Topography evolution in convergent flows of two liquid layers
We have recently developed a two-layer model that considers the convergent motion of two initially uniform liquid layer with different densities and viscosities and assumes that the flow is due to the basal traction that acts at the bottom of the lower layer. We have used this model to describe succ...
