Practical Application of 1-D Sediment Transport Model

摘要

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 the River Raba - a mountain tributary of the Vistula 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 Krakow-Zakopane 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.
