L-MOMENTS AND THEIR USE IN MAXIMUM DISCHARGES’ ANALYSIS IN CURVATURE CARPATHIANS REGION
L. ZAHARIA
ABSTRACT. – L-moments and their use in maximum discharges’ analysis in Curvature Carpathians region. This paper aims to present L-moments statistics and their application in analysis of annual maximum discharges series in Curvature Carpathians region, in order: 1) to determine the discordance measure and 2) to identify the regional theoretical distributions most appropriate to the data series in the studied region. The analysis performed allowed: 1) to determine two gauging stations (Mirceşti on Putna River and Moara Domnească on Teleajen River), whose data are discordant comparing with those from the other 41 analyzed stations and 2) to identify three theoretical distributions best fitting maximum annual discharges series: exponential, generalised Pareto and Pearson type 3 distributions.
Keywords: L-moments, probability distribution, discordance, maximum discharge, Curvature Carpathian Region.
