The formation of a hydrothermal plume has been recently found in the main basin of a karstic lake. The hydrothermal plume carries a concentration of particles in suspension that are transported up to an equilibrium depth. At the equilibrium level, particles are transported horizontally as a turbidity current. The particle volume concentration in the hypolimnion, where the turbidity current occurs, has been found to be homogeneous for points close to the source of the plume. However, there is a decrease in the particle concentration points from close to the source of the plume to the points far from the source, which indicates that the sedimentation of particles from the turbidity current occurs. This sedimentation process has been attributed mainly to double diffusive sedimentation rather than to single particle sedimentation. Here we demonstrate the effect of this turbidity current on the zonal sedimentation rates at the southern lobe of the lake.
