“…Video cameras recorded flow-bed interactions and depositional processes. Ultrahigh concentration meters (Felix et al, 2005;Manica, 2012) measured suspended sediment concentrations at different levels below and above the bed surface at a horizontal distance x ≈ 3.5 m from the inlet. An ultrasound scanner recorded the interface between substrate and turbidity current at x ≈ 1.7 m (Figs.…”

“…Process models for turbidity current deposits (i.e., turbidites) are based on field observations and laboratory and computer simulations (e.g., Postma et al, 1988;Baas et al, 2004;Cantero et al, 2012;Manica, 2012). These simulations typically model fixed or loose sandy substrates.…”

“…High-density flows (more viscous) have more sediment transport capacity than low-density flows (less viscous) when they keep their rheological (Newtonian) and turbulent behaviour along the system (Baas et al 2004, Manica 2009, Manica 2012, Talling et al 2012. This is a key point in support of the higher L/W ratio of the HDTC fans in relation to LDTC fans.…”

“…O termo "turbidez" se refere à quantidade de sição das partículas, o que altera o comportamento reológico do fluxo (Manica 2011). Este tipo de fluxo pode ser newtoniano, não-newtoniano ou granular (binghamiano).…”

“…Fisicamente, os fluxos coesos são não-newtonianos, enquanto as correntes de turbidez são fluxos newtonianos, ao menos em sua parte superior. Manica (2011) demonstrou, com uso de experimentos, que as correntes de turbidez podem ter uma camada basal que se comporta como um fluxo coeso, a depender da concentração de argila.…”
