  abstract  = {Turbidity currents play a significant role within the global sediment cycle, and are important for environmental processes as well as the formation of hydrocarbon reservoirs. A special kind of turbidity currents are tubidity currents with reversing buoy- ancy. Hyperpycnal flows are one kind of turbidity currents with reversing buoyancy. There exist numerous experimental studies of these flows but no simulations. This thesis deals with reversing-buoyancy turbidity currents. The propagation of the flow front over time and the later lift-off are investigated on the basis of the results from Sparks et al. (1993). Furthermore the interaction of the current with obstacles is analyzed by means of the work from Stevenson \& Peakall (2010). Hereby a closer look at deposit patterns caused by various obstacle positions and dimensions, is taken. Towards this end a highly parallel three-dimensional Navier-Stokes Direct Numerical Simulation code is used.},
