In Figure <br />12 the black clipboard is shown for scale, and the e~ctent of the toe erosion is more th two feet <br />~ <br />into the bank. This erosion causes the entire bank to be supported as a cantilever beanp, and the <br />entire bank will eventually fail. Figure 13 is of another location showing where the <br />already occurred.
