Fig. 4: Mixing interface with intermodal behaviour: scale relations and comparison of predictions and measurements.
From: Mixing dynamics at river confluences governed by intermodal behaviour
a, In mixing-layer mode with a small wake effect (solid blue line is equation (8); dashed line is hyperbolic tangent function37). b, In wake mode with a small mixing-layer effect. c, Mixing with a weak wake effect (40°, Mr = 5; solid red line is equation (6), red dashed line is free mixing layer, solid blue line is equation (7) and dashed blue line is free wake). d, Mixing with a weak mixing-layer effect (40°, Mr = 2, the same definitions for lines as in c).
