The spatio-temporal scaling relationship for individual channels in braided streams is shown to be identical to the spatiotemporal scaling associated with constant Froude number, e.g. FrZ1. A means to derive this relationship is developed from a new theory of sediment transport. The mechanism by which the FrZ1 condition apparently governs the scaling seems to derive from the sensitivity of sedi...

The intrusion of a constant density fluid at the interface of a two-layer fluid is considered. Numerical solutions are computed for a model of a steady intrusion resulting from flow down a bank and across a broad lake or reservoir. The incoming fluid is homogeneous and spreads across the lake at its level of neutral buoyancy. Solutions are obtained for a range of different inflow angles, flow r...
