| Abstract: | An excavation scheme on Lijia sediment bar of Jialing river was put forward based on site investigation, and a two-dimensional horizontal numerical model in orthogonal body-fitted coordinate for flow was established to study the variation of flow condition at Lijia reach caused by excavation. The results of calculation shows that the effect of excavation on riverbed evolution, navigation, flood carrying capacity and wading engineering of Jialing river is very small. |
| Keywords: | excavation two-dimensional horizontal numerical mode riverbed evolution |
