Comparison between characteristics of mild slope equations and Boussinesq equations

Boussinesq-type equations and mild-slope equations are compared in terms of their basic forms and characteristics.It is concluded that linear mild-slope equations on dispersion relation are better than non-linear Boussinesq equations.In addition,Berkhoff experiments are computed and compared by the two models,and agreement between model results and available experimental data is found to be quite reasonable,which demonstrates the two models' capacity to simulate wave transformation.However they can deal with different physical processes respectively,and they have their own characteristics.
