Fig. 7. Textural variables compared with maximum water content (_max) and Rossi–Nimmo (1994) fit parameters (scaling parameter for water potential, _o; curve-shape parameter, ). Scatter plots show comparisons with (a, c, e) geometric mean particle diameter (M_g) and (b, d, f) geometric standard deviation (_g), for n = 10 samples. Symbols indicate sample categories of Fig. 3, with results for individual samples listed in Table 3. Solid symbols represent fluvial samples and open symbols represent debris flow samples.
