ONE-DIMENSIONAL NUMERICAL MODEL FOR NONUNIFORM SEDIMENT TRANSPORT UNDER UNSTEADY FLOWS IN CHANNEL NETWORKS

One-dimensional model for simulating the non-equilibrium transport of non-uniform total load under unsteady flow conditions in dendritic channel networks with hydraulic structures. Equations of sediment transport, bed changes and bed-material sorting were solved. Utilisation of a coupled procedure that shows best results than decoupled models. Predictions were obtained with a reasonable accuracy and reliability.
