摘要
将小波配置方法和精细积分方法相结合,提出了一种对水土侵蚀模型进行数值分析的新方法——小波精细积分法。与传统的有限元方法相比,本文方法属于半解析方法,对时间步长不敏感,可有效提高计算效率。数值分析结果表明了该方法的有效性。
A new numerical method on rill erosion model was proposed by combining the wavelet collocation method with the precise integration method, which is called wavelet precise integration method （WPIM）. Comparing with the classic finite element method, WPIM belongs to a half analytical method, it is not sensitive to the time step, so this is helpful to improve the computational efficient. The numerical result showed that the method is effective.
