IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ervation and flume experiments indicate that bedload in meanders transports along the same-side bank and/or
towards the opposite bank. However, quantitative study can barely be found in previous literature. The authors simulate
the transport of flow and bedload in a 110° sine-generated laboratorial meandering flume by applying a two-dimensional
depth-averaged, unsteady, flow and sediment transport model, i.e. CCHE2D. Calculated results indicate two scouring
zones during the process of bed deformation, i.e. foreside of point bars at convex bank and erosion zone near concave
banks. Sediment eroded from these two zones mainly transport along the same-side channel bank rather than crossing
the channel centerline and moving towards the opposite bank in the early stage of bed deformation. However, after the
topography being built, the main flow will gradually converge towards concave banks. Meanwhile, moving particles are
constrained within the belt of “concave bank – crossing bars - concave bank”.Form Required
