Commonly applied are flood frequency Received 16 July 2018 analyses and design storm approaches, while the derived flood frequency using continuous simulation has Accepted 22 January 2019 been getting more attention recently. In this study, a continuous hydrological modelling approach on an EDITOR k hourly time scale, driven by a multi-site weather generator in combination with a -nearest neighbour A. Castellarin resampling procedure, based on the method of fragments, is applied. The derived 100-year flood estimates in 16 catchments in Vorarlberg (Austria) are compared to (a) the flood frequency analysis based on observed ASSOICIATE EDITOR discharges, and (b) a design storm approach.
