河岸强度对河道几何形状有重要影响，但这种关系的量化仅限于少数特定情况。这是由于河岸强度的复杂性以及将其影响纳入河道几何关系的困难。为了进行广泛的现场观测的综合分析，本研究采用了最近开发的通道几何形状的多变量模型。当银行的横向稳定的河流数量进行分类的基础上的银行沉积物和植被，多变量模型产生的银行强度的数值指标。在所分析的数据范围内，河岸强度可使河道宽度产生三倍的变化，使深度产生两倍的变化，这相当于横截面积产生约1.6倍的变化。© 1998 John Wiley & Sons，Ltd.
Bank strength exerts a significant influence on river channel geometry, but quantification of this relationship has been limited to only a few specific circumstances. This is due to both the complex nature of bank strength and the difficulty in incorporating its influence in river channel geometry relations. In order to undertake an integrated analysis of wide-ranging field observations, this study applies a recently developed multivariate model of channel geometry. When the banks of a number of laterally stable streams are categorized on the basis of the bank sediment and vegetation, the multivariate model yields numerical indices of bank strength. Within the range of the data analysed, bank strength can produce a three-fold change in channel width and a two-fold change in depth corresponding to about a 1·6-fold change in cross-sectional area. © 1998 John Wiley & Sons, Ltd.
