Numerical nonlinear analysis of alternate-bar formation and overdeepening under superresonant conditions (abstract)

Numerical nonlinear analysis of alternate-bar formation and overdeepening under superresonant conditions (poster)

Local geometrical perturbations in alluvial channels can generate a pattern of alternate bars called ‘overdeepening’. Previous linear analyses and laboratory experiments showed that these bars arise downstream of perturbations in the relatively narrow and deep channels corresponding to subresonant conditions, but both upstream and downstream of...
