Abstract
A vortex model is employed to calculate the flow induced by a line group of submerged high velocity shallow water jets discharging in proximity to a shoreline boundary. Based on an inviscid flow model, a kinematic and dynamic boundary condition are formulated along the unknown lines of velocity discontinuity downstream of the multiple jets. This results in two governing nonlinear integral equations in terms of the unknown circulation strength along the unknown slip streamlines. The numerically computed two dimensional momentum-induced flow shows that, as the jet group is placed closer to the boundary, the contraction of the slipstream becomes stronger, resulting in a decrease of the induced flow. All of the features predicted by the theory are in good agreement with experimental results of this and previous investigations.
