Study of flow separation which can be observed at the leading edge of a spilling breaker of 'white-cap', at the lower edge of a tidal bore or hydraulic jump and upstream of an obstacle abutting a steady free-surface flow. At the point of flow separation there is a discontinuity in the slope of the free surface. The flow upstream of this point is relatively smooth; the flow downstream of the discontinuity is turbulent. A local solution for the flow in the neighborhood of the discontinuity is derived. The turbulence is represented by a constant eddy viscosity, and the tangential stress across the interface between the laminar and turbulent zones is expressed in terms of a drag coefficient.
