Turbidity currents are significant due to their role in dictating reservoir sedimentation, the safety of deep sea facilities and the formation of submarine morphological features and turbidites. Interactions exist between turbidity current, sediment transport, bed topography and deformation. However, existing mathematical models have ignored these interactions either partly or completely. Therefore these models can be referred to as decoupled or partially coupled models. Uncertainties arising from these simplifications remain unclear. To help address this, the present study advances modelling capability and understanding of turbidity currents in three areas. First, the significance of the interactions is analysed theoretically. Second, a fully coupled mathematical model, which incorporates explicitly the interactions between turbidity current, sediment tra
