Direct numerical simulations of open‐channel flow indicate that turbulence at the free surface contains large‐scale persistent structures. They are ‘‘upwellings’’ caused by impingement of bursts emanating from the bottom boundary; ‘‘downdrafts’’ in regions where adjacent upwellings interact, and whirlpool‐like ...
