Extended Data Fig. 6: Sensitivity of results to the weights used for estimating distance D.
From: Megafloods in Europe can be anticipated from observations in hydrologically similar catchments
(a) Number and (b) fraction of megafloods larger than envelope for four weight combinations: equal weights (‘equal’, α = β = γ = 1), double weight for Area (‘wA’, α = 2), double weight for mean annual flood (‘wQm’, β = 2), double weight for CV (‘wCV’, γ = 2). (c) Average number of donor catchments for the four weight combinations. Colours indicate the five alternative regions of Extended Data Fig. 4a.
