Abstract

 Characteristics of two-dimensional turbid density currents and the effects of their confining were experimentally investigated. Sedimentation rates of confined turbidity currents in 10% channel width were measured. Data show that at low bed slopes (less than 2%), two - dimensional density currents are laminar and subcritical and entrainment is low. Meanwhile coarser particles deposit at the bed continuously, silt and clay particles can suspend. Increasing in concentration and bed slope, decrease the height of density current and increase the average velocity. Confining of turbidity current increases the height and velocity in several times and can change the subcritical regime to supercritical flow. This can alter the flow from depositive to erosive. In this case, even at low bed slope, the flow might become supercritical and its turbulence and perturbation remains coarser particles in suspension. Sedimentation profiles of confined turbidity currents show that sedimentation mass was reduced considerably.
