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.

Towards a nonlinear meander evolution model
Author : Shiyan Zhang1, Dong Chen1*, Koen Blanckaert2 , Willem Ottevanger3, Leilei Gu1
ABSTRACT: The evolution of meanders has been the focus of research challenging
river engineers for decades. The study simulates the natural evolution of meandering
processes by coupling a nonlinear flow model (by Blanckaert and de Vriend, 2010)
with the Bank Erosion and Retreat Model (BERM, by Chen and Duan, 2006).
Distinguished from our linear meander evolution model (Chen and Duan, 2006)
which adopted the first-order analytical solution of flow field in a sine-generated
channel (by Johannesson and Parker, 1989b), the present model is applicable to any
channel planforms without curvature restrictions therefore more suitable for
moderately and highly curved channels. The computed results demonstrate the
improvement of simulation of meander evolution by adopting the advanced
hydrodynamic model.
