Study on extension method of series models in bed erosion prediction

Aiming at comprehensive analysis of scour around a structure on seabed by extension method of series models,two new opinions were proposed in this paper.Firstly,each model of series models should satisfy the related similarity criteria.Secondly,the independent variable can be both single variable and multi-factor parameters.Extension equations of series models,extension equations of series models in bed erosion prediction and extension equations of series models with multi-factor parameters were derived.This paper considers that this method is only used to reduce the influence of scale so as to obtain more objective conclusions,but not to analyze the relationship between principal variables and independent variables.The relation between utmost bed erosion value and its related factors is quite complex.
