Abstract:

This study presents the hydrodynamic modelling of ocean currents along the Canyon São Tomé, Campos Basin, Brazil, and their impact on sediment transport. The objective is to develop a tool to simulate the interaction between bottom currents and the submarine physiography, and to depict the relative importance of any individual current forcing mechanism as a sediment-reworking agent. This paper presents the evolution of along-channel currents over a tidal cycle and the simulation of a turbidity current. The resultant sediment transport under the combination of turbidity and oceanic currents is also simulated. This model is a step forward towards the understanding of the geometric and textural modifications imposed by bottom currents upon gravity-driven deposits, which is of great importance for the oil industry.
