Fig. 11. Histograms of (ac) untransformed and (df) loge-transformed dispersivities in different transport distance classes: (a) and (d) from 0 to 30 cm, (b) and (e) from 31 to 80 cm, and (c) and (f) from 81 to 200 cm; µ and
are the mean and standard deviation of the loge-transformed dispersivities, respectively. (Data from experiments with ponding boundary conditions and from experiments with a flow rate >10 cm d1 were excluded; data from the same experiment in a travel distance class were averaged and treated as a single entry.)
