Equilibrium sediment transport can be considerably affected by an excess (or deficiency) of sediment supply due to mostly flows during flash floods or floods resulting from dam break or dike failure. In such situations the sediment transport process occurs under nonequilibrium conditions, and extensive changes in alluvial river morphology can take place over a relatively short period of time. Therefore the study and prediction of these changes are important for sustainable development and use of river water. This study hence developed a mathematical model based on the kinematic wave theory to model transient bed profiles in alluvial channels under nonequilibrium conditions. The kinematic wave theory employs a functional relation between sediment transport rate and concentration, the shear-stress approach for flow transport capacity, and a relation between flow velocity and depth. The model satisfactorily simulated transient bed forms observed in laboratory experiments. en_US dc.language.iso eng en_US dc.publisher American Geophysical Union en_US dc.relation.isversionof 10.1029/2006WR005681 en_US dc.rights info:eu-repo/semantics/openAccess en_US dc.subject Water waves en_US dc.subject Alluvial channels en_US dc.subject Kinematic wave model en_US dc.subject Diffusion en_US dc.subject Nonequilibrium conditions en_US dc.subject Transient bed profiles en_US dc.title Kinematic wave model for transient bed profiles in alluvial channels under nonequilibrium conditions en_US dc.type article en_US dc.contributor.authorID TR2054 en_US dc.contributor.institutionauthor Tayfur, Gökmen dc.relation.journal Water Resources Research en_US dc.contributor.department Izmir Institute of Technology.
