Figure 9. The proportion of the colluvium thickness (h/z) that is saturated for a given log(q/T) at the Mettman Ridge. Not that the larger the negative number, the smaller the ratio q/T and the smaller the precipitation needed to cause instability. Unit of q/T is 1/meters. Value of log(q/T) is given in the upper right corner of each of the 6 maps. Contour interval is 5 m and grid size is 2 m.
