Abstract
Gravity currents can occur in the ocean due to underwater landslides and play a critical role in sediment transport. The focus of this study is to characterize the influence of bed slope on the propagation of axisymmetric gravity currents. The research focuses on analyzing the front velocity, turbulent structures, and the potential formation of hydraulic jumps. The findings highlight the influence of bed slope on the spreading dynamics, the size and intensity of turbulent structures, and the conditions leading to hydraulic jumps. The results are based on numerical simulations, which are made possible by the resources provided by PUCRS High Performance Laboratory. This research is funded by Petrobras.
