| Abstract: | 1D stream model is made for the Pearl River delta networks and 2D stream-sediment model for engineering neighboring river.Engineering river current stream characteristic during flood and dry season has been analyzed , the conditions of limit scour , such as hydrology , sediment, sediment parameters and the other conditions , have been rationally designed .Besides, limit erosion that might happen in Chencun river has been forecasted .Based on the result , morphological changes of riverbed cross section , beach and slot situation after limit scour have been studied , and the rationality of burying deep for the tunnel has been estimated . |
