Consider a two-dimensional, irrotational flow of ideal, incompressible and immiscible fluids in two layers, under the action of gravity, bounded below by a horizontal rigid bottom and above by an unbounded layer of fluid, as shown in figure 1.The dynamics in the upper layer of fluid is neglected and all its … WebSep 8, 2010 · A two-layer approach for depth-limited open-channel flow with submerged vegetation is described. A momentum balance is applied to each layer and expressions for the mean velocities are proposed. The velocity is assumed to be uniform in the vegetation layer and logarithmic in the upper layer.
