Practical application of 1-D Sediment Transport Model
Application de modèles 1D de transport de sédiments
Résumé
The aim of the paper is to present a numerical simulation of sediment transport in a mountain river. Two one-dimensional sediment transport models: RubarBE and Metoda are applied to predict variation of longitudinal bed profile along the river reach and changes in the cross-sectional geometry due to erosion or deposition of sediment. In the current paper, simulation of the sediment transport is applied for the experimental reach of Raba River a mountain tributary of the Wisla River. The reach is located from 81.829 km to 77.751 km upstream from the Dobczyce Dam. This part of the river was completely changed due to the project concerning the extension of the ,,Zakopianka' road, which is located next to the Raba River. The results of simulation of riverbed evolution, before and after river training carried out by both models, are analysed and discussed.
Le but de cet article est de présenter une simulation numérique de transport de sédiment dans une rivière de montagne. Deux modèles RubarBE et Metoda sont appliqués pour prédire la variation du profil en long et les changements de section en travers due aux dépots et érosions. La simulation porte sur la Raba, affluent de la Vistule. Ce bief a té modifié suite à la construction de la route Cracovie-Zakopane. Les résultats avant at après aménagement sont analysés et discutés.
