Catchment- and event-type specific synthetic design hydrographs : estimation, characterization, regionalization, and uncertainty

Abstract

Design flood estimates are needed in hydraulic design for the construction of dams and retention basins and in flood management for drawing hazard maps or modeling inundation areas. Traditionally, such design floods have been expressed in terms of peak discharge estimated in a univariate flood frequency analysis. However, design or flood management tasks involving storage, in addition to peak discharge, also require information on hydrograph vol- ume, duration, and shape. A bivariate flood frequency analysis allows the joint estimation of p Show more
