What controls the structure of turbidity currents?

This study analyzes turbidity currents across multiple systems using high-resolution oceanographic datasets and laboratory experiments. By comparing velocity trends throughout the turbidity currents, we identify two end-member types: short surge flows where peak velocity is followed by rapid decay in velocity and sustained flows where peak velocity is followed by a prolonged near constant velocity. Variability is explored across key parameters, including trigger, system type, slope, grain size, and distance offshore. The findings demonstrate that no single parameter explains all observed variations, with only grain size and distance offshore showing some degree of correlation with the type. Improved data quality, particularly on grain size variability within systems and individual flows, will be essential to understand the different types of flows and their relative process.
