A multi-level approach to flood frequency regionalisation

A multi-level approach to flood frequency regionalisation

A multi-level approach to flood frequency regionalisation is given. Based on observed flood data, it combines physical and statistical criteria to cluster homogeneous groups in a geographical area. Seasonality analysis helps identify catchments with a common flood generation mechanism. Scale invaria...
