An Assessment of the Literature and Recent Developments on the Shallow Wake in an Open Channel Flow

Figure 2

Widening of the wake close to the free-surface (Adopted from Logory et al., [41]). The contour color represents mean velocity; white to dark shade represents higher to lower range of streamwise velocity. 𝜃₀ (= 3.1 mm) is the half-momentum thickness of the wake (Reproduced with the permission of American Institute of Physics).
