Description :
This paper describes a method developed to use root-architecture data, obtained in previous studies, to create regressions showing changes in the number of roots crossing a shear plane within in a stream bank over time. In addition, variations in root density with depth are studied so that root-reinforcement estimates obtained by RipRoot can be correctly applied to the layering within model runs of the bank stability and toe erosion model (BSTEM). It was found that stream-bank varied the most when the proportion of the failure plane length to the depth of the rooting zone was greatest.
