A flow caused by a line sink/source is considered in a channel of finite depth. The sink is placed at the bottom of the channel, and produces a free surface with a cusp pointing to the sink. Numerical solutions of this free-surface flow are computed by an integral equation method. The relationship between the nondimensional parameter Froude number F, based on the downstream flow, and the distance of the separation point of the cusp to the sink is presented as a plot from our computations. When we obtain the limiting cusp solution with . Full text: PDF
