Their analysis shows that the circulation in the gravitycurrent does not influence the propagation. Downstream of the gravitycurrent head the flow is in three layers. Each integral curve corresponds to a certain self-similar gravitycurrent satisfying a particular set of initial and boundary conditions. In our solution there is intensive circulation with strong vorticity inside the gravitycurrent and the dynamics is nonhydrostatic. However, one natural limit concerns the evolution of a continuously stratified gravitycurrent. In our solution the head of the gravitycurrent is a strong vortex and the dynamics are non-hydrostatic. In our solution there is intensive circulation with strong vorticity inside the gravitycurrent and the dynamics is non-hydrostatic. The gravitycurrent disturbance then generates only a stationary wave pattern. To examine the hydrodynamic instability behind the lobe-and-cleft structure, we have undertaken a stability analysis of the flow at the head of a gravitycurrent. The supercritical regime is defined as when the propagation speed of the disturbance is less than the speed of the gravitycurrent. The gravitycurrent is in the slumping phase in each view. Schematic illustrating the structure of a density-stratified gravitycurrent in a porous layer. Clearly, knowledge of the topology at the head of a gravitycurrent is a prerequisite for any theoretical treatment of the flow. The nonlinear advection term in most of the cases investigated here tends to slow the propagation of the gravitycurrent. In the present case the mean-flow component is the two-dimensional, steady-state flow at the foremost part of the gravitycurrent, while the disturbance is assumed to be three-dimensional.
