a A scaled version of Fig. 10b with the exponential [Eq. (8)] fits (broken lines). \(T_{\mathrm{slide}}\) is defined at the threshold \(v_{\mathrm{0}} = 0.1\) mm/s. b Growth rate A obtained from the fits in a plotted versus hydraulic head \(h_{\mathrm{w}}\). c Inverse velocity (\(\Lambda = 1 / v_{\mathrm{z}}\)) versus \(t - T_{\mathrm{slide}}\) version of Fig. 10b. d Acceleration \(a_{\mathrm{z}}\) versus velocity \(v_{\mathrm{z}}\) (see text for details). The marker colors correspond to the \(h_{\mathrm{w}}\) shown in c. A line indicates a power-law fit [Eq. (9)] to the \(h_{\mathrm{w}} = 10\) cm case (\(\bigtriangleup\)) from which we obtain a power-law exponent \(\alpha = 1.1 \pm 0.1\). e \(\alpha\) versus \(h_{\mathrm{w}}\) obtained from the power-law fits
