimation Of Hydrological Time Series In Southern Italy
Authors : Ferrari Ennio .
Abstract
Abstract This paper shows some preliminary results obtained from trend detection analysis of rainfall data aggregated at different time scales. The rainfall measurements refer to a set of 26 rain gauges distributed in a typical catchment of Southern Italy. Particularly the analysis concerns the Mann-Kendall non-parametric test to detect trends of both monthly and annual rainfall time series in two overlapping time periods. Finally the procedure has also been used for trend detection of the annual maximum of hourly rainfall observed at Crati basin and over the whole Calabria region.
