Abstract :
In order to describe the dependence structure of the two relief factors of debris flow of main channel length and drainage height difference, this paper provides an ordinal sum of a class of Copulas, such that its concordance measures of Kendall´s τ and Spearman´s ρ being suitable for the data. The parameters in Copulas are calculated to get some specific Copulas, which can be better fitting to the dependence structure of the two relief factors.
