The DEM results took more than two months of computational time, whereas the continuum model is completed in a fraction of a second, albeit without detail of individual particle kinematics and adjustment towards the critical state. -\begin{figure}[htbp] - \begin{center} - \includegraphics[width=0.49\textwidth]{experiments/fig-stick_slip_stress.pdf} - \includegraphics[width=0.49\textwidth]{experiments/fig-stick_slip_rate.pdf} - \caption{\label{fig:stick_slip}% - Stick-slip dynamics during sinusoidal water-pressure forcing from the top. - Stress and shear velocity are measured at the top of the sediment bed. - a-d) Stress-controlled setup with applied friction $\mu$ = 0.4. - e-h) Rate-controlled setup with applied shear velocity $v_x$ = 1 km/a. - } - \end{center} -\end{figure} - -Next we vary the top water pressure and observe the shear dynamics over a simulation time of seven days (Fig.~\ref{fig:stick_slip}). +Next we vary the top water pressure in a sinusoidal manner and observe the shear dynamics over a simulation time of seven days (Fig.~S1). The experiments are performed under both stress and rate-controlled configurations. The response during the first cycle ($t<1$ d) is slightly different from later cycles ($t>1$ d) as the model is initialized with a hydrostatic water-pressure distribution. Under stress-controlled conditions (Fig.~\ref{fig:stick_slip}a-d), the system shows stick-slip behavior where velocities range from 0 to $\sim$9 km/d (Fig.~\ref{fig:stick_slip}b).
