Abstract: We investigate granular flows over an inclined, normally vibrated rigid base using the discrete element method, systematically varying the inclination angle (\ensuremath{\theta}), vibration frequency (f), and amplitude (A). Our findings demonstrate that vibrated bases can amplify the mass flow rate (Q) by 25--100 times compared to fixed bases depending upon the choice of parameters and, further, it is possible to find conditions that maintain Q nearly constant. Finally, Q is characterized by a dimensionless parameter S, also known as the shaking strength, which represents the ratio of vibrational to gravitational energies.
