From: Sedimentation and drag in drifting macrophytes and plastic objects: a model

Correlations between sedimentation and morphological traits of macrophytes. Sedimentation velocity ω of 49 macrophyte specimens was correlated with (A) their nominal diameter, (B) their relative density and (C) their shape factor. Best fitting semilogarithmic functions and their 95% confidence intervals are shown (in all three cases p < 0.0001).
