基于非线性弥散关系的缓坡方程波浪传播变形模拟研究
Modeling of Wave Propagation and Transformation by the Mild?slope Equation with Nonlinear Dispersion
摘要
Abstract
Objective]As surface waves propagate from deep to shallow water,the nonlinearity of waves would be strengthened due to the effect of topography and various hydraulic struc-tures,which can't be descript well with the linear dispersion relations.The obj ective of this article is to investigate the effects of the nonlinear dispersion relation.[Methods]In the pa-per,we attempted to solve this problem by the mild?slope equation with nonlinear disper-sion,which will be used to simulate wave propagation and transformation on Berkhoff topog-raphy.[Results]The computational results between linear and nonlinear dispersion are pres-ented.The results of nonlinear dispersion agree with the actual measure data,which is better than that of the linear dispersion.[Conclusion]It illustrates that the nonlinear model is suit-able for studying the wave transformation with weak nonlinearity in offshore area.关键词
