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.

STUDY OF NUMERICAL MODEL TO CALCULATE THE RIVERBANK EROSION IN TIEN RIVER, THROUGH LONG HO DISTRICT OF VINH LONG PROVINCE

The paper presents the application of the numerical models used to calculate the riverbank failure in Tien River, which flows through Long Ho district of Vinh Long province. The two-dimensional (2D) model is based on the system of non-linear equations including Reynolds equations, sediment transport, and bed load continuity equation to simulate the flow, sediment transport and bed changes in the river. Then the model is combined with Geo-slope model in order to calculate the probability of riverbank failure. The obtained results show that the stability of riverbank at this segment is low and potential to failure. Besides, the result of bank width retreat is compared with some observed data and received a good agreement. In conclusion, these results indicate that the approach in this study is promising and potentially applied in predicting and avoiding bank erosion in Vietnam river networks.
