这种扰动分析的发散/收敛对山坡入渗和下坡非饱和流的影响表明，在一般情况下，这些影响是不重要的，通常的山坡地形。只有当轮廓半径小于特征渗透长度lgrav的约10倍（或吸附长度的10倍）时，才需要考虑扰动。这一结果开辟了一个相当大的扩展的适用性分析的渗透平面山坡拥抱斜坡曲线轮廓，如山脊的鼻子和凹陷。
This perturbation analysis of divergence/convergence effects on hillslope infiltration and downslope unsaturated flow indicates that, in general, these effects are unimportant for usual hillslope topography. Only where the radius of the contour is less than about 10 times the characteristic infiltration length lgrav (or 10 times the sorptive length) need the perturbation be taken into account. This result opens up a considerable extension of applicability of the analysis of infiltration on planar hillslopes to embrace slopes with curved contours, such as ridge noses and hollows.
