Climate regimes and yearly streamflow frequency analysis in Sicily

2008

Yearly streamflow frequency analysis is performed in Sicily, Mediterranean’s largest island, using the index flow procedure, i.e. fitting a single probability distribution function (pdf) to the available yearly flow data scaled by their mean. This requires 1) the identification of homogeneous regions where L-moments’ observed variability can be ascribed to sample variability only, and 2) the estimation of mean annual streamflow by multiple regression analysis with some significant climatic and morphologic covariates. Rather than having defined geographical boundaries, the identified homogeneous regions should gather basins sharing similar morphologic and climatic features. Steps 1) and 2) a…
