Fig. 8. The index of compaction of all models at the highest unidirectional flow
speed (73 cm s-1). Values are means ± s.d., N=6.
Only the most flexible models were significantly compacted, and backreef
models more so than forereef models, as determined by Kruskall-Wallis
non-parametric analysis (H=30.23, d.f.=11, P<0.05) and
Nemenyi post-hoc multiple comparisons
(Zar, 1999). Letters that are
different indicate significant differences between groups as determined by
Nemenyi post-hoc multiple comparisons
(Zar, 1999).
