Revisiting flood peak distributions: A pan Canadian investigation
Original language description
Safe and cost effective design of infrastructures, such as dams, bridges, highways, often requires knowing the magnitude and frequency of peak floods. The Generalized Extreme Value distribution (GEV) prevailed in flood frequency analysis along with distributions comprising location, scale, and shape parameters. Here we explore alternative models and propose power type models, having one scale and two shape parameters. The Burr type III and XII distributions are compared against the GEV in 1088 streamflow records of annual peaks across Canada. A generic L moment algorithm is devised to fit the distributions, also applicable to distributions without analytical L moment expressions. The analysis shows: the models perform equally well when describing the observed annual peaks. The right tail appears heavier in the BrIII and BrXII models leading to larger streamflow predictions when compared to those of GEV.The GEV predicts upper streamflow limits in 39,1 per cent of the records. These limits have reali
