3.2 | Log vane analysis
The likelihood ratio test for the integrity CLM (Table 5) indicated that
slope affected rankings for log vanes (p = 0.056), while
preexisting morphology did not (p = 0.571). The difference
between threshold coefficients occurred between intact and all higher
(damaged through failed) rankings (p = 0.001). Flatter slopes
increased the likelihood of higher integrity rankings for log vanes
(Figure 3; Table 5). Although the angle of departure was not included as
an explanatory variable in the model due to correlation with log-vane
slope, the negative slope for that relationship indicated that flatter
slopes were associated with greater angle of departures. Neither slope
(p = 0.196) nor morphology (p = 0.774) affected rankings
for erosion, and no differences between threshold coefficients were
observed (p > 0.5). Results from the CLM for
log-vane deposition indicated that morphology had a significant effect
on rankings (p = 0.013) while slope did not (p = 0.142).
Log-vanes that were placed in riffles were more likely to receive higher
deposition rankings when compared to pools (Figure 3), and those
difference occurred between moderate and severe rankings (p =
0.001).
